Hi. I have a weird fault code in my rear sam ,9230 (The input for the annalog crash signal has short circuit to positive),
My car is a CL500 2007 (W216) and the fault only showed up after I left the car in for ceramic coating (May have nothing to do with it).
All other modules show no problem including the Air bag unit.
I have tried to find info on line but no luck.
The car is working fine in every way.
Any ideas would be great.
Kind Regards.
Pat.
