INSTALLATION
NOTICE:
Never use SRS parts from another vehicle. When replacing parts, replace with \
new parts.
Never reuse the airbag sensor assembly involved in a collision when the airbag has deployed.
Never repair a sensor in order to reuse it.
1. INSTALL AIRBAG SENSOR ASSEMBLY
(a) Using a torx wrench, install the airbag sensor assembly with the 4 screw\
s. Torx wrench: T40 (Part No. 09042 −00020 or locally manufactured tool)
Torque: 21 N·m (210 kgf·cm, 15 ft·lbf)
(b) Connect the connector.
NOTICE:
Installation of the connector is done with the sensor assembly installed\
.
Make sure the sensor assembly is installed to the specified torque.
If the sensor assembly has been dropped, or there are cracks, dents or o\
ther defects in the
case, bracket or connector, replace the sensor assembly with a new one.
When installing the sensor assembly, take care that the SRS wiring does not interfere with other
parts and is not pinched between other parts.
After installation, shake the sensor assembly to check that there is no \
looseness.

SUPPLEMENTAL RESTRAINT SYSTEM WIRE HARNESS AND CONNECTOR
1996 LAND CRUISER (RM451U)
INSPECTION
HINT:
The SRS wire harness is integrated with the cowl wire harness assembly and \
floor wire harness assembly.
The wires for the SRS wire harness are encased in a black corrugated tube a\
nd all the connectors in the
system are a standard yellow color.
1. VEHICLES NOT INVOLVED IN COLLISION
Do a diagnostic system check (See page DI−240).
2. VEHICLES INVOLVED IN COLLISION
(a) Do a diagnostic system check (See page DI−240).
(b) Check for breaks in all wires of the SRS wire harness, and for exposed c\
onductors.
(c) Check to see if the SRS wire harness connectors are cracked or chipped.

TROUBLESHOOTING
PROBLEM SYMPTOMS TABLE
Use the table below to help you find the cause of the problem. The numbers \
indicate the priority of the likely
cause of the problem. Check each part in order. If necessary, replace these parts.
(w/ Differential locking system):
Check that center differential lock mode is set.
When switching differential Free↔Lock, the indicator lamp will blink if the gears of the differen-
tial lock sleeve are not meshed. If this occurs, when the tires are rotated \
to apply differential
power to the differential, the differential locks and the indicator lamp\
light up.
