SUBJECT: MALFUNCTIONING PASS-KEY RELAY (REPLACE STARTER ENABLE RELAY/CHANGE WIRING)

VEHICLES AFFECTED: 1991-92 "C, E AND K" MODELS

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 "H" cars),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 1991-92 Park Avenue/Ultras built before N1628377, Olds 98 built before N4325328 and Cadillac "C" built before N4260457, also change the wiring as per the procedure.

On LeSabres built before VIN NH436308, Olds VIN NH337131 and N1806991, Pontiac N1231989, also 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.
