Component Description
SDM (Sensing and Diagnostic Module)
WARNING:DURING SERVICE PROCEDURES, BE
VERY CAREFUL WHEN HANDLING A SENSING AND
DIAGNOSTIC MODULE (SDM). NEVER STRIKE OR
JAR THE SDM. NEVER POWER UP THE SRS WHEN
THE SDM IS NOT RIGIDLY ATTACHED TO THE
VEHICLE. ALL SDM AND MOUNTING BRACKETFASTENERS MUST BE CAREFULLY TORQUED AND
THE ARROW MUST BE POINTED TOWARD THE
FRONT OF THE VEHICLE TO ENSURE PROPER
OPERATION OF THE SRS. THE SDM COULD BE
ACTIVATED WHEN POWERED WHILE NOT RIGIDLY
ATTACHED TO THE VEHICLE WHICH COULD CAUSE
DEPLOYMENT AND RESULT IN PERSONAL INJURY.
The Sensing and Diagnostic Module (SDM) is designed
to perform the following functions in the SRS:

SUPPLEMENTAL RESTRAINT SYSTEM9J±11
Handling / Installation / Diagnosis
1. Air bag assembly should not be subjected to
temperatures above 93
C (200
F).
2. Air bag assembly, and SDM should not be used if they
have been dropped from a height of 100 centimeters
(3.28 feet) or more.
3. When a SDM is replaced, it must be oriented with the
arrow on the sensor pointing toward the front of the
vehicle. It is very important for the SDM to be located
flat on the mounting surface, parallel to the vehicle
datum line. It is important that the SDM mounting
surface is free of any dirt or other foreign material.
4. Do not apply power to the SRS unless all components
are connected or a diagnostic chart requests it, as this
will set a diagnostic trouble code.
5. The ªSRS Diagnostic System Checkº must be the
starting point of any SRS diagnostics. The ªSRS
Diagnostic System Checkº will verify proper ªAIR
BAGº warning lamp operation and will lead you to the
correct chart to diagnose any SRS malfunctions.
Bypassing these procedures may result in extended
diagnostic time, incorrect diagnosis, and incorrect
parts replacement.
Air Bag Assembly Handling /
Shipping / Scrapping
Live (Undeployed) Air Bag Assembly
Special care is necessary when handling and storing a
live (undeployed) air bag assembly. The rapid gas
generation produced during deployment of the air bag
could cause the air bag assembly, or an object in front of
the air bag assembly, to be thrown through the air in the
unlikely event of an accidental deployment.

Live (undeployed) pretensioner seat belt.
Special care is necessary when handling and storing a

The rapid gas generation produced during deployment of
the pretensioner seat belt (could cause the pretensioner
seat belt), or an object around of pretensioner seat belt, to
be thrown through the air in the unlikely event of an
accidental deployment.

Service Precautions for SRS
Component Service
CAUTION: When fasteners are removed, always
reinstall them at the same location from which they
were removed. If a fastener needs to be replaced, use
the correct part number fastener for that application.
If the correct part number fastener is not available, a
fastener of equal size and strength (or stronger) may
be used. fasteners that are not reused, and those
requiring thread locking compound will be called
out. The correct torque value must be used when
installing fasteners that require it. If the above
conditions are not followed, parts or system damage
could result.
WARNING: WHEN PERFORMING SERVICE ON OR
AROUND SRS COMPONENTS OR SRS WIRING,
FOLLOW THE PROCEDURES LISTED BELOW TO
TEMPORARILY DISABLE THE SRS. FAILURE TO
FOLLOW PROCEDURES COULD RESULT IN
POSSIBLE AIR BAG DEPLOYMENT, PERSONAL
INJURY OR OTHERWISE UNNEEDED SRS REPAIRS.
The SDM in Driver±Passenger SRS can maintain
sufficient voltage to cause a deployment for up to 15
seconds after the ignition switch is turned ªOFF,º the
battery is disconnected, or the fuse powering the SDM is
removed.
Many of the service procedures require removal of the
ªC±21º fuse, and disconnection of the air bag assembly
from the deployment loop to avoid an accidental
deployment. If the air bag assembly is disconnected from
the deployment loop as noted in the ªDisabling the SRSº
procedure that follows, service can begin immediately
without waiting for the 15 second time period to expire.
Disabling The SRS
Removal
Turn the ignition switch to ªOFFº and turn the steering
wheel so that the vehicle's wheels are pointing straight
ahead.
1. Remove SRS fuse ªC±21º from left dash side lower
fuse block or disconnect battery.
2. Disconnect yellow 2±pin connector at the base of
steering column.
3. Remove glove box assembly; Refer to ªPassenger air
bag assembly replacementº in this section.
4. Disconnect passenger air bag assembly yellow 2±pin
connector behind the glove box assembly.
CAUTION: W i t h t h e ª C±21º fuse removed and
ignition switch ªON,º the ªAIR BAGº warning lamp
will be ªON.º This is normal operation and does not
indicate an SRS malfunction.
Enabling The SRS
Installation
Turn ignition switch to ªLOCKº and remove key.
1. Connect yellow 2±pin connector passenger air bag
assembly.2. Install glove box assembly. Refer to ªPassenger Air
Bag Assembly Replacementº in this section.
3. Connect yellow 2±pin connector at the base of the
steering column.
4. Install ªAIR BAGº fuse ªC±21º to left dash side lower
fuse block or connect battery.
Turn ignition switch to ªONº and verify that the ªAIR BAGº
warning lamp turn on 3.5 seconds and then turns ªOFF.º If
it does not operate as described, perform the ªSRS
Diagnostic System Checkº in this section.
Handling / Installation / Diagnosis
1. Air bag assembly should not be subjected to
temperatures above 93
C (200
F).
2. Air bag assembly, and SDM should not be used if they
have been dropped from a height of 100 centimeters
(3.28 feet) or more.
3. When a SDM is replaced, it must be oriented with the
arrow on the SDM pointing toward the front of the
vehicle. It is very important for the SDM to be located
flat on the mounting surface, parallel to the vehicle
datum line. It is important that the SDM mounting
surface is free of any dirt or other foreign material.
4. Do not apply power to the SRS unless all components
are connected or a diagnostic chart requests it, as
this will set a diagnostic trouble code.
5. The ªSRS Diagnostic System Checkº must be the
starting point of any SRS diagnostics. The ªSRS
Diagnostic System Checkº will verify proper ªAIR
BAGº warning lamp operation and will lead you to the
correct chart to diagnose any SRS malfunctions.
Bypassing these procedures may result in extended
diagnostic time, incorrect diagnosis, and incorrect
parts replacements.
Inspections Required After An Accident
CAUTION: C e r t a i n S R S c o mponents must be
replaced after a frontal crash involving air bag
deployment.
In all types of accidents regardless of ªAir Bagº
deployment, visually inspect all of the following
components and replace as required:
Ð Driver air bag assembly
Ð Passenger air bag assembly
Ð Driver pretensioner assembly
Ð Passenger pretensioner assembly
Ð Steering wheel
Ð SRS coil assembly
Ð Steering column
Ð Knee bolster and instrument panel mounting
attachments
Ð Driver seat and belt
Ð Passenger seat and belt
Ð SDM
SDM always should be checked according to ªSDM
Replacement Guidelines.º

Service Precautions
WARNING:DURING SERVICE PROCEDURES, BE
VERY CAREFUL WHEN HANDLING SDM. NEVER
STRIKE OR JAR SDM. UNDER SOME
CIRCUMSTANCES, IT COULD CAUSE
DEPLOYMENT AND RESULT IN PERSONAL INJURY
OR IMPROPER OPERATION OF THE
SUPPLEMENTAL RESTRAINT SYSTEM (SRS) . SDM
MOUNTING BRACKET BOLTS MUST BE
CAREFULLY TORQUED TO ASSURE PROPER
OPERATION. NEVER POWER UP THE SRS WHEN
SDM IS NOT RIGIDLY ATTACHED TO THE VEHICLE.
THE SDM COULD BE ACTIVATED WHEN POWERED
WHILE NOT RIGIDLY ATTACHED TO THE VEHICLE
WHICH COULD CAUSE DEPLOYMENT AND RESULT
IN PERSONAL INJURY.
WARNING: PROPER OPERATION OF THE SENSING
AND DIAGNOSTIC MODULE (SDM) REQUIRES THE
SDM TO BE RIGIDLY ATTACHED TO THE VEHICLE
STRUCTURE AND THAT THE ARROW ON THE
SENSOR BE POINTING TOWARD THE FRONT OF
THE VEHICLE.
SDM is specifically calibrated and is keyed to the SDM
location SRS wiring harness. Caution should be used to
ensure proper location of the SDM. The keying of the
SDM to its location and wiring harness connectors should
never be modified in the field.
Removal
1. Disable the SRS (Refer to ªDisabling the SRSº in this
section).
2. Remove the transmission knob (for M/T) and transfer
lever knob.
3. Remove the front console assembly and disconnect
wiring harness connector.
4. Pull CPA (Connector Position Assurance) out and
push connector lock down to disconnect the SDM
harness connector.
5. Remove the three SDM fixing bolts and remove SDM.
