cluster. If battery is not present, check for open in driver-side under-dash fuse/relay box fuse No. 21
circuit, open in Yellow wire of instrument cluster wire harness or in left side wire harness. If driver-side
under-dash fuse/relay box is okay, replace appropriate wire harness.

8. Replace fuse No. 21. Turn ignition on and recheck AIR BAG warning light. If warning light illuminates,

system is okay at this time. If warning light does not illuminate, check for short to ground in driver-side
under-dash fuse/relay box fuse No. 21 line. Repair or replace as necessary.

AIR BAG WARNING LIGHT STAYS ON

1. Before proceeding, see AIR BAG SAFETY PRECAUTIONS . Retrieve DTCs. See RETRIEVING

DIAGNOSTIC TROUBLE CODE (DTC) under DIAGNOSTICS. If DTCs no are retrieved, go to next
step. If DTCs are retrieved, go to appropriate DTC to continue diagnosis. See DIAGNOSTIC
TROUBLE CODE (DTC) CHART table.

2. Disable air bag system. See DISABLING SYSTEM under DISABLING & ACTIVATING AIR BAG

SYSTEM. Access and disconnect SRS unit connector "A". See SRS UNIT under REMOVAL &

INSTALLATION. Access and disconnect instrument cluster connector "A". See INSTRUMENT
CLUSTER under REMOVAL & INSTALLATION.

3. Measure resistance between instrument cluster connector "A", terminal No. 7 (Pink wire) and SRS unit

connector "A" terminal No. 19 (Blue wire). See Fig. 32 & Fig. 33 . If resistance is less than one ohm, go
to next step. If resistance is more than one ohm, check both connectors for poor connection. If connection
is okay, replace dashboard wire harness.

4. Reconnect battery. Reconnect instrument cluster harness connectors. Turn ignition on. Install jumper wire

between instrument cluster connector "A", terminals No. 7 and 10. If AIR BAG warning light turns off,
check for faulty at SRS unit connector "A". If connector and connection is okay, replace SRS unit. If AIR
BAG warning light does not turn off, check for faulty connection at instrument cluster connector "A". If
connector and connection is okay, replace instrument cluster.

SIDE AIR BAG WARNING LIGHT STAYS ON AFTER BULB CHECK

Before proceeding, see AIR BAG SAFETY PRECAUTIONS . Ensure nothing is on right front seat. If side
AIR BAG warning light stays on after ignition switch is turned to ON position, initialize Occupant Position
Detection System (OPDS) unit. See INITIALIZING OCCUPANT POSITION DETECTION SYSTEM
(OPDS) UNIT under DIAGNOSTICS. If after initializing OPDS unit, side AIR BAG warning light stays on,
replace OPDS sensor, located in seat back pad. If after initializing OPDS unit, side AIR BAG warning light
operates normally, system is functioning normally at this time. Also, check for DTC 87-31, 87-32 .

SIDE AIR BAG WARNING FLASHING

Before proceeding, see AIR BAG SAFETY PRECAUTIONS . Ensure nothing is on right front seat. If side
AIR BAG warning light stays on after ignition switch is turned to ON position, initialize Occupant Position
Detection System (OPDS) unit. See INITIALIZING OCCUPANT POSITION DETECTION SYSTEM
(OPDS) UNIT under DIAGNOSTICS. If after initializing OPDS unit, side AIR BAG warning light stays on,
replace OPDS sensor, located in seat back pad. If after initializing OPDS unit, side AIR BAG warning light
operates normally, system is functioning normally at this time. Also, check for DTC 87-31, 87-32 .

DTC 11-1, 11-4

1. Before proceeding, see AIR BAG SAFETY PRECAUTIONS . Erase Diagnostic Trouble Code (DTC)

memory. See ERASING DIAGNOSTIC TROUBLE CODE MEMORY under DIAGNOSTICS. Turn
ignition switch to ON position and check that AIR BAG warning light comes on for about 6 seconds and
then goes off. If AIR BAG warning light stays on, go to next step. If AIR BAG warning light goes off
after about 6 seconds, system is okay at this time. Check for intermittent malfunction. See
TROUBLESHOOTING INTERMITTENT FAILURES under DIAGNOSTICS.

2. Turn ignition switch to OFF position. Disable air bag system. See DISABLING SYSTEM under

DISABLING & ACTIVATING AIR BAG SYSTEM. Disconnect driver-side air bag module connector
from upper cable reel connector. See Fig. 4 . Connect SRS Simulator Lead (07XAZ-SZ30100) and SRS
Inflator Simulator (07SAZ-TB4011A) to upper cable reel connector. Reconnect negative battery cable.
Erase DTC memory. Retrieve DTC. See RETRIEVING DIAGNOSTIC TROUBLE CODE (DTC)
under DIAGNOSTICS. If DTC 11-1 or 11-4 is indicated, go to next step. If DTC 11-1 or 11-4 is not
indicated, replace driver-side air bag. See DRIVER-SIDE AIR BAG MODULE under REMOVAL &
INSTALLATION.

3. Turn ignition switch to OFF position. Disable air bag system. Disconnect dashboard wire harness

connector from lower cable reel connector. Connect SRS simulator lead and SRS inflator simulator to
dashboard wire harness connector. Reconnect negative battery cable. Erase DTC memory. Retrieve DTC.
If DTC 11-1 or 11-4 is indicated, go to next step. If DTC 11-1 or 11-4 is not indicated, replace cable reel.
See CABLE REEL under REMOVAL & INSTALLATION.

4. Turn ignition switch to OFF position. Disable air bag system. Access and disconnect SRS unit harness

connector "A" from SRS unit. See SRS UNIT under REMOVAL & INSTALLATION. See Fig. 33 .
Disconnect SRS inflator simulator from simulator lead. DO NOT disconnect simulator lead from
dashboard wire harness connector. Measure resistance between each pair of SRS inflator simulator
connector terminals. If resistance is less than one ohm, check connection between SRS unit connector
"A" and SRS unit. If connection is okay, replace SRS unit. If resistance is more than one ohm, replace
appropriate wire harness. See WIRING DIAGRAMS .
