ABS problem with my 2000 Pontiac GTP
3.8
question = Why does my ABS light go on. I have some codes I can not find
definitions for.
P1521 tcs issue
DTC C0244
DTC C0550
any help would be appreciated.
Thanks
JK:
C0244 has to do with traction control. Problem with a signal between the PCM and
ABS/Traction module.
C0550 is an internal malfunction in the ABS/traction control module.
The other is a fault in traction control torque request.
Sounds as if these things are related. Possible faulty ABS/traction module, PCM,
or connector problem at either of those. Let me know if you need more help.

WARNING LIGHTS
ABS / Anti lock brake warning.
The anti-lock braking system uses several sensors, motors, and a computer module in conjunction with the
normal braking system. The systems sensor tire / wheel lockup.
The ABS system regulates the brake pressure in order to reduce wheel lock-ups. Reduced wheel lock-ups
improve the driver's control of the vehicle during braking in wet or snowy conditions.
Improved stability and steering enable greater control of the vehicle in the case of an abrupt stop.
The ABS operation is available from 5 km/h (3 mph) to the maximum vehicle speed.
A warning light means a problem was detected, and the system needs to be scanned for codes in order find
out the area the fault is in. With the light on, ABS operation is not present, but normal braking is.

1998 Pontiac Grand Prix GT.
Engine size 3.8.
Warning lights: ABS
Repairs for this problem = I took it in and had it scanned and was told that i needed a new abs
module and was told it could take about 5-6 hours to do is this right and it is it a hard job or just long
i am thinking about doing it myself any tips on going about doing this
Question = is the replacement of the abs module a tuff job

Answer: The ABS unit itself consists of two major components. The
EBCM which is the 'computer' portion of the ABS system, and the BPMV
which includes the pump motor, solenoids, and brake fluid controls. I'm
assuming you must need either the latter, or both of these due to the
time they told you it would take to fix. If it was just the EBCM, that is the
least difficult part to replace and would probably take only an hour or
more. Sometimes the bolts holding the two together are rusted which is a
time consuming thing also. If you need the BPMV, that repair is a bit more
difficult, and requires the brake lines removed from the system, and then
the entire brake system bled afterwards. There is also a scanner needed
to control the bleed function of the ABS, and what's called 'rehoming' the
motors. You'll most likely need a professional to do this job.
