Year = 1995 grand prix
Mileage = 195000
Engine size = 3.1 L
dash lights = ABS
codes = none
work done prior = replaced pads rotors
work done to repair = recent master cylinder
tech = JK
question = this is an intermittent trouble after driving for a while
the abs light comes on there are no codes stored in the computer. this
has been an ongoing trouble that began long before this last brake
service.
i have connected the autoxray 5000 scanner to the computer port and had
the car driven when the abs light comes on no fault codes are
displayed. we have replaced the master cylinder and completely bled the
entire
brake system starting at the distribution abs modulator block all the
way to the calipers. the brakes work fine but the abs light still comes
on after driving the amount of driving varies we are leaning heavily to
an electrical and or electronic failure of the abs control module but
would like some assistance to narrow the trouble down
JK:
I am not familiar with this model scanner, but i assume it is capable of
reading codes. An ABS light on with not codes is usually an EBCM problem.
Anytime there is a warning light, there SHOULD be codes. I have not had
many ABS light without codes. Motor packs are common, speed sensors,
harnesses, but ALWAYS codes.
I would suggest checking with a different scanner to be sure.
