Self Test/On-Demand

SELF TEST/ON-DEMAND

The on-demand Self Test option is used to verify that no electrical concerns exist with the supplemental restraint system (SRS). Upon entering the self-test, the restraints control module (RCM) will make an electrical check of each electrical component in the system. If a concern is detected, a DTC is displayed on the scan tool with a brief description of the DTC. 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 scan tool to the data link connector (DLC).
2. Turn the ignition switch to the ON position.
3. Follow the manufacturer's instructions for the scan tool being used.
4. Select Self Test.
5. Select RCM.
6. The module will run the self-test and display on-demand (reflecting hard system concerns) and continuous memory (historic) DTCs on the scan tool.
