Has anyone come across the ABS/ESP control unit faulty fault code?? It also comes up with variant encoding wrong. The KTS has pulled this info off for me but I cant seem to go any deeper into confirming the unit is faulty as there just isnt the information out there. The customer complained of pulling up for fuel going in and paying and when restarting the light came on. It seems strange to me that the code will clear and all lights off when the ignition is on but when the engine is started and it recieves an engine speed signal the unit becomes faulty and the light comes straight on even without rotating a wheel? Having the new MT Pro delivered tomorrow so will see what I can pull with that.
