Test U: The Power Seat Is Inoperative/Does Not Operate Correctly - Third Row Power-Fold Seat, Right
PINPOINT TEST U: THE POWER SEAT IS INOPERATIVE/DOES NOT OPERATE CORRECTLY - THIRD ROW POWER-FOLD SEAT, RIGHTNormal Operation
The right third row power-fold seat relay coil side is supplied battery voltage on circuit SBB12 (GN/RD) and is hot at all times. The ground is supplied to the right third row power-fold seat relay on the coil side through circuit CPS48 (BU) and controlled by the smart junction box (SJB). When the right 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 SBB12 (GN/RD) and supplied ground on circuit GD149 (BK/GY). When pressing the right third row power-fold seat switch in the opposite direction, the right third row folding seat switch reverses the polarity to the right third row folding seat motor, which moves the third row seat backrest in the opposite direction.
This pinpoint test is intended to diagnose the following:
- Fuse(s)
- Wiring, terminals or connectors
- Right third row folding seat switch
- Right third row folding seat relay
- Right third row folding seat motor
- SJB
