ABS/ESP CONTROL MODULE ERROR U0121
Hello, some months ago the car started to have problems with the ABS control module, the dispaly was showing multiple errors,
the diagnostic tool returned the error 5001 internal ABS module Fault,
i did sent the complete assembly to a repair shop, ACTRONICS here in europe, they send me back the Assembly after changing the CPU, i did install it
and i got the Error U0121 can bus error it is a lack of comunication with the ABs control unit,
i did resent the control unit they did change again the CPU and send me back the module, and still this errore
before to spend many money at the dealer i would like to know if somebody did have the same problem and if is it available
the electrical diagram of the modle to see which pin to check for the canbus
