My light came on awhile back. I checked all fuses and replaced the relay. Didn't fix it. Check the Ohms on the ABS senors and all were in correct range. Brought it to GM for them to check it out. Codes thrown were
CO1216
C1295
they said it could be one of the three problem.
1. Bad relay
2.Brake switch
3.EBCM which is like $455.

already replaced the relay, if it was a bad brake switch would my brake lights still work?
is there any other options?

check the 3rd brake light bulbs

my brake lights are fine, i'm asking if the brake switch was bad, would they still work cuz they do and my ABS doesn't work. No point in replacing something that doesn't need to be replaced

idk if you have headers on the car but check the wires to the front sensors.......mine are realllyyyyy close to the headers and i burnt one up.....when that happens the light comes on........id check that out first may be and easy cheap fix....

do you have a stock spoiler or an SS spoiler with the LED brake light?

thats your problem i think. did the light come on when you put the ss spoiler in? i read some where that an extra relay has to be installed with the ss led lights.

i just fixed this problem with my 95 Z and my ss spoiler. bascially the led does not give resistance like the stock bulbs do so you have to wire in a resistor to fix it. there is a post with a wiring diagram on how to fix this. it is about a week old in the lt1 section. search for it and you should see the 2nd or 3rd post with the link. i think it is titled "just changed to ss spoiler now abs light is on"

i got it put on and that is what it was, thanks!

This is an old thread but I figured I'd utilize it.

How do I know what relay to use? Will any relay work?

You need to find out whether or not a normally open or closed relay is used. Shoebox may have diagrams to answer at least that question.

Neither am I. Any 12v auto relay will work. If that relay is not charged in that diagram it looks to be a normally open relay.
