Harness Connector Inspection
CONNECTOR CONTINUITY AND VOLTAGE TEST
Required Special Tools:
- MB991219: Test Harness Set
- MD998459: Test Harness
Follow the steps below to avoid causing poor connector contact and/or reduced waterproof
performance of connectors when checking continuity and/or voltage at terminals of waterproof
connectors.
CAUTION: Never backprobe a waterproof connector. Backprobing this type of a connector may
cause the terminals to corrode, deteriorating circuit performance.
1. If the circuit is to be checked in the closed state, use a special tool such as MD998459.
CAUTION: Forcing the probe into the terminal may open the terminal, causing intermittent or poor
contact and creating an open circuit.
2. If the connector is disconnected for checking and the facing part is the female pin side, use an
appropriate male terminal for checking the contact
pressure of connector pins (such as MB991219).
CAUTION: Do not contact more than one terminal with the probe at the same time. Contacting two
or more terminals at the same time may damage a circuit, possibly to the point of starting an
electrical fire.
3. If the facing part is the male pin side, either carefully touch the probe to the pin so it does not
accidently contact other pins, or use an appropriate
female terminal.

Cable and Wires Check
1. Check connections for looseness, rust, and stains. 2. Check terminals and wires for corrosion by
battery electrolyte, etc. 3. Check terminals and wires for open circuit or frayed wires. 4. Check wire
insulation and coating for damage, cracks, and wear. 5. Check conductive parts of terminals for
contact with other metallic parts (vehicle body and other parts). 6. Check grounding parts to verify
that there is complete continuity between attaching bolt(s) and vehicle body. 7. Check for incorrect
wiring. 8. Check that harnesses are secured to prevent contact with sharp edges and corners or
hot parts (exhaust manifold, pipe, etc.). 9. Check that harnesses are secured firmly to provide
enough clearance from the fan pulley, fan belt, and other rotating or moving parts.
10. Check that the harness between fixed parts (such as the vehicle body) and vibrating parts
(such as the engine) are long enough to allow for
vibration and movement.
Battery Handling
WARNING: Battery posts, terminals and related accessories contain lead and lead compounds.
WASH HANDS AFTER HANDLING
When checking or servicing does not require power from the vehicle battery, be sure to disconnect
the cable from the battery (-) terminal. This will prevent problems that could be caused by a short
circuit. Disconnect the (-) battery terminal first and reconnect it last.
Cautions In Event of Blown Fuse
When a fuse is blown, there are two probable causes. One is that it is blown due to flow of current
exceeding its rating. The other is that it is blown due to repeated on/off current flowing through it.
Which of the two causes is responsible can be easily determined by visual check as described
below.
Page 28
Dodge Stratus Coupe Workshop Manual (L4-2.4L VIN G (2003))
Dodge Workshop Manuals > Relays and Modules > Relays and Modules - HVAC > Blower Motor Relay > Component
Information > Diagrams > Diagram Information and Instructions > Page 44
Page 29
1. Fuse blown due to current exceeding rating
The illustration shows the state of a fuse blown due to this cause. In this case, do not replace the
fuse with a new one hastily since a current heavy enough to blow the fuse has flowed through it.
First, check the circuit for shorts and check for abnormal electric parts. After correcting shorts or
replacing parts, use only a fuse of the same capacity as a replacement. Never use a fuse of larger
capacity than the original fuse. If a larger capacity fuse is used, electric parts or wiring could be
damaged, or could start a fire.
2. Fuse blown due to repeated turning current on and off The illustration shows the state of a fuse
blown due to repeated current on/off. Normally,
this type of problem occurs after a fairly long period of use and is less frequent than above. In this
case, simply replace with a new fuse of the same capacity.
Checking Fuses
A blade type fuse has test taps provided to allow checking of the fuse itself without removing it from
the fuse block. The fuse is okay if the test light comes on when its one lead is connected to the test
taps (one at a time) and the other lead is grounded. Remember to turn the ignition switch to ON to
ensure all circuits are live.
Checking Relays
NOTE: The deenergized state means that no current is flowing through the coil. The energized
state means that current is flowing through the coil.
Page 30
Dodge Stratus Coupe Workshop Manual (L4-2.4L VIN G (2003))
Dodge Workshop Manuals > Relays and Modules > Relays and Modules - HVAC > Blower Motor Relay > Component
Information > Diagrams > Diagram Information and Instructions > Page 45
Page 31
1. When current flows through the coil of a relay, its core is magnetized to attract the iron piece,
closing (ON) the contact at the tip of the iron piece.
When the coil current is turned off, the iron piece returns to its original position by a spring, opening
the contact (OFF).
2. By using a relay, a heavy current can be turned on and off by a switch using much less current.
For example, in the circuit shown here, when the
switch is turned on (closed), current flows to the coil of the relay. Then, its contact is turned on
(closed) and the light comes on. The current flowing through the switch is much less than that for
the light.
3. Relays may be classified as the normally open-type or the normally closed-type, depending on
their contact construction.
When a normally closed relay as illustrated here is checked, there should be continuity between
terminals 1 and 2 and between terminals 3 and 4 when the relay is deenergized. There should be
no continuity between terminals 3 and 4 when battery voltage is applied between terminals 1 and 2.
Checking Switches
In a circuit diagram, a switch is shown in the normal condition.
Page 32

1. Normally open or normally closed switch
Switches are classified into those which open the circuit and those which close the circuit when off.
Switches are shown in their normal state unless specified otherwise.
Page 33
2. Switch connection
This figure illustrates a complex switch. The continuity between terminals at each position is as
indicated in the table below.
General Electrical System Check
GENERAL ELECTRICAL SYSTEM CHECK
A circuit consists of the power supply, switch, relay, load, ground, etc. "there are various methods
to check a circuit including an overall check, voltage check, short-circuit check, and continuity
check. Each of the methods briefly described below apply only to circuits similar to the illustration.

Information > Diagrams > Diagram Information and Instructions > Page 47
Page 35
1. VOLTAGE CHECK
1. Ground one lead wire of the test light. If a voltmeter is used instead of the test light, ground the
grounding side lead wire. 2. Connect the other lead wire of the test light to the power side terminal
of the switch connector. The test light should come on or the voltmeter
should indicate a voltage.
3. Then, connect the test tight or voltmeter to the motor connector. The test light should not come
on, or the voltmeter should indicate no voltage.
When the switch is turned ON in this state, the test light should come on, or the voltmeter should
indicate a voltage, with the motor starting to run.
4. The circuit illustrated here is normal. If there is any problem, such as the motor failing to run,
check voltages beginning at the connector
nearest to the motor until the faulty part is identified.
2. SHORT-CIRCUIT CHECK
Because the fuse has blown, it is probable that there is a short circuit. Follow the procedures below
to identify the short-circuit location.
STEP 1. Remove the blown fuse and connect the test light across the fuse terminals (Circuit
switch: OFF).
Q: Does the test light illuminate?
YES: Short-circuit exists between the fuse block and the switch. Repair the harness between the
fuse block and the switch.

Information > Diagrams > Diagram Information and Instructions > Page 48
Page 37
NO: Go to Step 2.
STEP 2. Turn the switch ON and disconnect the illumination light connector.
Q: Does the test light illuminate?
YES: Short-circuit exists between the switch and the connector. Repair the harness between the
switch and the connector. NO: Short-circuit exists between the connector and the illumination light.
Repair the harness between the switch and the connector.

Page 39
3. CONTINUITY CHECK
1. When the switch is in the "OFF" position and the contact points of terminals 1 and 2 are
connected, the self-powered test light should
illuminate or the ohmmeter should read 0 ohm.
2. When the switch is the "ON" position and the contact points of terminals 3 and 4 are connected,
the self-powered test light should come on or
the ohmmeter should read 0 ohm.
Information For Diagnosis
INFORMATION FOR DIAGNOSIS
This manual contains the harness diagrams as well as the individual circuit drawings, operational
explanations, and troubleshooting hints for each component. The information is presented in the
following manner:
1. Connector diagrams show the connector positions, etc., on the actual vehicle as well as the
harness path. 2. Circuit diagrams show the configuration of the circuit with all switches in their
normal positions. 3. Operational explanations include circuit drawings of voltage flow when the
switch is operated and how the component reacts. 4. Troubleshooting hints include numerous
examples of problems which might occur. Most of the problems can be traced backward in a
common-sense manner to the origin of the trouble. Problems whose origins may not be found in
this manner are pursued through the various system circuits.
NOTE: Components of MFI, ETACS, etc. with ECU do not include 3 and 4 above. For this
information, refer to a relevant sections that includes details of these components.
Inspection
1. Sight and sound checks
Check relay operation, blower motor rotation, light illumination, etc. Listen for a "click" when relay
covers are pushed down.
2. Simple checks
For example, if a headlight does not come on, a faulty fuse or poor grounding is suspected.
Replace the fuse with a new one. Or use a jumper wire to ground the light to the body. Determine
which part(s) is/are responsible for the problem.

Page 41
3. Checking with instruments
Use an appropriate instrument in an adequate range and read the indication correctly.
Inspection Instruments
For inspection, use the following instruments:
1. Test lights
A test light consists of a 12V bulb and lead wires. It is used to check voltages or short circuits.
CAUTION: Never use a test light for checking ECU-related circuits or ECUs.
2. Self-powered test light
A self-powered test light consists of a bulb, battery and lead wires connected in series. It is used to
check continuity or grounding.
3. Jumper wire
A jumper wire is used to close an open circuit.

Dodge Stratus Coupe Workshop Manual (L4-2.4L VIN G (2003))
Dodge Workshop Manuals > Relays and Modules > Relays and Modules - HVAC > Blower Motor Relay > Component
Information > Diagrams > Diagram Information and Instructions > Page 51
CAUTION: Never use a jumper wire to connect a power supply directly to a load.
4. Voltmeter
A voltmeter is used to measure the circuit voltage. Normally, the positive (red lead) probe is applied
to the point of voltage measurement and the negative (black lead) probe to the body ground. Use a
digital voltmeter to check for voltage drop upstream and downstream of a component.
5. Ohmmeter
An ohmmeter is used to check continuity or measure resistance of a switch or a coil. If the
measuring range has been changed, the zero point must be adjusted before measurement.
Page 43
Troubleshooting Steps
HOW TO DIAGNOSE
The most important point in troubleshooting is to determine "Probable Cause." Once the probable
causes are determined, parts to be checked can be limited to those associated with such probable
causes. The determination of the probable causes must be based on a theory and be supported by
facts and must not be based on intuition only.

Cable and Wires Check
1. Check connections for looseness, rust, and stains. 2. Check terminals and wires for corrosion by
battery electrolyte, etc. 3. Check terminals and wires for open circuit or frayed wires. 4. Check wire
insulation and coating for damage, cracks, and wear. 5. Check conductive parts of terminals for
contact with other metallic parts (vehicle body and other parts). 6. Check grounding parts to verify
that there is complete continuity between attaching bolt(s) and vehicle body. 7. Check for incorrect
wiring. 8. Check that harnesses are secured to prevent contact with sharp edges and corners or
hot parts (exhaust manifold, pipe, etc.). 9. Check that harnesses are secured firmly to provide
enough clearance from the fan pulley, fan belt, and other rotating or moving parts.
10. Check that the harness between fixed parts (such as the vehicle body) and vibrating parts
(such as the engine) are long enough to allow for
vibration and movement.
Battery Handling
WARNING: Battery posts, terminals and related accessories contain lead and lead compounds.
WASH HANDS AFTER HANDLING
When checking or servicing does not require power from the vehicle battery, be sure to disconnect
the cable from the battery (-) terminal. This will prevent problems that could be caused by a short
circuit. Disconnect the (-) battery terminal first and reconnect it last.
Cautions In Event of Blown Fuse
When a fuse is blown, there are two probable causes. One is that it is blown due to flow of current
exceeding its rating. The other is that it is blown due to repeated on/off current flowing through it.
Which of the two causes is responsible can be easily determined by visual check as described
below.

Page 69
1. Fuse blown due to current exceeding rating
The illustration shows the state of a fuse blown due to this cause. In this case, do not replace the
fuse with a new one hastily since a current heavy enough to blow the fuse has flowed through it.
First, check the circuit for shorts and check for abnormal electric parts. After correcting shorts or
replacing parts, use only a fuse of the same capacity as a replacement. Never use a fuse of larger
capacity than the original fuse. If a larger capacity fuse is used, electric parts or wiring could be
damaged, or could start a fire.
2. Fuse blown due to repeated turning current on and off The illustration shows the state of a fuse
blown due to repeated current on/off. Normally,
this type of problem occurs after a fairly long period of use and is less frequent than above. In this
case, simply replace with a new fuse of the same capacity.
Checking Fuses
A blade type fuse has test taps provided to allow checking of the fuse itself without removing it from
the fuse block. The fuse is okay if the test light comes on when its one lead is connected to the test
taps (one at a time) and the other lead is grounded. Remember to turn the ignition switch to ON to
ensure all circuits are live.
Checking Relays
NOTE: The deenergized state means that no current is flowing through the coil. The energized
state means that current is flowing through the coil.

1. When current flows through the coil of a relay, its core is magnetized to attract the iron piece,
closing (ON) the contact at the tip of the iron piece.
When the coil current is turned off, the iron piece returns to its original position by a spring, opening
the contact (OFF).
2. By using a relay, a heavy current can be turned on and off by a switch using much less current.
For example, in the circuit shown here, when the
switch is turned on (closed), current flows to the coil of the relay. Then, its contact is turned on
(closed) and the light comes on. The current flowing through the switch is much less than that for
the light.
3. Relays may be classified as the normally open-type or the normally closed-type, depending on
their contact construction.
When a normally closed relay as illustrated here is checked, there should be continuity between
terminals 1 and 2 and between terminals 3 and 4 when the relay is deenergized. There should be
no continuity between terminals 3 and 4 when battery voltage is applied between terminals 1 and 2.
Checking Switches
In a circuit diagram, a switch is shown in the normal condition.

1. Normally open or normally closed switch
Switches are classified into those which open the circuit and those which close the circuit when off.
Switches are shown in their normal state unless specified otherwise.

2. Switch connection
This figure illustrates a complex switch. The continuity between terminals at each position is as
indicated in the table below.
General Electrical System Check
GENERAL ELECTRICAL SYSTEM CHECK
A circuit consists of the power supply, switch, relay, load, ground, etc. "there are various methods
to check a circuit including an overall check, voltage check, short-circuit check, and continuity
check. Each of the methods briefly described below apply only to circuits similar to the illustration.

Page 75
1. VOLTAGE CHECK
1. Ground one lead wire of the test light. If a voltmeter is used instead of the test light, ground the
grounding side lead wire. 2. Connect the other lead wire of the test light to the power side terminal
of the switch connector. The test light should come on or the voltmeter
should indicate a voltage.
3. Then, connect the test tight or voltmeter to the motor connector. The test light should not come
on, or the voltmeter should indicate no voltage.
When the switch is turned ON in this state, the test light should come on, or the voltmeter should
indicate a voltage, with the motor starting to run.
4. The circuit illustrated here is normal. If there is any problem, such as the motor failing to run,
check voltages beginning at the connector
nearest to the motor until the faulty part is identified.
2. SHORT-CIRCUIT CHECK
Because the fuse has blown, it is probable that there is a short circuit. Follow the procedures below
to identify the short-circuit location.
STEP 1. Remove the blown fuse and connect the test light across the fuse terminals (Circuit
switch: OFF).
Q: Does the test light illuminate?
YES: Short-circuit exists between the fuse block and the switch. Repair the harness between the
fuse block and the switch.

Information > Diagrams > Diagram Information and Instructions > Page 82
Page 77
NO: Go to Step 2.
STEP 2. Turn the switch ON and disconnect the illumination light connector.
Q: Does the test light illuminate?
YES: Short-circuit exists between the switch and the connector. Repair the harness between the
switch and the connector. NO: Short-circuit exists between the connector and the illumination light.
Repair the harness between the switch and the connector.

3. CONTINUITY CHECK
1. When the switch is in the "OFF" position and the contact points of terminals 1 and 2 are
connected, the self-powered test light should
illuminate or the ohmmeter should read 0 ohm.
2. When the switch is the "ON" position and the contact points of terminals 3 and 4 are connected,
the self-powered test light should come on or
the ohmmeter should read 0 ohm.
Information For Diagnosis
INFORMATION FOR DIAGNOSIS
This manual contains the harness diagrams as well as the individual circuit drawings, operational
explanations, and troubleshooting hints for each component. The information is presented in the
following manner:
1. Connector diagrams show the connector positions, etc., on the actual vehicle as well as the
harness path. 2. Circuit diagrams show the configuration of the circuit with all switches in their
normal positions. 3. Operational explanations include circuit drawings of voltage flow when the
switch is operated and how the component reacts. 4. Troubleshooting hints include numerous
examples of problems which might occur. Most of the problems can be traced backward in a
common-sense manner to the origin of the trouble. Problems whose origins may not be found in
this manner are pursued through the various system circuits.
NOTE: Components of MFI, ETACS, etc. with ECU do not include 3 and 4 above. For this
information, refer to a relevant sections that includes details of these components.
Inspection
1. Sight and sound checks
Check relay operation, blower motor rotation, light illumination, etc. Listen for a "click" when relay
covers are pushed down.
2. Simple checks
For example, if a headlight does not come on, a faulty fuse or poor grounding is suspected.
Replace the fuse with a new one. Or use a jumper wire to ground the light to the body. Determine
which part(s) is/are responsible for the problem.

3. Checking with instruments
Use an appropriate instrument in an adequate range and read the indication correctly.
Inspection Instruments
For inspection, use the following instruments:
1. Test lights
A test light consists of a 12V bulb and lead wires. It is used to check voltages or short circuits.
CAUTION: Never use a test light for checking ECU-related circuits or ECUs.
2. Self-powered test light
A self-powered test light consists of a bulb, battery and lead wires connected in series. It is used to
check continuity or grounding.
3. Jumper wire
A jumper wire is used to close an open circuit.

Dodge Workshop Manuals > Relays and Modules > Relays and Modules - HVAC > Control Module HVAC > Component
Information > Diagrams > Diagram Information and Instructions > Page 85
CAUTION: Never use a jumper wire to connect a power supply directly to a load.
4. Voltmeter
A voltmeter is used to measure the circuit voltage. Normally, the positive (red lead) probe is applied
to the point of voltage measurement and the negative (black lead) probe to the body ground. Use a
digital voltmeter to check for voltage drop upstream and downstream of a component.
5. Ohmmeter
An ohmmeter is used to check continuity or measure resistance of a switch or a coil. If the
measuring range has been changed, the zero point must be adjusted before measurement.

Troubleshooting Steps
HOW TO DIAGNOSE
The most important point in troubleshooting is to determine "Probable Cause." Once the probable
causes are determined, parts to be checked can be limited to those associated with such probable
causes. The determination of the probable causes must be based on a theory and be supported by
facts and must not be based on intuition only.
