Hello together, my Volvo 850 Kombi is shut down and now the HU and ASU should be renewed. Unfortunately, the ABS & TRACS luminaire lights up permanently. Unfortunately, my last screwdriver workshop in Berlin is no longer available, but already at the last TÜV preparation there was this problem. If I remember correctly, the diagnosis computer reported a failure at the back right side of the sensor. In the available diagnostic computer at that time, my vehicle could not be found and the readout Somehow you are bypassing it and the HU has been issued without any problems. An interesting detail is that the 850’s is one of the last built and the diagnostic plug is already in the center console in the interior under the coin holder. Now the question is how to either fix the error or disable the control lights to complete the HU successfully. What would you advise me to do pragmatically? Best regards!
