1. Clear the DTC memory (see CLEAR THE DTC MEMORY WITH THE

HDS).

2. Turn the ignition switch ON (II), and check that the SRS indicator comes on

for about 6 seconds and then goes off.

Does the SRS indicator stay on, and is DTC 92-1x indicated?

YES -Go to step 3.

NO -Intermittent failure, system is OK at this time. Go to
TROUBLESHOOTING INTERMITTENT FAILURES. If another DTC is
indicated, troubleshoot the DTC.

3. Disconnect the passenger's airbag cutoff indicator 4P connector (see

PASSENGER'S AIRBAG CUTOFF INDICATOR ILLUMINATION
BULB TEST).

4. Turn the ignition switch OFF. Disconnect the negative cable from the battery,

then wait for 3 minutes.

5. Disconnect SRS unit connector A (28P) from the SRS unit (see step 8

DISCONNECTING SYSTEM CONNECTORS).

6. Reconnect the negative cable to the battery.
7. Turn the ignition switch ON (II).
8. Measure the voltage between the No. 13 terminal of SRS unit connector A

(28P) and body ground. There should be 0.5 V or less.

Precautions and Procedures (see PRECAUTIONS AND
PROCEDURES) and General Troubleshooting Information
(see GENERAL TROUBLESHOOTING INFORMATION).

then wait for 3 minutes.

5. Disconnect SRS unit connector A (28P) from the SRS unit (see step 8

DISCONNECTING SYSTEM CONNECTORS).

6. Measure the resistance between the No. 4 terminal of the passenger's airbag

cutoff indicator 4P connector and the No. 13 terminal of SRS unit connector A
(28P). There should be 0-1.0 ohms.

Is the resistance as specified?

YES -Go to step 7.

NO -Open in the dashboard wire harness; replace the dashboard wire harness.

7. Measure the resistance between the No. 13 terminal of the SRS unit connector

A (28P) and body ground. There should be an open circuit or at least 1 M
