Conditions for Setting the DTC
WARNING: This page is about a different car, the 2002 Oldsmobile Aurora and 2001 Oldsmobile Aurora. However, it is still accessible from the selected car via links, so may be relevant.
If the input received by the MSM from a motor being driven in a commanded direction changes by more than 10 counts or 0.1 volts in the wrong direction, the MSM will set this DTC.
