Diagnostic Aids

WARNING: This page is about a different car, the 2003 Pontiac Aztek and 2003 Buick Rendezvous. However, it is still accessible from the selected car via links, so may be relevant.

The IPC will store the code as current only as long as the failure exists. An intermittent failure will be stored as a history DTC B2823.
If DTC B2823 is set only in history, press and release the trip reset switch several times in order to verify the customer concern.
