VERIFICATION OF REPAIR:
- Inspect the vehicle to make sure that all engine components are properly installed and connected. Reassemble and reconnect components as necessary.
- After repairs are complete, erase all DTCs with the scan tool.
- Refer to the table below to determine if a learn procedure should be performed for the component that was removed or replaced. Not all learn procedures are available for all vehicles. If a component listed in the table is replaced and the correlating learn procedure is present in the scan tool, navigate to "Miscellaneous Functions" and perform the learn procedure before verifying repair. Failure to do so may cause the same, or another DTC to set.
