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, RCM 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 data link connector (DLC).
2. Turn the ignition switch to the RUN position.
3. Follow the manufacturer's instructions for the diagnostic tool being used.
4. The RCM will run the On-Demand Self Test and display on-demand DTCs (reflecting hard system concerns) on the screen.
