Relay - Part number 92107897
BCM Failure - Some BCM's may suffer from water damage. The retaining bolt in the Right side of the Fire wall panel may be insufficiently sealed. If water leaks past this bolt, connector D of the BCM can be affected. The firewall reatining bolt should be checked for tightness, and resealed with a sealer such as silicone RTV 732 (92140051).
Traction Control - The Traction control warning lamp and engine check lamp may illuminate in Some VX V6's, due to oversensitive PCM calibration. GMH have found there was some software timing issues in the PCM (Powertrain Control Module), and revised PCM software was introduced early 2001.
Remote Key Readers - On the 25th of May 2001 a Full Circle keyless entry system was introduced. The Full Circle key readers may separate or fall apart. A revised reader was introduced on the 25th July 2001.
GEN III O2 Sensors - Some Gen III Automatics will experience water contamination on the LH O2 sensor plug, which can cause O2 sensor faults. This problem may be a result of the A/C drain tube in the transmission tunnel, as it is in the same proximity as the O2 sensor harness. A bracket was introduced for the O2 sensor connector, that will position it away from the A/C drain tube.
