Warning: Reading fault codes when troubleshooting a vehicle is only a small step in the overall
diagnostic process. Vehicle fault codes are provided as a reference only and parts cannot be

and the service technician must strictly follow the operating instructions and procedures described
in the vehicle service manual to identify the root of the malfunction.
