CAUTION:
Never turn steering wheel while steering lower shaft assem-
bly is removed.
Should it have been turned and contact coil (on combina-
tion switch) have got out of its centered position, it needs
to be centered again. Also, turning steering wheel more
than about two and a half turns will break contact coil.
REMOVAL
1) Turn steering wheel so that vehicle's front tires are at straight-
ahead position.
2) Turn ignition switch to ªLOCKº position and remove key.
3) After removing bolt on column side of shaft joint and loosening
bolt on its lower shaft assembly side, move shaft joint to lower
shaft assembly side (in arrow direction in figure).
4) Remove lower shaft assembly lower joint bolt and then remove
lower shaft assembly.
5) Remove shaft joint bolt (lower shaft assembly side) from shaft
joint and then remove shaft joint from lower shaft assembly.

8G-2 IMMOBILIZER CONTROL SYSTEM (IF EQUIPPED)
GENERAL DESCRIPTION
The immobilizer control system designed to prevent vehicle burglar consists of following components.

Engine control module (ECM) / Powertrain control module (PCM)

Immobilizer control module

Ignition key (with built-in transponder)

Coil antenna
Operation of this system is as follows.
(1) Each ignition key has its own code (Transponder code) stored in memory. When the ignition switch is turned
ON, Immobilizer Control Module tries to read the Transponder code through the coil antenna installed to the
steering lock assembly.
(2) Immobilizer Control Module compares the Transponder code read in (1) and that registered in Immobilizer Con-
trol Module and checks if they match.
(3) When it is confirmed that two Transponder codes match each other as described above, Immobilizer Control
Module and ECM / PCM check if ECM/Immobilizer Control Module codes registered in them respectively match.
(4) Only when it is confirmed that ECM/Immobilizer Control Module codes match, the engine starts running. If
Transponder codes in Step (2) or ECM/Immobilizer Control Module codes in Step (3) do not match, ECM / PCM
will stop operation of the injector and ignition of spark plug.

IGNITION KEY
The ignition key for the immobilizer control system has a built-in
transponder. Each transponder in the key has an each transmitting
code (Transponder code). The code will transmitted from the key
via the coil antenna to Immobilizer Control Module when the ignition
switch is turned ON.
COIL ANTENNA
The coil antenna is installed to the steering lock assembly. As it is
energized by Immobilizer Control Module, it transmits the trans-
ponder code of the ignition key to Immobilizer Control Module.

AIR BAG SYSTEM 10B-7
Special Tool (Air Bag Driver/Passenger Load Tool)
(B): 09932-75010
This tool is used only when called for in this section. It is used as
a diagnostic aid and safety device to prevent inadvertent air bag (in-
flator) module deployment and seat belt pretensioner activation.
The load tool has three connectors attached to its case are electri-
cally functional and serve as resistive load substitutions.
No more than two connectors are used at any time.
One of connectors (ªAº: BASE OF COLUMN) is used to substitute
the load of the driver air bag (inflator) module and the contact coil
assembly when it is connected at the base of the column to the air
bag wire harness.
Another connector (ªBº: STEERING WHEEL) is used to substitute
the load of followings.

Driver air bag (inflator) module when it is connected at the top of
the column to the contact coil assembly.

Passenger air bag (inflator) module when it is connected to the
air bag harness connector for passenger air bag (inflator) module.

Driver and passenger seat belt pretensioner when it is connected
to air bag harness connector for driver and passenger seat belt
pretensioner.
The third connector (ªCº: PASSENGER INFLATOR) is not used.
By substituting the resistance of the load tool when called for, a de-
termination can be made as to whether an inflator circuit compo-
nent is causing system malfunction and which component is caus-
ing the malfunction.
The load tool should be used only when specifically called for in the
diagnostic procedures.

CAUTION:

When measurements are requested in this chart use specified digital multimeter with correct terminal
adapter from special tool (Connector test adapter kit).

When a check for proper connection is requested refer to ªIntermittents and Poor Connectionsº in
this section.

When an open in air bag wire harness, damaged wire harness, connector or terminal is found, replace
wire harness, connectors and terminals as an assembly.
DTC WILL SET WHEN:
The combined resistance of the driver air bag (inflator) module, contact coil assembly, harness wiring and connec-
tor terminal contact is above a specified value for specified time.
NOTE:
Before executing items in this table, be sure to perform ªAir Bag Diagnostic Check Flow Tableº.
STEP
ACTIONYESNO
11) With ignition switch OFF, disconnect contact
coil connector located near the base of the
steering column.
2) Check proper connection to contact coil at
terminals in ªCº connector.
3) If OK then connect Special Tool (B) to contact
coil connector disconnected at step 1).
4) With ignition switch ON, is DTC 21 current?Go to step 2.Go to step 3 on the
next page.
21) With ignition switch OFF, disconnect SDM.
2) Check proper connection to SDM at terminals
ªA6º and ªA7º.
3) Release shorting bar in SDM connector,
referring to the figure below.
4) If OK then measure resistance between ªA6º
and ªA7º terminals with connected Special Tool
(B).
5) Is resistance 3.5
or less?Substitute a known-
good SDM and
recheck.Repair high resistance
