Hello to all, although I have read a lot here I could not find an answer to my question. Therefore here my drawn questions with the request for your participation. After guidance (on the diagnostic box GND & TBS bridged) I determined the code 14 (ABS sensor hi/li). ABS sensor hi/li replaced. After an instruction (10x brake pedal operated) and deleted the error from the error memory. Sporadic error still present. All four sensors cleaned and resistance measured a Inconspicuous. Battery disconnected and all plugs incl. the v. control unit sprayed with contact spray. Sporadic error still exists. AC voltage of the ABS sensors rear wheels measured and determined that when the wheels rotate about the same, the AC voltage on the right is only half as large as on the left. However, code 14 (ABS sensor hi/li) was shown.Now my question: Is it o.K. that one sensor brings less AC voltage than the other sensor? /re with less AC voltage is defective even though code 14 ABS sensor hi/li is output?
