RKE Poor Transmitter Range

Subject:Remote Keyless Entry (RKE) Poor Transmitter Range -- Rotate Position of Body Control Module (BCM) 180° in Vehicle

Models:2000-2001 Saturn L-Series vehicles equipped with remote keyless entry (RPO RFA) up to and including VIN 1Y570729


Condition:

Some customers may comment on poor RKE range while trying to lock or unlock the vehicle.

Cause:

This condition may be caused by orientation of the internal antenna within the BCM.

Correction:

Verify the condition and rotate the BCM in the vehicle 180°.

Service Procedure: Remote Keyless Entry (RKE) Range Performance Check.
  1. Move the vehicle outside and as far away as possible from objects that could interfere with RKE function.
  2. While standing directly behind the vehicle on the drivers side at a distance of 15 feet, function test the features on the RKE.
    3. • If the vehicle locks and unlocks, the RKE system is OK. However, the RKE range performance will be increased when the BCM is rotated. Proceed to BCM Rotation Procedure in this bulletin to rotate the BCM.
    • If the vehicle does not lock and unlock, move closer to the vehicle while functioning the RKE transmitter.
       - If the RKE features operate when moved closer to the vehicle, then it will be necessary to rotate the BCM. Proceed to BCM Rotation Procedure in this bulletin to rotate the BCM.
       - If the RKE features do not operate, refer to Remote Keyless Entry (RKE) System Check procedure located in the Locks and Security section of the 2000-2001 L-Series Body Electrical Volume II Service Manual.
