Diagnosis & Testing: Self-Diagnostics

The system readiness indicator light (AIR BAG warning light) is used in diagnosing malfunctions or faults in the SRS. A fault code will be displayed when the ignition switch is in the RUN position and the diagnostic monitor detects a system fault. Certain faults may not be displayed until approximately 30 seconds after ignition switch has been turned to RUN position. This is the amount of time required for diagnostic monitor to test and verify all system faults.

The 2 digit fault codes are produced by a series of AIR BAG warning light flashes. For example, a fault Code 32 will be displayed in the following manner: flash flash flash, one second pause, flash flash, 3 second pause, then the cycle would repeat.

The coded fault feature is prioritized so that if 2 or more different faults occur at the same time, the highest priority fault indication will be shown until corrected using appropriate circuit test procedures. See FAULT CODE PRIORITIES table. Identify fault code and perform CIRCUIT TEST specified. Once the higher priority fault is corrected, check AIR BAG warning light to see if other fault exists. See TESTING - SYSTEM OPERATION CHECK  .

If a system fault exists and AIR BAG warning light is malfunctioning, a series of 5 sets of 5 beeps will be heard indicating service is needed. The number of beeps does not indicate a fault code. See CIRCUIT TEST A  .
