If circuit is as specified, inspect the door lock signal.
If the circuit is not as specified, inspect the circuits connected
to other parts.
11. INSPECT DOOR LOCK SIGNAL
HINT:
When the relay circuit is as specified, inspect the door lock sig-
nal.
(a) Connect the connector to the relay.
(b) Connect the positive (+) lead from the voltmeter to termi-
nal 3 and the negative ( −) lead to terminal 4.
(c) Set the door lock manual switch to UNLOCK, and check
that the voltage rises from 0 V to battery positive voltage
for approximately 0.2 seconds.
(d) Reverse the polarity of the voltmeter leads.
(e) Set the door lock manual switch to LOCK, and check that the voltage rises from 0 V to battery positive voltage for
approximately 0.2 seconds.
If operation is not as specified, replace the relay.

after ignition switch ON → OFF (ACC).
If circuit is as specified, replace the relay.
If circuit is not as specified, inspect the circuits connected to oth-
er parts.

8. INSPECT REAR VERTICAL MOTOR CIRCUIT BREAK-
ER OPERATION
(a) Connect the positive (+) lead and the negative ( −) lead
from the battery to the rear vertical motor connector (illus-
trated terminals), and move the front edge of seat cushion
to the highest position.
(b) Continue to apply voltage, and check that there is a circuit
breaker operation noise within 4 to 60 seconds.
(c) Reverse the polarity, check that the seat cushion begins to descend within approximately 60 seconds.
If operation is not as specified, replace the motor.
9. INSPECT RECLINING MOTOR (DRIVER’S SIDE) OP- ERATION
(a) Connect the positive (+) lead from the battery to terminal 1 and the negative ( −) lead to terminal 2, and check that
the motor turns clockwise.
(b) Reverse the polarity, and check that the motor turns coun-
terclockwise.
If operation is not as specified, replace the motor.
10. INSPECT RECLINING MOTOR (DRIVER’S SIDE) CIR- CUIT BREAKER OPERATION
(a) Connect the positive (+) lead from terminal 1 and negative
(−) lead to terminal 2.
Check that the seat back reclines to the most forward
position.
(b) Continue to apply voltage, and check that there is a circuit breaker operation noise within 4 to 40 seconds.
(c) Reverse the polarity, and check that the seat back starts
to fall backwards within approximately 60 seconds.
If operation is not as specified, replace the motor.

SRS AIRBAG
PRECAUTION
The LAND CRUISER is equipped with an SRS (Supplemental Restraint System) such as the driver airbag
and front passenger airbag. Failure to carry out service operation in th\
e correct sequence could cause the
SRS to unexpectedly deploy during servicing, possibly leading to a serious accident. Before servicing (in\
-
cluding removal or installation of parts, inspection or replacement), be sure t\
o read the precautionary notices
in the RS section.
