Seat Driver Front Up Down Motor Stalled
Description
During self-test, the DSM attempts to operate the appropriate seat track motor and uses the motors position sensor to monitor movement. If no motor movement is sensed, the DTC is set. The DSM retries motor operation on the next activation of the seat control switch. If no movement is detected after 250 milliseconds, the DSM disables the output.
