Clearing Diagnostic Trouble Codes

Disconnecting negative battery cable, Powertrain Control Module (PCM) connectors, PCM ground wire, or main fuse will clear DTCs. DTCs can also be cleared using a Tech 2 or other OBD-II compatible scan tool connected to 16-pin Data Link Connector (DLC). See Figure. DTCs will also clear when fault that originally set that DTC is not detected during 40 engine warm-up cycles. A warm-up cycle is when vehicle coolant temperature rises by 72°F (22°C) or reaches 158°F (70°C) after engine has first started. DLC is located below left side of instrument panel, accessible from driver's side. Follow scan tool manufacturer's instructions when clearing DTCs.
