PINPOINT TEST D: THE ONE-TOUCH DOWN (OTD) FEATURE IS INOPERATIVE

D1:

Normal Operation
Under normal operation, voltage is provided to the one-touch down (OTD) relay switch and coil from the accessory delay relay. Ground for the OTD relay coil is supplied by the smart junction box (SJB) when an OTD command is sensed from the driver window control switch through circuits 991 (TN/LB) and 992 (WH/BK).

Possible Causes
- An open in circuit 992 (WH/BK)
- Smart junction box (SJB)
- OTD relay
