• Driver seat shown, passenger seat similar.
The driver and passenger power seat can be adjusted in eight different ways using the power seat switch. The power seat switch is located on the lower outboard side of the seat cushion on the seat cushion side shield (3) on all models. The eight way power seat system incorporates a switch with both the seat cushion control paddle (2) and seat back recliner paddle (1).
The individual switches in the power seat switch cannot be repaired. If one switch is damaged or inoperative, 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 via the controller area network bus circuit, when the driver memory seat switch control knob is actuated. The MSM is responsible for the 12 volt 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.
