Diagnostic Trouble Codes: Notes

Airbag diagnostic trouble codes (DTC) consist of active and stored codes. If more than one DTC exists, diagnostic priority should be given to the active code(s). Each DTC is diagnosed by following a specific testing procedure. The diagnostic test procedures contain step-by-step instructions for determining the cause of the DTC. It is not necessary to perform all of the tests in this service information to diagnose an individual DTC.

Always begin by reading the DTC's using the DRBIII®. If more than one code exists, diagnostic priority should be given to active code(s).

Active DTC's for the airbag system are not permanent and will change the moment the cause of the code is corrected. In certain test procedures within this service information, DTC's are used as a diagnostic tool.
