2) Tighten fasteners to spec. See TORQUE SPECIFICATIONS.
Activate SRS. See DISABLING & ACTIVATING AIR BAG SYSTEM . Check AIR BAG
warning light for proper system function. SYSTEM OPERATION CHECK.
PASSENGER-SIDE AIR BAG MODULE
Removal & Installation
1) Before proceeding, see SERVICE PRECAUTIONS. Deactivate
SRS. See DISABLING & ACTIVATING AIR BAG SYSTEM .
2) Remove right-side foot shower duct and two stoppers on
either side. Remove and lower glove box. Disconnect air bag module
connector. Remove retaining bolts and passenger-side air bag module.
See Fig. 5 .
3) To install, reverse removal procedure. Tighten bolts to

CLOCKSPRING CENTERING
WARNING: If front wheels are not in straight-ahead position or
clockspring mating marks are not aligned before installing
clockspring, the steering wheel may not turn completely, or
flat cable inside clockspring may be severed, disabling SRS
system and possibly causing serious injury to driver.
With clockspring removed, ensure front wheels are in
straight-ahead position. Turn clockspring fully clockwise, and then
turn it back approximately 3.3 turns counterclockwise to align mating
marks. See Fig. 8.

DIAGNOSIS & TESTING
INITIAL SRS DIAGNOSTIC PROCEDURE
WARNING: Follow air bag service precautions to prevent accidental air
bag deployment and personal injury. See SERVICE PRECAUTIONS.
NOTE: Ensure battery is fully charged. If battery voltage is too
low, SRS warning light will come on. When battery voltage is
restored to normal, light will go out. Codes remain stored
for no more than about 7 days. Codes can be stored no more
than 250 times. After servicing, reconnect negative battery
cable. Erase codes using Multi-Use Tester II (MUT-II,
MB991502). Check SRS warning light to verify system
operation. See SYSTEM OPERATION CHECK.
CAUTION: Ensure ignition is off before connecting or disconnecting
scan tool at DLC.
1) Before proceeding, follow service precautions. See
SERVICE PRECAUTIONS . Turn ignition on. If SRS warning light comes on
for about 7 seconds and turns off, SRS is functioning properly at this
time.
2) If SRS warning light does not come on, or comes on and
stays on, turn ignition switch to LOCK position. Connect scan tool to
Data Link Connector (DLC). See Fig. 9. Turn ignition on. Use scan tool
to retrieve code(s).

NOTE: Refer to WIRING DIAGRAMS for connector identification.
1) Before proceeding, see SERVICE PRECAUTIONS. Deactivate
SRS. See DISABLING & ACTIVATING AIR BAG SYSTEM .
2) Check front impact sensor, and replace if necessary. See
FRONT IMPACT SENSORS under REMOVAL & INSTALLATION. Measure SRS Check
Harness (MB991613) connector No. 5. Disconnect SRS-ECU connector C-122\
and connect SRS check harness connector No. 3 to C-122. Measure
resistance between terminals for normal value of 1,900-2,100 ohms. If
resistance is not as specified, go to next step. If resistance is as
specified, check for trouble symptoms. If fault exists, replace SRS-
ECU. See SRS AIR BAG CONTROL UNIT (ECU) under REMOVAL & INSTALLATION.
3) Check connector A-71, A-75, C-113, and C-122, and repair
if necessary. If connectors are okay, check for trouble symptoms. If
fault exists, inspect harness between SRS-ECU and front impact sensor,
and replace harness if necessary.
DTC 14: ANALOG "G" SENSOR SYSTEM
Before proceeding, see SERVICE PRECAUTIONS. Replace SRS-ECU.
See SRS AIR BAG CONTROL UNIT (ECU) under REMOVAL & INSTALLATION.
DTC 15 & 16: SAFING "G" SENSOR SYSTEM
Before proceeding, see SERVICE PRECAUTIONS. Replace SRS-ECU.
See SRS AIR BAG CONTROL UNIT (ECU) under REMOVAL & INSTALLATION.
DTC 21, 22 & 61: DRIVER-SIDE AIR BAG MODULE (SQUIB) SYSTEM
WARNING: During the following procedure, never measure circuit
resistance of air bag module (squib), even when using
specified DVOM. If circuit resistance is measured, it may
cause accidental air bag deployment and personal injury.
NOTE: Refer to WIRING DIAGRAMS for connector identification.
1) Before proceeding, see SERVICE PRECAUTIONS. Deactivate
SRS. See DISABLING & ACTIVATING AIR BAG SYSTEM .
2) Perform clockspring test, and repair as necessary. See
CLOCKSPRING TEST under COMPONENT TESTING. Disconnect clockspring
connector C-129. Connect SRS Check Harness (MB991613) connector No. 1
to clockspring connector. Connect negative battery cable. Erase DTC
memory and check if DTCs 21, 22, or 61 are set. If any of these DTCs
are output, go to next step. If DTCs are not output, go to step 4).
3) Check SRS-ECU connector C-122 and clockspring connector C-
129, and repair as necessary. If connectors are okay, check for
trouble symptoms. If fault exists, check harness between SRS-ECU and
clockspring. Disconnect connector C-122 and C-129. Connect SRS Check
Harness connector No. 1 to C-129 and No. 3 to C-122. Check resistance
between terminals No. 5 and 6. If resistance is approximately 3 ohms,
replace SRS-ECU. See SRS AIR BAG CONTROL UNIT (ECU) under REMOVAL &
INSTALLATION. If resistance is not as specified, repair as necessary.
4) Check connector C-129 and 1 (air bag module connector),
and repair if necessary. If connectors are okay, check trouble
symptoms. If fault exists, replace driver-side air bag module. See
DRIVER-SIDE AIR BAG MODULE under REMOVAL & INSTALLATION.
DTC 24, 25 & 64: PASSENGER-SIDE AIR BAG MODULE (SQUIB) SYSTEM
WARNING: During the following procedure, never measure circuit
resistance of air bag module (squib), even when using
specified DVOM. If circuit resistance is measured, it may

meter.
Light Does Not Turn Off
1) Before proceeding, see SERVICE PRECAUTIONS. Connect
negative battery cable and turn ignition switch to ON position. If SRS
warning light stays on when C-122 is disconnected, go to next step. If
SRS warning light turns off when C-122 is disconnected, replace SRS-
ECU. See SRS AIR BAG CONTROL UNIT (ECU) under REMOVAL & INSTALLATION.
2) Check connector C-122, and repair if necessary. If
connector is okay, check trouble symptoms. If fault still exists,
check wire harness between SRS-ECU and combination meter, and repair
if necessary.
DTC 44: SRS WARNING LIGHT DRIVE CIRCUIT SYSTEM
NOTE: If vehicle condition returns to normal, DTC will be erased
and SRS warning light will return to normal.
Before proceeding, see SERVICE PRECAUTIONS. Check SRS warning
light drive circuit system. If warning light drive system is okay,
replace SRS-ECU. See SRS AIR BAG CONTROL UNIT (ECU) under REMOVAL &
INSTALLATION. Check for DTCs. See SYSTEM OPERATION CHECK.
DTC 45: SRS-ECU EEPROM & A/D CONVERTER SYSTEM
Before proceeding, see SERVICE PRECAUTIONS. Replace SRS-ECU.
See SRS AIR BAG CONTROL UNIT (ECU) under REMOVAL & INSTALLATION.

COMPONENT TESTING
CLOCKSPRING TEST
1) Before proceeding, see SERVICE PRECAUTIONS. Deactivate
system. See DISABLING & ACTIVATING AIR BAG SYSTEM .
2) Remove driver-side air bag module and clockspring. See
DRIVER-SIDE AIR BAG MODULE & CLOCKSPRING under REMOVAL & INSTALLATION.
Check connectors, protective tubing, and case for damage, and
