ABS, Break and Traction Control lights?
I have been having this problem for a while and cannot for the life of me figure it out. I have all three lights on when I drive but when I start the car sometimes they turn off then back on when I get a block down the street. I was thinking it might be the PCM because I have a non stock one in. Other idea was the ballasts for the HID lights could be making it happen. I was also thinking about taking out the PCM and checking the connections and cleaning them since I already checked all the fuses. Any ideas?

Step 1: Check your brake fluid (low fluid can and will cause the BRAKE light)
Step 2: Get your car scanned at a GM Dealership (Autozone can't read ABS codes)
Step 3: Find out which Wheel Hub Assembly went bad on you and replace it. (see Step 5)
Step 4: (if step 3 was a no go) check all the wiring to your wheel hubs and make sure nothing has come loose.

Hey quick while I just thought of it. If you do a wheel hub do you have to get an alignment if you do both or one? Funny think is I just had my tires rotated and they said my right front wheel hub was going out so I bet you are right but they wanted $500+ to fix it. I am pretty sure I can do it myself if I can do my breaks myself.

You shouldn't have to balance or align since that all has to deal with the way the rim rotates and it's weight distribution and such, but this doesn't effect the wheel at all.
If you take your rotors off, and see that assembly, that's the part you are replacing.
But yeah, the cost of the part + labor at a dealership is killer!!!

At the dealership they charge for everything so they will for sure charge for the scan. I think most places will since they have to pay for the tool to scan the codes other than regular "Engine light" codes.
PS- Thanks again man

Charging for the scan is part of the "diagnostics" cost. My dealership / mechanic charges $30 for diagnostic checks, so that's how much it was to scan my ABS codes.
