C121C DTC After Cam Swap
Anyone dealt with a DTC C121C torque request denied ??
I did a mild Comp Cams Stage 1 cam (201-300-17) with lockout on a 2010 Dodge Ram 5.7 2WD.
MDS delete- non MDS lifters and solenoid plugs - runs pretty good until my Traction Control light comes on.
The truck came in my shop with a blown motor so I dont know if it was an existing issue or not.
Book says causes are
EXCESSIVE LOAD ON ENGINE
TRACTION CONTROL OPERATING FOR TOO LONG
ANTI-LOCK BRAKE MODULE
POWERTRAIN CONTROL MODULE
I did an 2009 RAM 5.7 not tool long ago and did not have this problem, only difference it was a 4 WD
I swapped ABS module - no change.
