It's a 94 3.4 L 207 and I just finished a 20k restore job on it. The car looks showroom new but it started doing something after I picked it up. The ABS light has stayed on since the car sat for three months. I've driven it for 3k miles with the ABS light on thinking it would eventually turn off. (maybe just because it sat for so long) Unfortunately it hasn't turned off and now I'm getting a flashing traction light along with a flashing brake light. I'm guessing a wire has come loose somewhere but I'm not sure. Any ideas as to what it might be??? Thanks for any and all input y'all!

 

Hard to tell without a ABS scanner, but check the ABS wires to the front wheel sensors and to the rear wheel sensor by the differential, check that the center brake light works, check that all tires are the same size.

 

You can check the ABS trouble codes by using my 94/95 free scan app for the 3.4L:
Scan9495-V6 OBD1 scan program for 3.4L F-car - Firebird Nation

Check fuses 1 and 5 in the underhood fuse box. If they are ok, try swapping the ABS enable relay (C) with the Air conditioning relay next to it (B). If the ABS lamp goes out, replace the relay.
If all the above is ok, remove the ABS enable relay (C) and measure the voltages at relay socket contacts for C1(30) and C2(85). Both should be 12v with ignition ON. If no 12v at C1, check fusible link B. If no 12v at C2, check both ends of fuse 5 for 12v.

 

After replacing both hubs and both front calipers and the master cylinder and the ABS relay....the ABS light went off and the brakes work great...........now the brake light won't go off. Any ideas???

 

One possibility: The ABS Inop lamp can turn off once the fault is corrected, but the code remains in memory until 100 drive cycles are done without a repeat of the failure. Some ABS DTC's will turn on the Brake lamp also. You can only clear the ABS DTC's by using a scan tool (like mine above) or by waiting for 100 cycles. Removing power from the ABS module(s) will not clear the codes.

 

for brake light you might have set off the warning when the brakes where bled after replacing calipers or mc. try pushing the brake peddle as hard as you can. should reset it if thats it.
