Seating - 2nd Row - Power Release

Seating - Power Release

Overview

Pressing and releasing the LH (Left Hand) or RH (Right Hand) rear seat control switch (located at the back of the rear door opening) causes the corresponding rear seat backrest to fold and tumble forward for access to the third row seating.

System Operation

Seating - Power Release

Each second row power fold seat motor receives battery voltage at all times. The power fold seat motors contain internal switching that operate the motor until it moves to the reset position and turns off. The battery saver relay voltage output circuit from the BCM (Body Control Module) provides the control signal voltage to each seat control switch. For additional information about the battery saver feature, REFER to Battery Saver Interior Lighting. The seat control switches are momentary contact switches. When pressed and held for at least one second, switched voltage is applied to the power fold seat motor control circuits to initiate a pull and release cycle.
When the seat control switch is activated, the second row power fold seat motor retracts a cable (connected to the same seat latch mechanism as the manual release pull strap) to release the backrest recliner latches and allows the backrest assist spring to fold the backrest forward onto the seat cushion. The power fold seat motor continues to retract to release the seat-to-floor latches and allows the assist spring and strut dampener to lift and tumble the seat forward to the E-Z entry position for third row seat access. Immediately after the seat is fully released, the power fold seat motor returns the release cable and latches to a relaxed state, ready for manual latching. To return to a seating position, the seat must be manually latched to the floor and the backrest must be manually latched upright.

Component Description

Power Release Seat Motor

The power fold seat motors contain internal switching that operate the motor until it moves to the reset position and turns off. The power fold seat motor inputs contain the following circuits:
- Battery voltage (high current circuit to operate the motor)
- Ground (circuit provides ground for motor operation as well as logic of the integral electronics within the motor)
- Seat control switch input (when the seat control switch is activated, ignition voltage is present on this circuit)
