Self Test/On-Demand
WARNING: This page is about a different car, the 2007 Lincoln MKX and 2007 Ford Edge. However, it is still accessible from the selected car via links, so may be relevant.
The on-demand Self Test option is used to verify that no electrical concerns exist with the air bag supplemental restraint system (SRS). Upon entering the self-test, the restraints control module (RCM) and the occupant classification system module (OCSM) 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 diagnostic trouble code (DTC). The self-test should always be carried out after any repair to verify that the repair was successful.
To run the on-demand Self Test, follow these steps:
- Connect the scan tool to the data link connector (DLC).
- Turn the ignition switch to the ON position.
- Follow the manufacturer's instructions for the scan tool being used.
- Select RCM or OCSM.
- Select Self-Test.
- The module will run the self-test and display on-demand (reflecting hard system concerns) and continuous memory (historic) DTCs on the scan tool.
