What is the reason for BMW DME interface failure?
1 Answers
There are many reasons for BMW DME interface failure, and it is necessary to go to a 4S shop to troubleshoot one by one. The following specifically introduces the troubleshooting methods: Read the fault content: After receiving the vehicle, press the start button of the vehicle, and the engine can start. The engine idles roughly, the engine fault light on the instrument panel lights up with an alarm, and the central information display shows "engine power reduced". Connect ISID for diagnostic testing and read the fault content of the engine control system. Perform troubleshooting: Check whether the wires and plugs between the DME box and the injection device are properly connected. Check whether the control module can communicate.
