ECU Type - ATE Teves
ECU location: Fitted to the back of the ABS pump (held on with four torx screws that are easily removed with a 4mm socket).
This is a very common failure on all Volvo ABS pumps built after 1995, causing the ABS light to come on along with the tracs light if fitted. When the fault codes are read there will usually be a fault code blaming the high pressure pump and/ora fault code blaming one or more wheel speed sensors. The fault is normally always the ABS module when these faults occur.
It is worth noting that the ABS module can be removed and the pump left in place thus alowing the vehicle to be driven with normal braking (no ABS).
