Good afternoon,

ESP BAS, brake, ABS and traction lights are on. I have taken the car to a local shop and I was told that the ABS module will have to be replaced and that the dealer will have to reprogram it once installed. I would like to know if it is true that only the dealer can reprogram the module or would I be able to possibly find another mechanic that can handle the job without going to the dealer?

Hi,

I have to be honest. I just read through the manual for replacement. It doesn't indicate that reprogramming is even needed. It does say to actuate it to make sure it works, but that is all that is listed.

Here are the actual directions. The attached pic correlates with both the removal and installation. The only thing not listed that I would recommend is to disconnect the battery prior to working on this and don't reconnect it until the job is complete.
