Using Scan Tool
Connect DRBIII® scan tool to Data Link Connector (DLC). DLC is located below driver's side of instrument panel. (Scheme 736) Turn ignition on with engine off. Using screen prompts on scan tool, erase DTC from Engine Control Module (ECM) or Powertrain Control Module (PCM). Certain DTCs may also store a companion DTC, meaning that if a certain DTC is stored in the ECM or PCM, the same DTC will be stored in the opposite control module. It may be necessary to clear DTC from both ECM and PCM.
