ABS Not Working after Installing new gears.
Preparing my 1994 Caprice wagon for towing.
Just had 3.08's Installed which originally had 2.56's.
The 3.08's were from my 95 Impala SS.
After installation Re-flashed the PCM for the 3.08's gears.
Now the ABS INOP light is coming on.
Tested the Front Wheel Sensors and Pinion Sensor on the Pinion housing.
They were all working properly. The Car has new 94 ABS Brain.
When starting up the engine ABS light reads the Brain and goes off.
Travel about 30 seconds the ABS INOP Light comes on.
Attached new SnapOn Test tool to check everything out.
Results:
The Speedometer is reading the same speed as the Front Wheels
The Rear Sensor was reading about 5 mph less.
Have TunerCat. How can this be corrected?
