Diagnostic Aids

WARNING: This page is about a different car, the 2004 Pontiac Grand Prix. However, it is still accessible from the selected car via links, so may be relevant.

This table is used for all RAP relay and RAP serial data controlled accessories which remain active after RAP has timed out. The RAP relay system can malfunction separately from the serial data controlled RAP system and the serial data controlled RAP system can malfunction separately from the RAP relay. If multiple accessories are not exhibiting an "On After Time-out" symptom, either on the RAP relay controlled circuit or the serial data controlled circuit or both, the malfunction is in a particular device and not in the RAP control system. Refer to Control Module References in Body Control System.
