On-Demand Self-Test
WARNING: This page is about a different car, the 2002 Ford Windstar. However, it is still accessible from the selected car via links, so may be relevant.
On-demand self-test option is used to verify that no electrical concerns exist with air bag system. Upon entering self-test, Restraints Control Module (RCM) will make an electrical check of each air bag system electrical component. If a fault is detected, a Diagnostic Trouble Code (DTC) is displayed on scan tool, with brief description of DTC. Faults detected during self-test are not stored in memory, unless same fault was also detected during normal vehicle operation. Self-test should always be run after any repair to verify that repair was successful.
To run on-demand self-test:
- Connect scan tool to Data Link Connector (DLC), located under instrument panel.
- Turn ignition switch to RUN position.
- Follow manufacturer's instructions for the scan tool being used.
- RCM will run on-demand self-test and display on-demand DTCs on tester screen.
