Intermittent Codes

If fault code (message) is intermittent and malfunction is not present, problem may not be located while performing diagnostic tests. In this case, stored code can only suggest an area to inspect. If following fault codes occur, even if set intermittently, replace ACM.

• ACM ACCELEROMETER
• ACM OUTPUT DRIVER
• ACM INTERNAL DIAGNOSTIC #1
• ACM INTERNAL DIAGNOSTIC #2
• ACM STORED ENERGY

If any other intermittent codes set, check for loose or corroded connections, damaged components, and damaged wiring. If no obvious problems are found, erase stored codes. With ignition on, wiggle wiring harness and connectors. Recheck for codes periodically as you work through system. This procedure may uncover a difficult problem to locate.
