Mercedes-Benz S320L engine can't start. Various fault lights are lit for reference:
Maintenance and diagnosis process: 1, fault phenomenon confirmation: check the vehicle and find that the engine can't start, the gear can't shift gears, the instrument alarms for many times, and other functions are normal.
2. Read the fault code: use Mercedes-Benz Mercedes-Benz Star C4 original factory detector to quickly detect, and find that 6 modules CAN't be detected, and most of them report the fault of CAN system, but they can't identify which module has a problem, which leads to the paralysis of CAN system. When performing the function of clearing the fault code and reading it again, a fault message appears-"The diagnostic instrument cannot determine the actual position of the ignition switch, so it cannot perform the function of clearing the fault".
3. Detection of CAN waveform: Connect the special oscilloscope of Mercedes-Benz and observe the waveform of CAN line.
4. Waveform analysis.
5, check to determine the fault range.
