An alpha character (A-F) or numeric character (0-9) may follow DTC. This character is unrelated to
troubleshooting; it designates SRS unit manufacturer and other details used for product analysis.

(2)

Clear DTCs. Turn ignition switch to ON position. If AIR BAG warning light stays ON, replace
appropriate impact sensor. If AIR BAG warning light does not stay on, check for intermittent
problem. See TROUBLESHOOTING INTERMITTENT FAILURES .

(3)

Before replacing SRS unit, ensure battery is fully charged. Clear DTCs. Turn ignition switch to ON
position. If AIR BAG warning light stays ON, replace SRS unit. If AIR BAG warning light does not

DIAGNOSTIC TESTS

AIR BAG WARNING LIGHT DOES NOT COME ON

1. Before proceeding, see AIR BAG SAFETY PRECAUTIONS . Turn ignition on, and check whether

other indicator lights come on or not (brake system, etc.). If other indicator lights do not operate, go to
step 5 . If other indicator lights operate, go to next step.

2. Turn ignition off. Access instrument cluster. See INSTRUMENT CLUSTER under REMOVAL &

INSTALLATION. Disconnect instrument cluster connectors "A" and "B". See Fig. 32 . Measure
resistance between ground and instrument cluster connector "A", terminal No. 18 (Black wire). If
resistance is 0-1.0 ohm, go to next step. If resistance is not 0-1.0 ohm, check for open in Black wire or
faulty ground terminal. See WIRING DIAGRAMS . If ground terminal is okay, replace appropriate wire
harness.

3. Reconnect negative battery, if disconnected. Connect voltmeter between ground and instrument cluster

connector "A", terminal No. 7 (Pink wire). Turn ignition on and observe voltmeter. Voltage should be one
volt for first 6 seconds, then more than 11 volts. If voltage is not as specified, go to next step. If voltage is
as specified, replace instrument cluster.

4. Turn ignition off. Access SRS unit. See SRS UNIT under REMOVAL & INSTALLATION. Disconnect

SRS unit connector "A". See Fig. 33 . Connect voltmeter between ground and instrument cluster
connector "A", terminal No. 7. (Pink wire). Turn ignition on. If voltage is less than 0.5 volt, replace SRS
unit. If voltage is more than 0.5 volt, check for short to voltage in Pink wire or junction connector.
Replace appropriate wire harness.

5. Turn ignition off. Check fuse No. 21 (7.5-amp) in under-dash fuse/relay box. If fuse is blown, go to step

8 . If fuse is okay, go to next step.

6. Connect voltmeter between ground and instrument cluster connector "A", terminal No. 10 (Yellow wire).

Turn ignition on and observe voltmeter. Go to next step.

7. If battery voltage is present, check for faulty SRS indicator circuit in instrument cluster or poor contact at

instrument cluster connector "A" and instrument cluster. If connections are okay, replace instrument

stay on, check for intermittent problem. See TROUBLESHOOTING INTERMITTENT
FAILURES .

(4)

Replace Occupant Position Detection System (OPDS) unit. See OCCUPANT POSITION
DETECTION SYSTEM (OPDS) UNIT under REMOVAL & INSTALLATION.

(5)

Perform Occupant Position Detection System (OPDS) unit initialization procedure. See
INITIALIZING OCCUPANT POSITION DETECTION SYSTEM (OPDS) UNIT under
DIAGNOSTICS.

(6)

SRS unit must be replaced if any air bags and/or pretensioners have deployed.

WARNING:

Accidental air bag deployment is possible. Personal injury may result.
Read and follow all WARNINGS and AIR BAG SAFETY PRECAUTIONS
before working on air bag system or related components.
Bumping SRS unit can cause air bags to accidently deploy. Personal
injury may result. Whenever ignition is on, or has been turned off for less
than 3 minutes, be careful not to bump SRS unit
