Self Test/On-Demand
WARNING: This page is about a different car, the 2009 Mercury Grand Marquis and 2009 Ford Crown Victoria. 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 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:
- Connect the scan tool to the Data Link Connector (DLC).
- Turn the ignition to the ON position.
- Follow the manufacturer's instructions for the scan tool being used.
- Select Self Test.
- Select RCM.
- The module will run the self-test and display on-demand (reflecting hard system concerns) and continuous memory (historic) DTCs on the scan tool.
