Listing your codes would help with the diagnosis.

This thread will be moved to the Tech section by Jack.

You say check engine light and also Traction. There are 2 different computers.

If you need a new EBTCM (Electronic Braking & Traction Control Module) they are only available used and cost between $1200 to $2400, and that's if you're lucky enough to find the same exact one you have. There are several ones made for a '99 depending on options.

But first, as mentioned already you should post the codes you have both active and history.

I, thankfully, do not have the problem with my car..... yet? Hopefully ever.

I haven't looked into it yet before. Which options affect which unit I would need?

On the top of the ebcm you'll find a sticker with a large letter such as V, M, or NK. You need to match the letter to the one you have on your car.


Example of the pump/EBCM bolted together. You can see the letter easily looking at the unit in your car. The pump rarely goes bad. The only part you need to replace is the half that has the letter.





Example of the EBCM itself. Different code

Why would you clear the codes? What codes are showing up? Need more information before we can give you any useful advice.

There are 20+ DTCs that the EBTCM can have. Some are easy to fix, some are not. PLEASE post ALL the DTCs in all the modules.

That will give us the proper info so that we can help you.
