Question
Hi Rob,
I am not sure if this is your area of expertise but I am hoping you might be able to help with advice. The car has covered only 18000 miles faultlessly since new but now the Brake and Traction Control lights show on my car. I have a Tech 2 which shows no communication with the chassis function although the engine etc data are available. When I scan via the on board scanner I get 'no ABS codes' readout. Everyone tells me the Electronic Brake and Traction Control Module has failed. Unfortunately these appear to be no longer available from the US or Bauer Millet. Can these units be repaired/reconditioned and if so do you know anyone who can do this sort of work please.
If you think it is not the EBTCM, any thoughts you might have would be useful.
Thanks in advance and best wishes.
John

Hello,

I do not know what your access is to used parts for thiis car in the UK, but I would try that option if possible.

If not, another option would be going on line and checking for a GM dealer who might stock the part. They have the capability of checking with the Cadillac dealers and possibly someone is sitting on the component in old stock.

If not, try on line for salvage yards. I would bet with any of these options you will get the part you need.

Good luck!

Expertise

Alarm system questions cannot be answered on this forum. These systems are not what I can answer. Without being physically at the vehicle and not knowing what kind of electrical service has been done on the vehicle, there is no possible way to give an accurate answer over the internet. My expertise is in Ignition/key based anti-theft systems. These issues include GM VATS (resistor chip in key blade) PASSLOCK (MRD)-ignition lock rotation based, no special ignition key and the PKIII Transponder (computer chip in key) systems. These systems are not alarm based and are integral with the starting of the engine. This is why I cannot diagnose alarm problems without physically looking at the vehicle: Alarm systems are a completely different annimal than ignition key/lock based anti-theft system. Many alarm questions come from vehicles 10 years old, and since older, many hands that had been involved over the years.I am an expert in all GM factory (ignition/key based)systems. Alarm system questions pose to many situations beyond my knowledge as to what has been done to the vehicle over the years. Some guy may have actually wired the stereo into the alarm system. Who knows? Over my past 30 years in vehicle wiring repair, I have seen unbelievable wiring disaters done by guys that consider themselves "mechanics." I have seen stereos and alarms intalled using surgical tape. I have seen modules burn up, un-fused circuits, wiring jambed between the doors and even lamp cord used for a starter kill. To answer alarm questions over the internet without examining the vehicle is like asking; What does it take to remove a dent?
