DIAGNOSIS

Power Driver Seat

Caution : If the driver seat motor is powered directly from a battery, personal injury could be caused by sparking and sudden heating of the terminals if the wires from the battery are touched together. Use a fused jumper wire, and use terminal test adapters if available. If terminal test adapters are not available, use insulating tape to reduce the possibility of touching the jumpers together.

Diagnostic Aids

If resistance is measured between the terminals of the motor connectors, the frontward/backward motor resistance is approximately equal to 1 Ω, the front height motor resistance is approximately equal to 5 Ω, and the rear height motor resistance is approximately equal to 9 Ω.

  3. Connect a jumper wire between the test battery negative terminal and the DK BLU wire at terminal 3 on the motor side of the power driver seat switch.
  4. Carefully connect a fused jumper wire between the test battery positive terminal the DK BLU/WHT wire at terminal 4 on the motor side of the power driver seat switch. The two terminals are close together, and the motor may have a short circuit, so a fused jumper wire is recommended. Do not allow the wires from the battery to touch each other. If the motor is okay and it is not at the end of its travel, the power driver seat should move.
  5. To enable the motor to operate in the opposite direction, carefully reverse the battery connections between DK BLU and DK BLU/WHT.

GENERAL DESCRIPTION AND SYSTEM OPERATION

Seats

Do not attempt to change the designed seat position by altering the designed seat adjuster-to-floor pan anchor provisions or the seat adjuster-to-seat frame anchor provisions. Changing the seat position could affect the performance of the seat system.
This vehicle is equipped with front bucket seats with separate, adjustable head restraints, and a three-passenger rear bench seat with an optional split folding rear seat. The front bucket seats also have a recline, a height, and a lumbar adjustment. A power driver seat is optional. Seat cushions and seatbacks have formed foam pads, which fit the contours of the full panel seatback frame assembly and the designed contour of the seat cushion frame.
