The control module turns OFF the malfunction indicator lamp (MIL) after 3 consecutive ignition cycles that the diagnostic system runs and does not fail
- A current diagnostic trouble code (DTC) clears when the diagnostic cycle runs and passes.
- There may still be a history of DTC-s stored in the system. These will clear after 40 consecutive warm-up cycles, if no failures are reported by any other related diagnostic system
- Manual resetting of the MIL and any DTC stored in the system, requires the use of an OBD 2 scan tool connected to the data link connector for communication with the vehicle. Follow the instructions of the scan tool for both retrieval and resetting of DTC-s.
