mini cooper engine light on speedometer
1. This situation may be caused by the motor failure of the vehicle. After the vehicle is started, the generator will send electricity to the battery to maintain the normal use of various circuits of the vehicle. If the voltage delivered by the generator is unstable, the battery will be insufficient, and the instrument panel of the car will light up for a while and the screen will be black.
2. Poor contact of the connecting wire of the vehicle's instrument panel or water ingress into the line will cause damage to the instrument panel, and the vehicle's instrument panel will light up for a while and then black. If the owner encounters the above conditions when using the car, he/she needs to go to the 4S shop or auto repair shop in time and have the vehicle serviced by professional auto circuit personnel, so as not to affect the normal use of other circuits of the car and the driving safety of the owner.Connect the diagnostic instrument for detection, and store the fault code "420106 - shift self-locking solenoid: the shift lever is faulty and not locked at P" in the transmission control system. Check the function of the shift lever. The shift lever can be locked in the P position. When the brake pedal is pressed, the P lock can be released. The gear shift and the gear display on the instrument panel are also normal. Press the brake pedal repeatedly, and you can hear the working sound of the shift lever lock solenoid valve.
Attempt to clear the fault code, unable to achieve. Due to the lack of contact with this vehicle type, the fault code given by the diagnostic instrument is not fully understood. In order to find out the relationship between the fault code and the shift module, pull out the connector of the shift module and read the fault code again. At this time, the fault code "420102 - Shift lever locking solenoid valve short circuit to the positive pole or open circuit" appears. In this way, it can be determined that the 420106 fault code belongs to the internal fault of the shift module. Place the shift lever in the flashing position, and the fault code can be cleared. It is more certain that it is the internal fault of the shift module. Since the transmission control unit can report the fault code of locking in gear P, there must be a switch or sensor to monitor the locking position in gear P.
The reason why the mini engine fault light is on is: 1. The mixture combustion is poor; 2. Sensor failure; 3. Maintenance problems; 4. Oil quality problem. The solution to the mini engine fault light is to check the water temperature gauge and oil pressure alarm lamp. If the water temperature gauge and oil pressure alarm lamp do not alarm, control the vehicle speed and drive to the maintenance station for inspection in time; If the oil pressure alarm light is on, pull over and call the maintenance station for help. The length, width and height of mini are 3832mm, 1727mm and 1453mm respectively, the wheelbase is 2495mm, and the maximum speed is 193km/h.
