Retrieving Diagnostic Trouble Codes
- Turn ignition off. Press and hold all 3 Driver's Position Memory Systems (DPMS) switch buttons simultaneously. Turn ignition on, wait at least one second then release all buttons. After one more second, position setting buttons will blink to indicate DTC.
- If no DTCs are stored, position setting button LEDs will only blink one 3-second long blink. If DTCs are stored, first digit of DTC is indicated by one second blinks. Second digit of DTC is indicated by short (.26 second) blinks. Each DTC is followed by a 3 second pause before any other DTCs are displayed.
- Record all DTCs and see appropriate flow chart to locate cause of problem. See DIAGNOSTIC TROUBLE CODE DEFINITIONS table. Up to 5 DTCs will be stored at once.
