76-5-4 DESCRIPTION AND OPERATION
Description - electric seats
General
All markets use the same electric seat system. Electically operated lumbar support is optional. The system consists
of an electrical sub-system and a mechanical sub-system.
The electrical sub-system consists of the following components:
lBCU.
lSeat power relays.
lSeat switch packs.
lSeat fore/ aft motors.
lSeat cushion front up/ down motors.
lSeat cushion rear up/ down motors.
lSeat squab motor.
lLumbar pump.
lLumbar deflate solenoid.
The mechanical sub-system consist of the following components:
lGear wheels.
lRack and pinion assemblies.
Seat power relay
Located beneath the seat, the seat power relay supplies battery voltage to the satellite fuse box. Operation of the
relays is controlled by the BCU.
Voltage to the seat power relays is from fuse 5 in the engine compartment fuse box. The BCU controls the earth for
the relay coils. Operating the seat power relays provides voltage to the satellite fuse box under each seat.
Satellite fuse box
Located beneath the seat, the satellite fuse box provides circuit protection for the wiring to the seat switches and
motors. It also protects the lumbar inflate and deflate circuits.
The seat power relay provides voltage directly to the 40A fuse in the satellite fuse box. Voltage from this fuse feeds
the seat switch pack. The 3A fuses in the satellite fuse box protect the wiring to the lumbar pump and lumbar deflate
solenoid. Voltage to the 3A fuses comes from the seat switch pack.

SEATS
DESCRIPTION AND OPERATION 76-5-5
Seat switch pack
Each seat switch pack contains two switches representing the seat cushion and the seat squab. The switches provide
the following adjustments:
lSeat fore/ aft.
lCushion front up/ down.
lCushion rear up/ down.
lSquab fore/ aft.
lLumbar inflate.
lLumbar deflate.
The voltage supply to the seat switch pack is from the 40A fuse in the satellite fuse box. A pair of switches controls
the operation of each seat motor, the lumbar pump and the lumbar deflate relay.
Seat fore/ aft motor
The seat fore/ aft motor is a permanent magnet motor coupled to a rack and pinion assembly. Should the motor seize
or stick for 6 seconds or more, an internal thermal cut out switch will trip to remove voltage from the motor. Reset
time for the switch is 35 seconds.
