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 (Y/V) and (L/GY).
Possible Causes
- An open in circuit (L/GY)
- Smart junction box (SJB)
- OTD relay

| 1 | CHECK CIRCUIT (L/GY) FOR AN OPEN
|
Yes | Carry out the one-touch relay component test. See table at the end of this pinpoint test. If the relay tests OK, install a new SJB. See SMART JUNCTION BOX (SJB) , . Test the system for normal operation. |
| No | Repair circuit (L/GY) for an open. Test the system for normal operation. | ||
