Intermittent Codes
If fault code 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 SAFING SENSOR OPEN, SAFING SENSOR SHORT, INTERNAL DIAGNOSTIC #1, #2, #3, or #4, INTERNAL LAMP DRIVER, LOW STORED ENERGY PASSENGER OR LOW STORED ENERGY DRIVER, AECM ACCELEROMETER, AECM INTERNAL DIAGNOSTIC #1 or #2, or AECM STORED ENERGY fault codes set intermittently, ACM should be replaced.
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.
