DETECTABLE LINES AND NON-DETECTABLE LINES

In some wiring diagrams, two kinds of lines, representing wires with different weight are used.

^

A line with regular weight (wider line) represents a "detectable line for DTC (Diagnostic Trouble Code)". A "detectable line for DTC" is a circuitin which (ECM) (Engine control module) can detect malfunctions with the on-board diagnostic system.

^

A line with less weight (thinner line) represents a "non-detectable line for DTC". A "non-detectable line for DTC" is a circuit in which ECMcannot detect malfunctions with the on-board diagnostic system.

MULTIPLE SWITCH

The continuity of multiple switch is described in two ways as shown below.

^ The switch chart is used in schematic diagrams.
^ The switch diagram is used in wiring diagrams.

FINDING ELECTRICAL DIAGRAMS

Electrical diagrams can be found by selecting the specific component or by selecting diagrams at vehicle level.

REFERENCED DIAGRAMS

In many instances electrical diagrams will refer you to another electrical diagram to complete the circuit. These referenced electrical diagrams can befound at vehicle level under "Diagrams".

Introduction

In general, testing electrical circuits is an easy task if it is approached in a logical and organized method. Before beginning, it is important to have allavailable information on the system to be tested. Also, get a thorough understanding of system operation. Then you will be able to use the appropriateequipment and follow the correct test procedure.You may have to simulate vehicle vibrations while testing electrical components. Gently shake the wiring harness or electrical component to do this.
OPEN A circuit is open when there is no continuity through a section of the circuit.

SHORT There are two types of shorts.

^ SHORT CIRCUIT When a circuit contacts another circuit and causes the normal resistance to change.
^ SHORT TO GROUND When a circuit contacts a ground source and grounds the circuit.

Refer to "How to Probe Terminal" to probe or check terminal.NOTE:

Testing For "OPENS" In the Circuit

Before you begin to diagnose and test the system, you should rough sketch a schematic of the system. This will help you to logically walk through thediagnosis process. Drawing the sketch will also reinforce your working knowledge of the system.

Continuity check method Digital Multimeter (DMM)

> Page 34

Quest Minivan GLE V6-3.3L (VG33E) (1999)

The continuity check is used to find an open in the circuit. The set on the resistance function will indicate an opencircuit as over limit (no beep tone or no ohms symbol). Make sure to always start with the DMM at the highest resistance level.To help in understanding the diagnosis of open circuits please refer to the image above.1. Disconnect the battery negative cable.2. Start at one end of the circuit and work your way to the other end (At the fuse block in this example).3. Connect one probe of the DMM to the fuse block terminal on the load side.4. Connect the other probe to the fuse block (power) side of SW1. Little or no resistance will indicate that portion of the circuit has good

continuity. If there were an open in the circuit, the DMM would indicate an over limit or infinite resistance condition (point A).

5. Connect the probes between SW1 and the relay. Little or no resistance will indicate that portion of the circuit has good continuity. If there were
an open in the circuit, the DMM would indicate an over limit or infinite resistance condition (point B).

6. Connect the probes between the relay and the solenoid. Little or no resistance will indicate that portion of the circuit has good continuity. If
there were an open in the circuit, the DMM would indicate an over limit or infinite resistance condition (point C).

Any circuit can be diagnosed using the approach in the above example.

Voltage check method

To help in understanding the diagnosis of open circuits please refer to the previous image.In any powered circuit, an open can be found by methodically checking the system for voltage. This is done by switching the DMM to the voltagefunction.1. Connect one probe of the DMM to a known good ground.2. Begin probing at one end of the circuit and work your way to the other end.3. With SW1 open, probe at SW1 to check for voltage.

Voltage: Open is further down the circuit than SW1.No Voltage: Open is between fuse block and SW1 (point A).

4. Close SW1 and probe at relay.
Voltage: Open is further down the circuit than the relay.No Voltage: Open is between SW1 and relay (point B).

5. Close the relay and probe at the solenoid.
Voltage: Open is further down the circuit than the solenoid.No Voltage: Open is between relay and solenoid (point C).

Any powered circuit can be diagnosed using the approach in the above example.

Testing For "SHORTS" In the Circuit

Resistance check method

Continuity: Short is between fuse terminal and SW1 (point A).No continuity: Short is further down the circuit than SW1.

5. Close SW1 and disconnect the relay. Put probes at the load side of fuse terminal and a known good ground. Then, check for continuity.
Continuity: Short is between SW1 and the relay (point B).No continuity: Short is further down the circuit than the relay.

6. Close SW1 and jump the relay contacts with jumper wire. Put probes at the load side of fuse terminal and a known good ground. Then, check

for continuity.Continuity: Short is between relay and solenoid (point C).No continuity: Check solenoid, retrace steps.

Voltage Check Method

1. Remove the blown fuse and disconnect all loads (i.e., SW1 open, relay disconnected and solenoid disconnected) powered through the fuse.2. Turn the ignition key to the or position. Verify battery voltage at the B+ side of the fuse terminal (one lead on the B+ terminalON START

side of the fuse block and one lead on a known good ground).

3. With SW1 open and the DMM leads across both fuse terminals, check for voltage.

1. Disconnect the battery negative cable and remove the blown fuse.2. Disconnect all loads (SW1 open, relay disconnected and solenoid disconnected) powered through the fuse.3. Connect one probe of the ohmmeter to the load side of the fuse terminal. Connect the other probe to a known good ground.4. With SW1 open, check for continuity.

Voltage: Short is between fuse block and SW1 (point A).No voltage: Short is further down the circuit than SW1.

4. With SW1 closed, relay and solenoid disconnected and the DMM leads across both fuse terminals, check for voltage.
Voltage: Short is between SW1 and the relay (point B).No voltage: Short is further down the circuit than the relay.

5. With SW1 closed, relay contacts jumped with fused jumper wire check for voltage.
Voltage: Short is down the circuit of the relay or between the relay and the disconnected solenoid (point C).No voltage: Retrace steps and check power to fuse block.

Ground Inspection

Ground connections are very important to the proper operation of electrical and electronic circuits. Ground connections are often exposed to moisture,dirt and other corrosive elements. The corrosion (rust) can become an unwanted resistance. This unwanted resistance can change the way a circuit works.Electronically controlled circuits are very sensitive to proper grounding. A loose or corroded ground can drastically affect an electronically controlledcircuit. A poor or corroded ground can easily affect the circuit. Even when the ground connection looks clean, there can be a thin film of rust on thesurface. When inspecting a ground connection follow these rules:

1. Remove the ground bolt or screw.2. Inspect all mating surfaces for tarnish, dirt, rust, etc.3. Clean as required to assure good contact.4. Reinstall bolt or screw securely.5. Inspect for "add-on" accessories which may be interfering with the ground circuit.6. If several wires are crimped into one ground eyelet terminal, check for proper crimps. Make sure all of the wires are clean, securely fastened and
providing a good ground path. If multiple wires are cased in one eyelet make sure no ground wires have excess wire insulation.

Voltage Drop Tests

0 Ohms

Voltage drop tests are often used to find components or circuits which have excessive resistance. A voltage drop in a circuit is caused by a resistancewhen the circuit is in operation.Check the wire in the illustration. When measuring resistance with ohmmeter, contact by a single strand of wire will give reading of . This wouldindicate a good circuit. When the circuit operates, this single strand of wire is not able to carry the current. The single strand will have a high resistanceto the current. This will be picked up as a slight voltage drop.Unwanted resistance can be caused by many situations:

^ Undersized wiring (single strand example)
^ Corrosion on switch contacts
^ Loose wire connections or splices.

If repairs are needed always use wire that is of the same or larger gauge.

1. Connect the voltmeter across the connector or part of the circuit you want to check. The positive lead of the voltmeter should be closer toMeasuring voltage drop - Accumulated method

power and negative lead closer to ground.

2. Operate the circuit.3. The voltmeter will indicate how many volts are being used to "push" current through that part of the circuit.

In the illustration that there is an excessive drop between the battery and the bulb.NOTE: 4.1 Volt

Measuring voltage drop - Step by step

The step by step method is most useful for isolating excessive drops in low voltage systems (such as computer controlled systems).Circuits in the computer controlled system operate on very low amperage.The (Computer controlled) system operations can be adversely affected by any variation in resistance in the system. Such resistance variation maybe caused by poor connection, improper installation, improper wire gauge or corrosion.The step by step voltage drop test can identify a component or wire with too much resistance.

Introduction

Sometimes the symptom is not present when the vehicle is brought in for service. If possible, re-create the conditions present at the time of the incident.Doing so may help avoid a No Trouble Found Diagnosis. The following section illustrates ways to simulate the conditions/environment under which thevehicle experiences an electrical incident.
The tests are broken into the six following topics;

^ Vehicle vibration
^ Heat sensitive
^ Freezing
^ Water intrusion
^ Electrical load
^ Cold or hot start up

Get a thorough description of the incident from the customer. It is important for simulating the conditions of the problem.

Vehicle Vibration

The problem may occur or become worse while driving on a rough road or when engine is vibrating (idle with A/C on). In such a case, you will want tocheck for a vibration related condition.

Connectors & harness

Determine which connectors and wiring harness would affect the electrical system you are inspecting. Gently shake each connector and harnesswhile monitoring the system for the incident you are trying to duplicate. This test may indicate a loose or poor electrical connection.

HINT:

Connectors can be exposed to moisture. It is possible to get a thin film of corrosion on the connector terminals. A visual inspection maynot reveal this without disconnecting the connector. If the problem occurs intermittently, perhaps the problem is caused by corrosion. It is a goodidea to disconnect, inspect and clean the terminals on related connectors in the system.

Quest Minivan GLE V6-3.3L (VG33E) (1999)

Sensors & relays

Gently apply a slight vibration to sensors and relays in the system you are inspecting.This test may indicate a loose or poorly mounted sensor or relay.

Engine Compartment

There are several reasons a vehicle or engine vibration could cause an electrical complaint. Some of the things to check for are:^

Connectors not fully seated.
^ Wiring harness not long enough and is being stressed due to engine vibrations or rocking.
^ Wires laying across brackets or moving components.
^ Loose, dirty or corroded ground wires.
^ Wires routed too close to hot components.

To inspect components under the hood, start by verifying the integrity of ground connections. First, check that the system is properly grounded.Then, check for loose connection by gently shaking the wiring or components as previously explained. Using the wiring diagrams, inspect thewiring for continuity.

Behind the instrument panel

An improperly routed or improperly clamped harness can become pinched during accessory installation. Vehicle vibration can aggravate a harnesswhich is routed along a bracket or near a screw.

Under Seating areas

An unclamped or loose harness can cause wiring to be pinched by seat components (such as slide guides) during vehicle vibration. If the wiringruns under seating areas, inspect wire routing for possible damage or pinching.

Heat Sensitive

The owner's problem may occur during hot weather or after car has sat for a short time. In such cases you will want to check for a heat sensitivecondition.To determine if an electrical component is heat sensitive, heat the component with a heat gun or equivalent.Do not heat components above . If incident occurs while heating the unit, either replace or properly insulate the component.60 C (140 F)

Freezing

> Relays and Modules > Relays and Modules - Body and Frame > Power Seat Control Module > Component Information > Diagrams > Diagram Information and Instructions

> Page 39

Quest Minivan GLE V6-3.3L (VG33E) (1999)

The customer may indicate the incident goes away after the car warms up (winter time). The cause could be related to water freezing somewhere in thewiring/electrical system.There are two methods to check for this. The first is to arrange for the owner to leave the car overnight. Make sure it will get cold enough to demonstratethe complaint. Leave the car parked outside overnight. In the morning, do a quick and thorough diagnosis of those electrical components which could beaffected.The second method is to put the suspect component into a freezer long enough for any water to freeze. Reinstall the part into the car and check for thereoccurrence of the incident. If it occurs, repair or replace the component.

Water Intrusion

The incident may occur only during high humidity or in rainy/snowy weather. In such cases the incident could be caused by water intrusion on anelectrical part. This can be simulated by soaking the car or running it through a car wash.Do not spray water directly on any electrical components.

Electrical Load

The incident may be electrical load sensitive. Perform diagnosis with all accessories (including A/C, rear window defogger, radio, fog lamps) turned on.

Cold or Hot Start Up

On some occasions, an electrical incident may occur only when the car is started cold. Or it may occur when the car is restarted hot shortly after beingturned off. In these cases you may have to keep the car overnight to make a proper diagnosis.

1. Assemble a male terminal and approx. of wire. 10 cm (3.9 in)

Use a male terminal which matches the female terminal.NOTE:

2. Disconnect the suspected faulty connector and hold it terminal side up.

3. While holding the wire of the male terminal, try to insert the male terminal into the female terminal.

Do not force the male terminal into the female terminal with your hands.NOTE:

4. While moving the connector, check whether the male terminal can be easily inserted or not.

^ If the male terminal can be easily inserted into the female terminal, replace the female terminal.

How to Probe Connectors

digitalmultimeter (DMM)

Connector damage and an intermittent connection can result from improperly probing of the connector during circuit checks. The probe of a may not correctly fit the connector cavity. To correctly probe the connector, follow the procedures below using a "T" pin. For thebest contact grasp the "T" pin using an alligator clip.

Probing From Harness Side

Standard type (not waterproof type) connector should be probed from harness side with "T" pin.

NOTE:

^ If the connector has a rear cover such as an ECM connector, remove the rear cover before probing the terminal.
^ Do not probe waterproof connector from harness side. Damage to the seal between wire and connector may result.

Female Terminal

There is a small notch above each female terminal. Probe each terminal with the "T" pin through the notch.

: Do not insert any object other than the same type male terminal into female terminal.NOTE

^

Some connectors do not have a notch above each terminal. To probe each terminal, remove the connector retainer to make contact space forprobing.

Male Terminal

Carefully probe the contact surface of each terminal using a "T" pin.

Do not bend terminal.NOTE:

If water enters the connector, it can short interior circuits. This may lead to intermittent problems.Check the following items to maintain the original waterproof characteristics.

^RUBBER SEAL INSPECTION

Most waterproof connectors are provided with a rubber seal between the male and female connectors. If the seal is missing, the waterproofperformance may not meet specifications.

^

The rubber seal may come off when connectors are disconnected. Whenever connectors are reconnected, make sure the rubber seal is properlyinstalled on either side of male or female connector.

The wire seal must be installed on the wire insertion area of a waterproof connector. Be sure that the seal is installed properly.WIRE SEAL INSPECTION

Terminal Lock Inspection

Check for unlocked terminals by pulling wire at the end of connector. An unlocked terminal may create intermittent signals in the circuit.

Power Seat Control Module: Description and Operation
OPERATION

Automatic drive positioner allows automatic positioning of driver seat, LH and RH door mirror to two programmable positions using the memory setswitch located on the drivers door and multi-remote controller. Driver's seat can be adjusted for sliding, reclining and cushion height.

MEMORY POSITION OPERATION

Automatic drive positioner has the following three functions

^ Memory set switch operation (Memorized position can be set corresponding to memory switch operation.)
^ Multi-remote controller operation (Memorized position can be set by unlocking driver's door with multi-remote controller.)
^ Auto back operation (Driver's seat fully rearward and down for easy access.)

NOTE:

^

As a safety feature, the memory positioning operation is permitted to operate only if the park/neutral position (PNP) switch is in the park or neutralposition. If the memory position operation is activated and PNP switch is moved from park or neutral position, the memory position operation willbe halted.

^ If either memory position switch is pressed after motion has started, all motion will immediately stop.
^ If a manual control switch is pressed, memory operation will be cancelled.
^

All seat and mirror sensors shall be monitored for validity. If any sensor is seen to be out of range, no motion shall be performed for that axisduring memory recall. Invalid sensors do not affect manual operation.

^

Up to 2 seat axes will move simultaneously during memory position operation. All mirror axes may move simultaneously during memory positionoperation.

Memory Set Switch Operation

1. Push and release memory set switch 1 or 2 with ignition switch in or ACC position. (LED indicator on the memory set switch will turn onOFF
until memory set switch is released or have passed.)10 seconds

2. Driver's seat, LH and RH door mirrors will move to the memorized position.

Multi-remote Controller Operation

1. Unlock driver's door with multi-remote controller. (Automatic positioning signal will be sent to memory seat and mirror control unit from smart
entrance control unit.)

2. Driver's seat, LH and RH door mirrors will move to the memorized position.
