On-Demand Self Test

WARNING: This page is about a different car, the 2006 Mercury Milan, 2006 Lincoln Zephyr, and 2006 Ford Fusion. 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 SRS. Upon entering the self-test, the restraints control module (RCM) will make an electrical check of each electrical component in the system. When entering the self-test for the occupant classification sensor (OCS) module, an electrical check is made of the OCS system components and circuits as well as functional checks of the OCS 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:

Connect the diagnostic tool to the DLC.
Turn the ignition switch to the ON position.
Follow the manufacturer's instructions for the diagnostic tool being used.
The module will run the On-Demand Self Test and display on-demand DTCs (reflecting hard system concerns) on the diagnostic tool.
