Toyota Power Seats
Camry, Celica, Land Cruiser, Supra
DESCRIPTION & OPERATION
CAMRY
Driver's seat cushion moves 6 ways (front up and down, rear
up and down and slide forward and backward). See Fig. 1. Seat back
reclines forward and backward. Switch controls power and ground
circuits of power seat motors. Circuit breaker in power seat motor
protects circuit.
CELICA
Driver's seat is equipped with an adjustable lumbar (lower
back) support and side supports. See Fig. 2. System receives power
through power main relay (near battery, in relay block No. 2). Switch
controls power and ground circuits of power seat motors. Circuit
breaker in power seat motor protects circuit.
LAND CRUISER
Both front seats move 6 ways (front up and down, rear up and
down and slide forward and backward) and seat backs recline forward
and backward. Driver's seat is also equipped with an adjustable lumbar
(lower back) support. See Fig. 3. Switch controls power and ground
circuits of power seat motors. Circuit breaker in power seat motor
protects circuit.
SUPRA
Driver's seat slides forward and backward and reclines
forward and backward. Switch controls power and ground circuits of
power seat motors. See Fig. 4. Circuit breaker in power seat motor
protects circuit.

TESTING
POWER MAIN RELAY TEST
Celica
Remove power main relay (near battery, in relay block No. 2).
Check continuity between terminals No. 3 and 5. See Fig. 5. If there
is continuity, replace relay. If there is no continuity, apply battery
voltage across terminals No. 1 and 2. Check continuity between
terminals No. 3 and 5. If there is no continuity, replace relay. If
there is continuity, relay is okay.

POWER SEAT MOTOR TEST
1) Disconnect power seat motor connector. Apply battery
voltage across power seat motor connector terminals. Reverse polarity
to move seat in opposite direction. If power seat motor does not
operate, replace power seat motor.
2) If power seat motor operates, move seat fully in one
direction until it stops. With seat stopped, keep battery voltage
applied to terminals until circuit breaker is heard operating (4-60
seconds). If circuit breaker does not operate within 60 seconds,
replace power seat motor.
3) If circuit breaker operates within 60 seconds, reverse
polarity and wait until seat moves in opposite direction. If seat
moves in opposite direction within 60 seconds, power seat motor is
okay. If seat does not move in opposite direction within 60 seconds,
replace power seat motor.
POWER SEAT SWITCH TEST
Disconnect power seat switch connector. Check continuity
between specified terminals of power seat switch connector. See
appropriate POWER SEAT SWITCH CONTINUITY TEST table. Replace switch if
continuity is not as specified. See Figs. 6-8.
