The Electronic Shift Module (ESM) monitors the internal Auto Shift Manual Mode circuit for electrical failures. The Auto Shift Manual Mode switch is compared to the actual shifter position. If a discrepancy is detected, the switch is considered stuck open or closed depending on the actual shifter position. If a fault is detected with the internal manual mode switch, a DTC will set.
