4.6.4 Diagnostic Information and Steps
4.6.4.1 Diagnosis Description
Before diagnosing faults in multi in one power distribution equipment, Understanding and familiarizing oneself with the working
principle of multi in one power distribution equipment before starting system diagnosis can help determine the correct fault
diagnosis steps in the event of a fault, and more importantly, it can help determine whether the situation described by the
customer belongs to normal operation. Any fault diagnosis of multi in one power distribution equipment 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.
4.6.4.2 Routine Inspection
• Check the after-sales installation devices that may affect the operation of the multi in one power distribution system to ensure
that these devices do not affect the operation of the multi in one power distribution 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.
4.6.4.3 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
