Self-Diagnostic System: Notes

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

Air bag system is monitored by Occupant Restraint Controller (ORC). ORC monitors internal and external air bag system electrical circuits to determine system readiness. When a monitored system is determined out of range, ORC will set both active and stored Diagnostic Trouble Codes (DTCs) or fault messages to aid in diagnosing system problems.

If more than one code exists, diagnostic priority should be given to active codes. Each DTC is diagnosed by following a specific testing procedure. Diagnostic test contain step-by-step instructions for determining cause of the DTC. It is not necessary to perform all diagnostic tests to diagnose an individual code. Always begin by reading DTCs with DRBIII. Perform corresponding test to determine system malfunction. See DIAGNOSTIC TROUBLE CODES (DTCS) table.
