DIAGNOSTIC PROCEDURE

STEP 1. M.U.T.-III CAN bus diagnostics

Use M.U.T.-III to perform the CAN bus diagnosis.

Q. Is the check result normal?

	Go to Step 2.

	Repair the CAN bus lines (Refer to GROUP 54C - Troubleshooting, Diagnosis Code Chart ).

STEP 2. M.U.T.-III diagnosis code

Check if the engine-related diagnosis code is set.

Q. Is diagnosis code set?

	Diagnose the engine control system.

	Go to Step 3.

STEP 3. Symptom recheck after erasing diagnosis code

Q. Is the check result normal?
