4x4 DSC light ON, no others; 5F0C DSC sensor, internal – SOLVED

[Junkycosmos]

I unplugged the battery cable overnight last night: just to be sure. Indeed no change; light still on. Then did SAS reset turning wheel lock to lock which did clear the Steering Angle Sensor code but the DSC internal error is still present.
>DSC - 5F0C DSC : DSC sensor, internal –Fault currently present


Driving I can confirm that ABS is fully functional and working well on the ice.

In GT1
I can also fully control the ABS pumping of the lines (brake line mix up check)
I can see Steering Angle Sensor reporting value and pressure via brake pedal.
HOWEVER
I cannot see any values reported for Rotation rate or Transversal acceleration; they both always reads ZERO, even during brief drive test.

Question1: can anyone confirm IF laptop version of GT1 reports values here and under what conditions?


Quesiton2: what errors in GT1 are seen when the transfer case activator plastic gear turns to dust?


thanks again for the help

My opinion is that since you have the same error as mine, and no ABS light (which IIRC should also be on if its the DSC/ABS module) then its one of the sensors other than the wheel speed sensors (obviously since you don't get the ABS light).

Since I no longer have the X or the GT1 I'm limited in what I could contribute further.

I forgot how many other sensors there are. Maybe its only the yaw sensor that's left. In which case, there's your answer.

Did you happen to have a CANbus error too? When you went through the test plan, did you get the same screen results in the GT1 as mine?



Regardless, my bet is that same yaw sensor.

In this case, only 2 sensor left to be the problem, one is the yaw sesnor and the other one is the DSC module itself. My guess is the yar sensor.
