Engine Stalls, Security Lamp Illuminated, DTCs P1626, P1629, B2955, B2960, B3022, B3024, B3025 Set (Replace Theft Deterrent Control Module)

Some customers may comment that the vehicle starts then stalls and the security lamp is illuminated. These symptoms may be intermittent and after several start attempts, the vehicle may stay running. Upon investigation, the technician may find DTCs P1626, P1629, B2955, B2960, B3022, B3023, B3024, B3025 set and the PASS-KEY III® fuse blown.

This condition may be caused by either a chafed wire in the theft deterrent module wiring harness or an electrical interference within the theft deterrent module not allowing the fuel enable signal to be detected.

Replace the theft deterrent module with P/N 10335045 and reroute the module wiring harness to a new location using the procedure listed below.

1. Replace the theft deterrent module. Refer to the Theft Deterrent Control Module Replacement procedure in the Theft Deterrent sub-section of the Service Manual.



2. Reroute the module harness (1) on the outside of the steering column channel and tie strap the lower portion to the larger ignition bundle.
3. Replace the tie strap removed from the tilt head during disassembly. Secure the new strap in the hole in the tilt mechanism and around the module wires and the ignition and SIR wires, but below the tie strap located on the SIR wires.

Parts are expected to be available 11/11/02 from GMSPO.
