Normal Operation
The left third row power-fold seat relay coil side is supplied battery voltage on circuit SBB05 (GY/RD) and is hot at all times. The ground is supplied to each third row power-fold seat relay on the coil side through circuit CPS48 (BU) and controlled by the smart junction box (SJB). When the left third row power-fold seat switch is pressed, voltage is supplied through the switch side of the left third row power-fold seat relay on circuit SBB05 (GY/RD) and supplied ground on circuit GD149 (BK/GY). When pressing the left third row power-fold seat switch in the opposite direction, the left third row power-fold seat switch reverses the polarity to the left third row power-fold seat motor, which moves the third row seat backrest in the opposite direction.
Possible Causes
An inoperative third row power-fold seat can be caused by:
- fuse(s).
- wiring, terminals or connectors.
- a faulty left third row power-fold seat switch.
- a faulty left third row power-fold seat relay.
- a faulty left third row power-fold seat motor.
