Diagnostic Trouble Codes

Airbag diagnostic trouble codes consist of active and stored codes. If more than one code exists, diagnostic priority should be given to the active codes. Each diagnostic trouble code is diagnosed by following a specific testing procedure. The diagnostic test procedures contain step-by-step instructions for determining the cause of the trouble codes. It is not necessary to perform all of the tests in this service information to diagnose an individual code. Always begin by reading the diagnostic trouble codes using the DRBIII®. Active diagnostic trouble codes for the airbag system are not permanent and will change the moment the reason for the code is corrected. In certain test procedures within this service information, diagnostic trouble codes are used as a diagnostic tool.
