# REMOTE KEYLESS ENTRY INOP. (NEW PART RELEASED)

#### SUBJECT: RETAINED ACCESSORY POWER (KP2) AND/OR REMOTE KEYLESS ENTRY (AUO) PERFORMANCE

#### MODELS AFFECTED: 1991 NINETY-EIGHT/ TOURING SEDANS

#### CONDITION:

----------- Some 1991 Ninety-Eight models with option "AUO" (Remote Keyless Entry), may exhibit a problem with the range at which the system will operate. The customer complaint may be that they have to get very close to the vehicle to unlock/lock the door or trunk.

The 1991 Ninety-Eight/Touring Sedan models with option "KP2" (Retained Accessory Power), and option "C97" (Illuminated Entry), may experience a momentary dropout of radio volume or "POP" noise in the radio when the ignition is turned off.

#### CAUSE:

------- The momentary dropout in volume or "POP" noise in the radio when the ignition is turned off and the short range condition of the RKE option is caused by the Remote Accessory Control (RAC) module.

#### CORRECTION:

----------- To correct the short range problem with the Remote Keyless Entry system, replace the remote accessory control module (RAC) with part number 25602654, which is currently available from GMSPO. After replacing the RAC module, the transmitter must be reprogrammed using the following procedure: 1. Turn the ignition switch to off. 2. Jumper the ALDL connector terminal A to G. At this point the dorr locks will lock then unlock. 3. Press the unlock button on the transmitter. At this point the door locks will again lock then unlock. 4. Disconnect the jumper from the ALDL connector.

The new RAc module should provide an average RKE operation of about 45 feet. Range may vary from 15 to 125 feet depending on the direction and transmitter angle.
