Power Seats - Operation
OPERATION
The power seat system receives battery current through a fuse in the Totally Integrated Power Module (TIPM) and remains operational, regardless of ignition position.
When a power seat switch is actuated, a battery feed and a ground path are applied through the power seat switch contacts to the appropriate motor or motors. The motor and drive unit operate to move the seat in the selected direction until the switch is released, or until the travel limit of the gearbox and linkage is reached. When the switch is moved in the opposite direction, the battery feed and ground path to the motor is reversed through the switch contacts. This causes the motor to run in the opposite direction.
The power seat motors, gearboxes and linkage cannot be adjusted or repaired and if inoperative or damaged, the entire power seat adjuster and seat cushion pan, or the power reclining seat back must be replaced as an assembly Service and Repair or Front Seat Back Recliner - Removal.
