Power Seat Switch: Description and Operation
SWITCH-SEAT
DESCRIPTION
The driver power seat can be adjusted in eight different ways using the power seat switch. The passenger power seat can be adjusted in four different
ways. The power seat switch is located on the lower outboard side of the seat cushion on the seat cushion side shield on all models.
The individual switches in the power seat switch assembly cannot be repaired. If one switch is damaged or faulty, the entire power seat switch must be
replaced.
OPERATION
When a power seat switch is actuated, a battery feed and a ground path are applied through the switch contacts to the power seat adjuster or recliner
adjuster motor. The selected adjuster motor operates to move the seat or recliner through its drive unit in the selected direction until the switch is
released, or until the travel limit of the adjuster is reached. When the switch is moved in the opposite direction, the battery feed and ground path to the
motor are reversed through the switch contacts. This causes the adjuster motor to run in the opposite direction.
On vehicles equipped with memory system, a resistance signal is sent to the Memory Seat Module (MSM) via the Controller Area Network (CAN) bus
circuit, when the driver memory seat switch control knob is actuated. The MSM is responsible for the 12v battery feed and ground path to the power seat
adjuster motor. The adjuster motor operates to move the power seat adjuster mechanism through its drive unit in the selected direction until the switch is
released, or until the travel limit of the adjuster is reached.
No power seat switch should be held applied in any direction after the adjuster has reached its travel limit. The power seat adjuster motors each contain a
self-resetting circuit breaker to protect them from overload. However, consecutive or frequent resetting of the circuit breaker may result in motor
damage.
