On-Demand Self Test

On-Demand Self-Test
The On-Demand Self-Test option is used to verify that no electrical concerns exist with the air bag SRS. Upon entering the self-test, the air bag control module will make an electrical check of each electrical component in the system. If a concern is detected, a DTC is displayed on the diagnostic tool with a brief description of the DTC. Concerns detected during the self-test are not stored in memory, unless the same concern was also detected during normal vehicle operation. The self-test should always be run after any repair to verify that the repair was successful.

To run the On-Demand Self-Test, follow these steps:
1. Connect the diagnostic tool to the DLC.
2. Turn the ignition switch to position II.
3. Select the MODEL YEAR and VEHICLE.
4. Select DIAGNOSTIC DATA LINK.
5. Select RCM.
6. Select DIAGNOSTIC TEST MODES.
7. Select ON-DEMAND SELF-TEST.
8. Press START.
9. Press TRIGGER. The air bag control module will run the On-Demand Self-Test and display On-Demand DTCs (reflecting hard system concerns) on the screen.
