REMOTE KEYLESS ENTRY OPERATES W/O BEING ACTIVATED

SUBJECT: INSTALL NEW REMOTE KEYLESS ENTRY (RKE) RECEIVER MODULE

MODELS/YEARS: 1992 TORONADO/TROFEO'

Some 1992 Toronado, and Trofeo models equipped with the Remote Keyless Entry (RKE) system (option code AUO) may exhibit a condition where the trunk may open when the vehicle is in park or the door locks may unlock without activation of the transmitter. This condition may occur more often in high humidity climates. A new RKE receiver module, which is less susceptible to humidity, has improved circuit board solder and assembly processes, has been released.

The following service procedure should be used to correct these conditions:

1. Install a new RKE receiver module, P/N 22139398 which is currently available from GMSPO. Refer to service manual, Section 9K, for receiver replacement procedure.

2. Reprogram RKE system using the original transmitters. Refer to service manual, Section 9K, for programming procedure.

General Motors bulletins are intended for use by professional technicians, not a "do-it-yourselfer". They are written to inform those technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions and know-how to do a job properly and safely. If a condition is described, do not assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See a General Motors dealer servicing your brand of General Motors vehicle for information on whether your vehicle may benefit from the information.
