Power Seat System

The power seat system option allows the driver and front seat passenger to electrically adjust their seating positions for optimum control and comfort. The driver side power front seat can be adjusted in eight different directions: up, down, front up, front down, rear up, rear down, forward, rearward and recliner forward and rearward. The passenger side power front seat can be adjusted in four different directions: forward, rearward and recliner forward and rearward.

The power seat system receives battery current through a 40 amp fuse in the Integrated Power Module (IPM) and a 30 amp circuit breaker under the seat so that the power seats remain operational, regardless of the ignition switch position.

Identifying A Side Airbag Equipped Seat:

WARNING: SOME VEHICLES ARE EQUIPPED WITH SEATBACK MOUNTED AIRBAGS. BEFORE ATTEMPTING TO DIAGNOSE OR SERVICE ANY SEAT OR POWER SEAT SYSTEM COMPONENT YOU MUST FIRST DISCONNECT AND ISOLATE THE BATTERY NEGATIVE CABLE. THEN WAIT TWO MINUTES FOR THE SYSTEM CAPACITOR TO DISCHARGE BEFORE FURTHER SYSTEM SERVICE. THIS IS THE ONLY SURE WAY TO DISABLE THE AIRBAG SYSTEM. FAILURE TO DO SO COULD RESULT IN ACCIDENTAL AIRBAG DEPLOYMENT AND POSSIBLE PERSONAL INJURY.

The eight-way driver side power seat is also available with the heated seat and/or memory seat system. The memory seat system automatically positions the power seat for two different drivers.

The power seat system includes the following components:
- Power seat recliners
- Power seat switches
- Power seat tracks
- Circuit breaker

The power seat system with memory and heated seat options includes the following components:
- Power seat recliner
- Power seat switch
- Power seat track.
- Memory Seat Mirror Module (MSMM)
- Memory set switch
- Heated Seat Module (HSM)
- Heated seat switch
- Electronic Vehicle Information Center (EVIC)

The power seat system receives battery current through fuse #22 in the Integrated Power Module (IPM) and a circuit breaker under the front seats, regardless of the ignition switch position.

When a power seat switch control knob or knobs are actuated, a battery feed and a ground path are applied through the switch contacts to the appropriate power seat track adjuster motor. The selected adjuster motor operates to move the seat track through its drive unit in the selected direction until the switch is released, or until the travel limit of the seat track 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.

No power seat switch should be held applied in any direction after the seat track has reached its travel limit. The power seat adjuster motor each contain a self-resetting circuit breaker to protect them from overload. However, consecutive or frequent resetting of the circuit breaker must not be allowed to continue, or the motor may be damaged.
