Clearing Codes/Pcm Reset Procedure
NOTE:
Some models have an anti-theft code built into the radio circuit. Clearing codes cancels clock and radio settings; make note of settings before beginning reset procedure. After PCM reset, the radio will not function until code is entered.
To clear codes or to reset Powertrain Control Module (PCM), use PDU scan tool or generic scan tool following manufacturer's instructions. Codes can also be cleared by turning ignition off and disconnecting negative battery terminal for 30 seconds. Disconnect scan tool from DLC, or reconnect negative battery terminal.
