Keyless Entry Module: Diagnostic Aids

Electrical Circuit Inspection Procedure

While there are various electrical circuit inspection methods, described here is a general method to check its open and short circuit by using an ohmmeterand a voltmeter.

OPEN CIRCUIT CHECK

Possible causes for the open circuit are as follows. As the cause is in the connector or terminal in many cases, they need to be checked particularlycarefully.

- Loose connection of connector

- Poor contact of terminal (due to dirt, corrosion or rust on it, poor contact tension, entry of foreign object etc.)

- Wire harness being open

When checking system circuits including an electronic control unit such as ECM, TCM, ABS control module, etc., it is important to perform carefulcheck, starting with items which are easier to check.

1. Disconnect negative (-) cable from battery2. Check each connector at both ends of the circuit being checked for loose connection. Also check lock condition of connector if equipped with
connector lock.

> Relays and Modules > Relays and Modules - Accessories and Optional Equipment > Keyless Entry Module > Component Information > Diagrams > Diagram Information

and Instructions > Page 23

Vitara JX (4Dr) 4WD L4-2.0L (2000)

3. Using a test male terminal, check both terminals of the circuit being checked for contact tension of its female terminal. Check each terminal
visually for poor contact (possibly caused by dirt, corrosion, rust entry of foreign object, etc.). At the same time, check to make sure that eachterminal is locked in the connector fully.

4. Using continuity check or voltage check the following procedure, check the wire harness for open circuit and poor connection with its terminals.
Locate abnormality, if any.

CONTINUITY CHECK

1. Measure resistance between connector terminals at both ends of the circuit being checked (between A-1 and C-1 in the figure). If no continuity is
indicated (infinity or over limit), that means that the circuit is open between terminals A-1 and C-1.

2. Disconnect the connector included in the circuit (connector-B in the figure) and measure resistance between terminals A-1 and B-1.

If no continuity is indicated, that means that the circuit is open between terminals A-1 and B-1. If continuity is indicated, there is an open circuitbetween terminals B-1 and C-1 or an abnormality in connector-B.

and Instructions > Page 24

Vitara JX (4Dr) 4WD L4-2.0L (2000)

VOLTAGE CHECK

If voltage is supplied to the circuit being checked, voltage check can be used as circuit check.

1. With all connectors connected and voltage applied to the circuit being checked, measure voltage between each terminal and body ground.
a. If measurements were taken as shown in the figure and results were as listed below, it means that the circuit is open between terminals B-1 and

A-1.

b. Also, if measured values were as listed below, it means that there is a resistance (abnormality) of such level that corresponds to the voltage

drop in the circuit between terminals A-1 and B-1.

5 V 5 V... 2 V

Voltage between:C-1 and body ground : Approx. B-1 and body ground : Approx. voltage dropA-1 and body ground : Approx. voltage drop3 V... 2 V

SHORT CIRCUIT CHECK (WIRE HARNESS TO GROUND)

Vitara JX (4Dr) 4WD L4-2.0L (2000)

5 V

Voltage between:C-1 and body ground : Approx. B-1 and body ground : Approx. A-1 and body ground : 5 V 0 V

1. Disconnect negative (-) cable at battery.2. Disconnect connectors at both ends of the circuit to be checked.

If the circuit to be checked is connected to other parts (1), disconnect all connectors of those parts. Otherwise, diagnosis will be misled.NOTE:

3. Measure resistance between terminal at one end of circuit (A-1 terminal in the figure) and body ground. If continuity is indicated, it means that
there is a short to ground between terminals A-1 and C-1 of the circuit.

4. Disconnect the connector included in circuit (connector B) and measure resistance between A-1 and body ground. If continuity is indicated, it
means that the circuit is shorted to the ground between terminals A-2 and B-1.

Intermittent and Poor Connection

Most intermittent are caused by faulty electrical connections or wiring, although a sticking relay or solenoid can occasionally be at fault. When checkingit for proper connection, perform careful check of suspect circuits for:

> Relays and Modules > Relays and Modules - Accessories and Optional Equipment > Keyless Entry Module > Component Information > Diagrams > Diagram Information

and Instructions > Page 26

Vitara JX (4Dr) 4WD L4-2.0L (2000)

- Poor mating of connector halves, or terminals not fully seated in the connector body (backed out).

­Dirt or corrosion on the terminals. The terminals must be clean and free of any foreign material which could impede proper terminal contact.However, cleaning the terminal with a sand paper or the like is prohibited.

­Damaged connector body, exposing the terminals to moisture and dirt, as well as not maintaining proper terminal orientation with the componentor mating connector.

-

Improperly formed or damaged terminals.Check each connector terminal in problem circuits carefully to ensure good contact tension by using the corresponding mating terminal.If contact tension is not enough, reform it to increase contact tension or replace.

-

Poor terminal-to-wire connection.Check each wire harness in problem circuits for poor connection by shaking it by hand lightly. If any abnormal condition is found, repair orreplace.

- Wire insulation which is rubbed through, causing an intermittent short as the bare area touches other wiring or parts of the vehicle.

-

Wiring broken inside the insulation. This condition could cause continuity check to show a good circuit, but if only 1 or 2 strands of amulti-strand-type wire are intact, resistance could be far too high.If any abnormality is found, repair or replace.

The firstsymbol represents the base color of the wire ("GRN" in the figure) and the second symbol represents the color of the stripe (YEL" in the figure).

Keyless Entry Module: Diagnostic Aids

Electrical Circuit Inspection Procedure

While there are various electrical circuit inspection methods, described here is a general method to check its open and short circuit by using an ohmmeterand a voltmeter.

OPEN CIRCUIT CHECK

Possible causes for the open circuit are as follows. As the cause is in the connector or terminal in many cases, they need to be checked particularlycarefully.

- Loose connection of connector

- Poor contact of terminal (due to dirt, corrosion or rust on it, poor contact tension, entry of foreign object etc.)

- Wire harness being open

When checking system circuits including an electronic control unit such as ECM, TCM, ABS control module, etc., it is important to perform carefulcheck, starting with items which are easier to check.

1. Disconnect negative (-) cable from battery2. Check each connector at both ends of the circuit being checked for loose connection. Also check lock condition of connector if equipped with
connector lock.

3. Using a test male terminal, check both terminals of the circuit being checked for contact tension of its female terminal. Check each terminal
visually for poor contact (possibly caused by dirt, corrosion, rust entry of foreign object, etc.). At the same time, check to make sure that eachterminal is locked in the connector fully.

4. Using continuity check or voltage check the following procedure, check the wire harness for open circuit and poor connection with its terminals.
Locate abnormality, if any.

CONTINUITY CHECK

1. Measure resistance between connector terminals at both ends of the circuit being checked (between A-1 and C-1 in the figure). If no continuity is
indicated (infinity or over limit), that means that the circuit is open between terminals A-1 and C-1.

2. Disconnect the connector included in the circuit (connector-B in the figure) and measure resistance between terminals A-1 and B-1.

If no continuity is indicated, that means that the circuit is open between terminals A-1 and B-1. If continuity is indicated, there is an open circuitbetween terminals B-1 and C-1 or an abnormality in connector-B.

VOLTAGE CHECK

If voltage is supplied to the circuit being checked, voltage check can be used as circuit check.

1. With all connectors connected and voltage applied to the circuit being checked, measure voltage between each terminal and body ground.
a. If measurements were taken as shown in the figure and results were as listed below, it means that the circuit is open between terminals B-1 and

A-1.

b. Also, if measured values were as listed below, it means that there is a resistance (abnormality) of such level that corresponds to the voltage

drop in the circuit between terminals A-1 and B-1.

5 V 5 V... 2 V

Voltage between:C-1 and body ground : Approx. B-1 and body ground : Approx. voltage dropA-1 and body ground : Approx. voltage drop3 V... 2 V

SHORT CIRCUIT CHECK (WIRE HARNESS TO GROUND)

5 V

Voltage between:C-1 and body ground : Approx. B-1 and body ground : Approx. A-1 and body ground : 5 V 0 V

1. Disconnect negative (-) cable at battery.2. Disconnect connectors at both ends of the circuit to be checked.

If the circuit to be checked is connected to other parts (1), disconnect all connectors of those parts. Otherwise, diagnosis will be misled.NOTE:

3. Measure resistance between terminal at one end of circuit (A-1 terminal in the figure) and body ground. If continuity is indicated, it means that
there is a short to ground between terminals A-1 and C-1 of the circuit.

4. Disconnect the connector included in circuit (connector B) and measure resistance between A-1 and body ground. If continuity is indicated, it
means that the circuit is shorted to the ground between terminals A-2 and B-1.

Intermittent and Poor Connection

Most intermittent are caused by faulty electrical connections or wiring, although a sticking relay or solenoid can occasionally be at fault. When checkingit for proper connection, perform careful check of suspect circuits for:

- Poor mating of connector halves, or terminals not fully seated in the connector body (backed out).

­Dirt or corrosion on the terminals. The terminals must be clean and free of any foreign material which could impede proper terminal contact.However, cleaning the terminal with a sand paper or the like is prohibited.

­Damaged connector body, exposing the terminals to moisture and dirt, as well as not maintaining proper terminal orientation with the componentor mating connector.

-

Improperly formed or damaged terminals.Check each connector terminal in problem circuits carefully to ensure good contact tension by using the corresponding mating terminal.If contact tension is not enough, reform it to increase contact tension or replace.

-

Poor terminal-to-wire connection.Check each wire harness in problem circuits for poor connection by shaking it by hand lightly. If any abnormal condition is found, repair orreplace.

- Wire insulation which is rubbed through, causing an intermittent short as the bare area touches other wiring or parts of the vehicle.

-

Wiring broken inside the insulation. This condition could cause continuity check to show a good circuit, but if only 1 or 2 strands of amulti-strand-type wire are intact, resistance could be far too high.If any abnormality is found, repair or replace.
