GENERAL DESCRIPTION
AND SYSTEM OPERATION
STEERING WHEEL AND COLUMN
CAUTION : To ensure the energy–absorbing action of
the steering column, it is important to use only the
specified screws, bolts, and nuts, tightened to the
specified torque.
In addition to the steering function, the steering column
provides safety and security.
The energy–absorbing column is designed to compress in
a front–end collision to lessen the chance of driver injury.
The ignition switch and the lock are mounted on the col-
umn, allowing the ignition and steering operations to be
locked to inhibit theft of the car.
The column levers trigger the turn signals, the headlight
beams, and the windshield washer and wipers.The tilt steering column uses telescopic function to allow
the steering wheel to tilt up and down in and out. This en-
ables the driver to adjust the steering wheel to a comfort-
able position.
Notice : Apply a thin coat of lithium grease to all friction
points when reassembling.
The column may be disassembled and reassembled easi-
ly.IGNITION KEY REMINDER
The ignition key reminder alerts the driver that the key is
still in the ignition when the driver attempts to exit the ve-
hicle.
An internal switch in the ignition lock cylinder supplies bat-
tery voltage to the reminder chime module when all of the
following conditions are true:
S The key is in the ignition switch.
S The ignition is OFF.
S The driver’s door is open.
For information on removal and installation of the reminder
chime module, refer to Section 9E, Instrumentation/Driver

SIR DIAGNOSTIC SYSTEM CHECK
Notice : If the vehicle interior has been exposed to exten-
sive water intrusion such as water leaks, driving through
high water, flooding, or other causes, the sensing and
diagnostic module(SDM) and SDM connector may need
to be replaced. With ignition OFF, inspect the area around
the SDM, including the carpet. If any significant soaking or
evidence of previous soaking is detected, the water must
be removed, water damage repaired, and the SDM and
the SDM connector must be replaced. Before attempting
any of these repairs, the supplemental inflatable re-
straints(SIR) must be disabled. Refer to ”Disabling the
SIR” and ”Sensing and Diagnostic Module(SDM)” in this
section for instructions on how to disable the SIR and re-
place the SDM.
The SIR Diagnostic System Check must always be the
starting point for any SIR diagnosis. The Diagnostic Sys-
tem Check reveals diagnostic trouble codes(DTCs)
through the use of scan tool. The diagnostic procedures
used in this section are designed to find any repair SIR
conditions. To get the best results, it is important to use the
diagnostic charts and follow the sequence listed below.
1. Perform the SIR Diagnostic System Check, which
reveal diagnostic trouble codes(DTCs) through theuse of scan tool.. It also checks for proper airbag
indicator operation.
2. Refer to the proper diagnostic chart as directed by
SIR Diagnostic System Check. Bypassing these
procedures may result in extended diagnostic time,
incorrect diagnosis, and incorrect parts replace-
ment.
3. Repeat the SIR Diagnostic System Check after any
repair or diagnostic procedures have been per-
formed to ensure that the repair has been made
correctly and that no other malfunction exists.
Circiut Description
When the ignition switch is first turned to ON, ignition volt-
age is supplied from airbag fuse to find the SDM at input
terminal A1. The SDM responds by flashing the airbag in-
dicator seven times and then turning it off while the SDM
performs tests on the SIR.
Diagnostic Aids
The order in which DTCs are diagnosed is very important.
Failure to diagnose the DTCs in the order specified may
result in extended diagnostic time, incorrect diagnosis,
and incorrect parts replacement.
SIR Diagnostic System Check
CAUTION : The sensing and the diagnosis module
(SDM) can maintain surfficient voltage to deploy the
airbags and pretensioners for 1 minute after the igni-
tion is OFF and the fuse has been removed. If the air-
bags and pretensioners are not disconnected, do not
begin service until one minute has been passed after
disconnecting power to the SDM. Otherwise, injury
could result.
CAUTION : During service procedure, be very careful
when handling the SDM. Never strike or jar the SDM.Never power the supplemental inflatable re-
straints(SIR) when the SDM is not rigidly attached to
the vehicle. All SDM mounting bolts must be carefully
tightened , and the arrow on the SDM must be point
toward the front of the vehicle to ensure proper op-
eration of the SIR. The SDM could be activated if it is
powered when it is not rigidly attached to the vehicle,
resulting in unexpected deployment and possible in-
jury.

SENSING AND DIAGNOSTIC MODULE (SDM) INTEGRITY
CHECK
The following diagnostic chart must be used when all cir-
cuitry outside the sensing and diagnostic module (SDM)
has been found to operate properly, as indicated by follow-
ing the appropriate diagnostic trouble code(DTC) chart.
The chart verifies the need for SDM replacement.
Circuit Description
When the SDM recognizes ignition voltage greater than 9
volts at terminal A1 of the SDM, the airbag indicator
flashes seven times to verify operation. At this time the
SDM performs turn–on tests followed by resistance mea-surement tests and continuous monitoring tests.
When malfunction is detected, the SDM sets current DTC
and illuminates the airbag indicator.
When the malfuncation is no longer detected and/or the
ignition switch is cycled, the SDM will clear current DTCs
and move them to a history file, except for the DTCs 51
and sometimes 71. DTCs 51 will not be cleared by scan
tool because these codes require replacement of SDM.
The SDM must be replaced only after the malfunction that
set the DTC has been repaired.
Sensing and Diagnostic Module (SDM) Integrity Check
CAUTION : The sensing and diagnostic module
(SDM) can maimtain sufficient voltage to deploy the
airbags and pretensioners for 1 minute after the igni-
tion is OFF and the fuse has been removed. If the air-
bags and pretensioners are not disconnected, do not
begin service until one minute has passed after dis-
connecting the power to the SDM. Otherwise, injury
could result.
CAUTION : During service procedure, be very careful
when handling the SDM. Never strike or jar the SDM.Never power the supplemental inflatable re-
straints(SIR) when the SDM is not rigidlyattached to
the vehile. All SDM mounting bolts must be carefully
tightened , and the arrow on the SDM must be point
toward the front of the vehicle to ensure proper op-
eration of the SIR. The SDM could be activated if it is
powered when it is not rigidly attached to the vehicle,
resulting in unexpected deployment and possible in-
jury.
