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.
