SERVICE INFORMATIONThis bulletin provides information to address the concerns of any 1995,1996 or early 1997 Maxima owner who states their vehicle does not alwaysrespond to the remote switches. This incident is a cycle where a customer cites an inoperative remote switch, the dealer reprograms the remotes and theincident returns for no apparent reason.

Troubleshooting the remote control system per the service manual reveals not problems with the remote batteries, antenna, LCUO5, BCM or wireharness connections.

Such an incident may be caused by the owner jiggling the ignition key after locking the doors. The sequence of these events erases the remote ID codesfrom memory.
There is a countermeasure multi-remote control unit available (which prevents accidental remote ID code erasure) to resolve this incident.

SERVICE PROCEDURE

1. Interview the customer to see if they usually lock the door before starting the car.

2.
Use the 1996 service manual page EL-225 to test the Multi Remote Control System. Perform the six diagnostic tests for symptom: "All functionsof remote control system do not function".

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 (ECCS control module) can detect its 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 its malfunctions with the on-board diagnostic system.

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.

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.

Introduction

The section is 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

Instructions > Page 77

Maxima SE V6-2968cc 3.0L DOHC MFI (VQ30DE) (1997)

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 theowner experiences an electrical incident.

Incident Simulation Tests

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 may notreveal this without disconnecting the connector. If the problem occurs intermittently, perhaps the problem is caused by corrosion. It is a good ideato disconnect, inspect and clean the terminals on related connectors in the system.

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.

Maxima SE V6-2968cc 3.0L DOHC MFI (VQ30DE) (1997)

Tester probe

(DMM)

When probing a connector it is possible to enlarge the contact spring opening. If this occurs it may create an intermittent signal in the circuit.When probing a connector use care not to enlarge the opening. The probe of the Digital Multimeter may not fit into the connector cavity.In such cases make an extension of a "T" pin and probe it from the harness side of the connector. Most DMMs have accessory alligator clips. Slidethese over the probe to allow clipping the "T" pin for a better contact. If you have any difficulty probing a terminal, inspect the terminal. Ensureyou have not accidentally opened the contact spring or pulled a wire loose.

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

^ Connectors not fully be 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. Refer to GROUND INSPECTION. First, check thatthe system is properly grounded. Then, check for loose connection by gently shaking the wiring or components as previously explained. Using thewiring diagrams, inspect the wiring 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.60C (140F)

Freezing

Instructions > Page 79

Maxima SE V6-2968cc 3.0L DOHC MFI (VQ30DE) (1997)

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 his car overnight. Make sure it will get cold enough to demonstratehis 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.

Connector and Terminal Pin Kit

Connector And Terminal Pin Kit

Use the connector and terminal pin kit listed below when replacing connectors or terminals.The connector and terminal pin kit contains some of the most commonly used NISSAN connectors and terminals.

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.

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 the

diagnosis process. Drawing the sketch will also reinforce your working knowledge of the system.

Continuity check method (DMM)

The continuity check is used to find an open in the circuit. The Digital Multimeter set on the resistance function will indicate an opencircuit as over limit (OL, no beep tone or no ohms symbol). Make sure no power is supplied to the checked component. Always start with theDMM 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. It 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.

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.
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 START position. Verify battery voltage at the B+ side of the fuse terminal (one lead on the B+ terminal side ofON

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

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

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 screw or clip.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 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.

Measuring voltage drop - Accumulated method

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 to
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.

Note in the illustration that there is an excessive 4.1 volt drop between the battery and the bulb.

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.

1. Connect the Voltmeter as shown, starting at the battery and working your way around the circuit.2. An usually large voltage drop will indicate a component or wire that needs to be prepared. As you can see the illustration above, the poor

connection causes a drop.4 Volt
