500E cranks but will not start
This is a '92 500E and I was working with the diagnostics and I arc'd from Pin 3 of the X11/4 to the CAN. The ignition was off. Now when I turn the key all the lights on a dash light except for the CE light. The engine cranks but will not fire.
I am getting Error codes that state no communication with the LH module.
Code 20 on PIN 4, Code 7 on Pin 7, Code 9 on Pin 8 and nothing on Pin 19. All these point to an open circuit. I've checked all the fuses I could locate. I'm hoping that there is one fuse I missed or something else before I consider bring the LH module in for service or replacement.
Any ideas?
