Is it normal for several warning lights to appear after a new car loses power?
1 Answers
This phenomenon is the car alerting the owner to corresponding faults, which is not a normal condition. Reasons for faults appearing after power loss: When the car loses power, the corresponding computer modules will record this situation as fault codes and store them. Therefore, when power is restored, corresponding warning lights will illuminate. Checking the reason for warning light illumination: The engine control unit includes a built-in self-diagnostic system that can detect faults in the engine electronic control system. When a fault is detected, the engine control unit stores the fault as a code in memory and illuminates the engine fault warning light (check warning light) on the instrument cluster.
