Control Module Self-Test

WARNING: This page is about a different car, the 1989 Ford Pickup, 1989 Ford Cab & Chassis, and 1989 Ford Bronco. However, it is still accessible from the selected car via links, so may be relevant.
  1. To perform electronic control module self-test, remove the 5-wire connector and the 8-wire connector from the module. Turn ignition switch to "RUN" position.
  2. Activate the self-test switch and note result. A flashing indicator light indicates control module is okay. A steady indicator light indicates control module is inoperative and must be replaced.
