Default ABS Module Replacement

I bought a salvage unit from a junkyard and was told it was a working unit. I had my mechanic install it yesterday. When I brought him the car the only advises on the car was ABS and TRAC Control. He installed the used module from the junkyard and those two lights are still on plus the Red BRAKE, and amber Check Engine lights. The speedometer and odometer do not work. And it says "Wrong Part Installed"

Help....what is going on other than the obvious wrong part installed.

I am thinking I need to send my original module to be rebuilt.

Looking forward to some insight from members of this forum.

The ABS module and the ECU are communicating with one another over the CAN bus technology. Jaguar wanted to make sure that the ECU is talking to a legitimate Jaguar ABS module, so it came up with the concept of VCATS. Basically, once you are pretty sure the ABS module you installed is correct (correct full part#), you have to use the SDD/IDS factory software to have the ECU "recognize" the ABS module. This is known as "programming" the module. More likely than not, a visit to the dealer is required. If your independent mechanic has an advanced scan tool, maybe he can do it too, but it is unlikely. "Wrong part fitted" is what the ECU says when the VCATS does not match. Unfortunately, junk yards typically do not list this number. There is a sticker in the trunk wheel well that lists all the accepted VCATS.

This state of affair is why most folks try and repair whatever module they already have (no programming necessary). The tpical failure point is the failed solder joints for the power pins on the control board. This has been documented many times over on this forum, and can be fixed with somewhat basic soldering skills once the protective case has been breached.

Best of luck, keep us posted.

That is the plan now...to submit the first module to a repair facility and put it back on my car.
