Test S: The Power Seats Are Inoperative - Third Row Power-Fold Seat

PINPOINT TEST S: THE POWER SEATS ARE INOPERATIVE - THIRD ROW POWER-FOLD SEAT

Normal Operation
The third row power-fold seat relay is supplied battery voltage on circuit SBB12 (GN/RD) (right) and SBB05 (GY/RD) (left) 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). The power-fold seat relays will be provided ground on the coil side from the SJB for 30 minutes when the transmission selector lever is in PARK, and the liftgate, or liftgate glass, is open. The ground will be disabled 30 minutes after turning the vehicle off. If the ground is disabled after 30 minutes, the ground can be enabled by opening any door, pressing the unlock key on the key fob, pressing any keyless keypad button or turning the ignition key.
