Repair Verification

WARNING: This page is about a different variant/trim than selected.
  1. Ignition OFF.
  2. Install any components that have been removed or replaced during diagnosis.
  3. Perform any adjustments, programming or setup procedures that are required when a component is removed or replaced.
    4. NOTE:

    If the DTCs are not cleared the ECM will disable boost control and limit the system to mechanical boost only, resulting in a substantial decrease in engine power.

  4. Clear the DTCs with a scan tool.
  5. Ignition OFF and all vehicle systems OFF. It may take up to 2 minutes for all vehicle systems to power down.
  6. If the repair was related to a DTC, duplicate the Conditions for Running the DTC and use the Freeze Frame/Failure Records, if applicable, in order to verify the DTC does not reset. If the DTC resets or another DTC is present, refer to the Diagnostic Trouble Code (DTC) List - Vehicle and perform the appropriate diagnostic procedure.
