INSPECTION
1. INSPECT STEERING LOCK OPERATION
Check that the steering lock mechanism operates properly.
2. IF NECESSARY, REPLACE KEY CYLINDER
(a) Turn the ignition key to the ACC position.
(b) Push down the stop pin with a screwdriver, and pull out
the cylinder.
(c) Install a new cylinder.
HINT:
Make sure that the key is in the ACC position.
3. INSPECT IGNITION SWITCH (See page BE±24)
4. IF NECESSARY, REPLACE IGNITION SWITCH
(a) Remove the 2 screws and ignition switch.
(b) Install a new ignition switch with the 2 screws.
5. INSPECT KEY UNLOCK WARNING SWITCH
(See page BE±24)
6. IF NECESSARY, REPLACE KEY UNLOCK WARNING
SWITCH
(a) Slide out the key unlock warning switch.
(b) Install a new key unlock warning switch.
7. INSPECT TRANSPONDER KEY COIL
(See page BE±143)
8. IF NECESSARY, REPLACE TRANSPONDER KEY
COIL
9. IF NECESSARY, REPLACE TRANSPONDER KEY AM-
PLIFIER
(a) Remove the screw and transponder key amplifier.
(b) Install a new transponder key amplifier with the screw.
10. INSPECT BEARING
(a) Check that the bearing rotates smoothly without abnor-
mal noise.
If it does not rotate smoothly or abnormal noise occurs, replace
the column housing.
(b) Coat the bearing with molybdenum disulfide lithium base
grease.

± SUPPLEMENTAL RESTRAINT SYSTEMSRS AIRBAG
3285 Author: Date:
2005 SEQUOIA (RM1146U)
If the steering wheel pad, front passenger airbag assembly, side airbag assembly, curtain
shield airbag assembly, airbag sensor assembly, front airbag sensor, side airbag sensor as-
sembly, curtain shield airbag sensor assembly, seat position sensor assembly or occupant
classification ECU has been dropped, or if there are any cracks, dents or other defects in the
case, bracket or connector, replace it with a new one.
Use a volt/ohmmeter with high impedance (10 kW/V minimum) for troubleshooting the electrical
circuits.
Information labels are attached to the periphery of the SRS components. Follow the instruc-
tions in the caution.
After work on the SRS is completed, perform the SRS warning light check (see page DI±1137).
When the negative (±) terminal cable is disconnected from the battery, the memory will be
cleared. Because of this, be sure to make a record of the contents memorized in each system
before starting work. When work is finished, adjust each system as it was before. Never use
a back±up power supply from outside the vehicle to avoid erasing the memory in any system.

4. SIDE AIRBAG ASSEMBLY
The inflator and bag of the SRS are stored in the side airbag as-
sembly and cannot be disassembled. The inflator contains a
squib, igniter charge and gas generator, etc., and inflates the
bag when instructed by the airbag sensor assembly. The side
airbag assembly cannot be disassembled.
5. CURTAIN SHIELD AIRBAG ASSEMBLY
The inflator and bag of the SRS are stored in the curtain shield
airbag assembly and cannot be disassembled. The inflator con-
tains a squib, igniter charge, gas generator, etc., and inflates
the bag when instructed by the airbag sensor assembly. The
curtain shield airbag assembly cannot be disassembled.
6. SEAT BELT PRETENSIONER
The front seat outer belt has the seat belt pretensioner system.
The pretensioner operates in the event of a frontal collision. The
seat belt pretensioner cannot be disassembled.
7. SRS WARNING LIGHT
The SRS warning light is located on the combination meter. It
comes on to alert the driver of trouble in the system when a mal-
function is detected in the airbag sensor assembly. In normal
operation conditions when the ignition switch is turned to the
ON position, the light comes on for approximately 6 seconds
and then goes off.
8. AIRBAG SENSOR ASSEMBLY
The airbag sensor assembly is mounted on the floor inside the
lower center finish panel. The airbag sensor assembly consists
of an airbag sensor, safing sensor, diagnosis circuit, ignition
control, drive circuit, etc. It receives signals from the airbag sen-
sor, front airbag sensor, side and curtain shield airbag sensor
and curtain shield airbag sensor, and judges whether the SRS
must be activated or not. The airbag sensor assembly cannot
be disassembled.
