Bulletin: 92-8-14

Date: Jan. '92

Ref. No.: 92-89-8

Corp. Ref. No.: 108148


SUBJECT: MALFUNCTIONING PASS-KEY RELAY

MODELS AFFECTED: 1991-92 PARK AVENUE/ULTRA
1992 LESABRE
1990-91 RIVIERA/REATTA


CONDITION:

An intermittent no crank condition may be caused by a malfunctioning Pass-Key Relay. The security light will come on for two seconds (5 on LeSabre), and then go out, when attempting to start the vehicle. The vehicle, however, will not enable the starter.

SERVICE PROCEDURE:

On all vehicles, replace the starter enable relay with Part Number 25609047. Refer to the appropriate service manual for location of the starter enable relay.

On all 1991 Park Avenue/Ultras and 1992 Park Avenue/Ultras built before N1628377, also change the wiring as per the procedure.

On LeSabres built before VIN NH436308, change the wiring as follows:





1. Cut circuit 439 (pnk/blk) wire far enough from the relay connector to allow for splicing. Strip the relay side of the wire for splicing. Tape back the harness side of circuit 439. Refer to Figure 1 for wiring modification schematic.

2. Cut circuit 5 (yellow wire) far enough from the relay connector to allow for splicing.

3. Splice the three wires (both circuit 5 wires and the circuit 439 wire to the relay) together with a splice clip, part number 1839906, which can be found in terminal repair kit tool J-38125. Follow the procedure for "splicing copper wire using splice clips" in the service manual.

Parts are currently available from GMSPO.
