Reference:

Date:
February 9, 2001

2000-2001 ALTIMA REMOTES DO NOT WORK DURING
RADIATOR COOLING FAN OPERATION

APPLIED VEHICLES:
2000-2001 Altima (L30)

SERVICE INFORMATION

If the multi remote controller (key fob)

^ does not lock or unlock the doors or

^ has reduced range or

^ operates intermittently

when the radiator fans are operating after turning the engine off,
the cause may be electrical noise. Such "noise" can be caused by
operation of the radiator cooling tans and could affect the range of
the remote controllers under some circumstances.

Should this condition occur, use the service procedure in this bulletin
to confirm the condition exists and install the sub-harnesses listed
in the PARTS INFORMATION section of this bulletin to resolve the incident.

SERVICE PROCEDURE

Confirmation Test:

1. Turn the radiator cooling fans "ON" "LOW" using CONSULT-II:

^ Connect CONSULT-II to the vehicle.

^ Turn the ignition switch "ON".

^ Press "START" and select "ENGINE".

^ Press "ACTIVE TEST".

^ Press "COOLING FAN".

^ Press "START".

^ Select "LOW" speed.

NOTE:
To prevent the possibility of electrical interference with the Smart Entrance Control Unit (SECU), roll the front window on the driver's side part way down, exit the vehicle, feed the CONSULT-II unit through the open window, and place the unit on the vehicle's roof.

CAUTION:
To avoid damaging the vehicle's paint, place a clean, soft fender cover or equivalent material under the CONSULT-II unit before placing it on the roof. Take care not to let the CONSULT-II unit fall from the roof of the vehicle.

2. Walk 20 feet from the back of the vehicle and press the remote lock and unlock buttons.

3. Confirm the remote will not lock or unlock the doors by verifying the hazard lights do not flash twice.

4. Turn the cooling fans "OFF" using CONSULT-II.

5. Turn CONSULT-II and the vehicle's ignition switch "OFF".

6. Proceed to the Repair Procedure, below.

Repair Procedure:





1. Disconnect the engine room harness connector from radiator cooling fan connectors E8 and E9 (see Figure 1).

2. Install one sub-harness between the engine room harness connector and cooling fan connector E8 (see Figure 1).

3. Install a second sub-harness between the engine room harness connector and cooling fan connector E9 (see Figure 1).

NOTE:
During installation steps 2 and 3 above, securely engage and lock cooling fan connectors E8 and E9 to the engine room harness and new sub-harness connectors. Failure to do so may cause the ECM to display diagnostic trouble codes.

4. Test that the remote door lock/unlock functions properly by repeating the Confirmation Test (the hazard lights should flash twice when the lock/unlock buttons are pushed).

NOTE:
Ensure the following steps are taken when repeating the Confirmation Test:

^ Check both "HIGH" and "LOW" fan speeds.

^ Confirm both cooling fans are working by opening the hood and visually verifying their operation.

^ Make sure CONSULT-II is placed on the vehicle's roof during testing to prevent the possibility of electrical interference with the Smart Entrance Control Unit (SECU).

CAUTION:
To avoid damaging the vehicle's paint, place a clean, soft fender cover or equivalent material under the CONSULT-II unit before placing it on the roof. Take care not to let the CONSULT-II unit fall from the roof of the vehicle.
