What is the reason for the fault code U007300 in the Baojun 730?
1 Answers
TCM power or ground is suddenly interrupted during driving, causing the entire TCM control module to stop working. Vehicle fault self-inspection terminal: The vehicle fault self-inspection terminal can diagnose the status of sensors and actuators in the electronic control system and whether the ECU is functioning normally. If abnormal, it will transmit a fault code. When a circuit in the electronic control system generates a signal that exceeds the specified range, the fault information related to that circuit and its sensors will be stored as a fault code in the ECU's internal memory. Maintenance personnel can use the diagnostic tool to read the fault code and display it. Reasons for the fault: TCM power or ground is suddenly interrupted during driving, causing the entire TCM control module to stop working. The CAN communication enable line of the TCM control module may suddenly disconnect or experience low voltage during driving, leading to CANBUS communication interruption in the TCM control module, or there may be an internal fault in the TCM control module.
