6.32.4 Diagnostic Information and Steps

6.32.4.1 Diagnosis Description

Understanding and familiarizing oneself with the working principle of the white body device before diagnosing faults in the white

body device, and then starting system diagnosis, can help determine the correct fault diagnosis steps when a fault occurs, and

more importantly, it can help determine the situation described by the customer belongs to normal operation. Any fault diagnosis

of the white body device should start with routine inspection, guiding maintenance personnel to take the next logical step for fault

diagnosis. Understanding and correctly using the diagnostic process can shorten the diagnosis time and avoid misjudgment of

faulty parts.

6.32.4.2 Routine Inspection

• Check for aftermarket devices that may affect the operation of the body in white system, ensuring that these devices do not

affect the operation of the body in white system.

• Inspect system components that are easily accessible or visible to make sure they are not visibly damaged or have conditions

that could cause failure.

6.32.4.4 DTC Confirmation

1.Connect the diagnostic instrument to the diagnostic interface, read and record the DTC, and then clear the DTC.

2. Restart the vehicle.

3. Read the fault code of the control system again to confirm whether the system has a fault code output.

– Yes:Diagnose based on the output fault code.

– No:Perform intermittent fault checks, refer to Inspection Of Intermittent Fault
