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.
The Traction Control System is controlled by the ABS system.
