Shift Motor Short To Ground is the generic description for the P1737 OBD2 code. TCCU sets DTC P1737 if TCCU detects Shift Motor control circuit is open or short to ground.

The TCCU receives feedback from the shift motor through the position encoder. Four encoder switch signals offer information on the rotational direction and position of the shift motor. The TCCU supplies 5 volts to the MPS (Motor Position Sensor). The shift motor functions when the mode switch is changed, and the MPS contact point generates an ON/OFF signal. The TCCU checks the operation of the shift motor when it receives 5 volts.
