Clear faults

Clear engine fault codes after reviewing the fault information and correcting the underlying condition.

Expected result

DTK completes the Key-off and Key-on process and confirms whether the fault codes were cleared successfully.

Important notes / prerequisites

Review and document the fault information before clearing. Confirm that the engine is safe for the required Key-off and Key-on process.
