DTC 92-2x (92-20 to 92-29, 92-2A to 92-2F): Open or Short to Ground in Passenger's Airbag Cutoff Indicator

NOTE: This DTC can be set if the key is turned on when the passenger's airbag cutoff indicator is unplugged.

1. Erase the DTC memory.
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 92-2x 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, go to the Trouble Code Descriptions.

3. Check the connection between the dashboard wire harness A 4P connector and the passenger's airbag cutoff indicator.
4. Erase the DTC memory.
5. Check for a DTC.

Is DTC 92-2x indicated?

YES - Go to step 6.

NO - Repair the poor connections and retest. If DTC 92-2x is still present, go to step 6.

6. Check the No. 7 (7.5 A) fuse in the driver's under-dash fuse/relay box.

Is the fuse OK?

YES - Go to step 7.

NO - Replace the fuse, then turn the ignition switch ON (II). If the fuse blows again, check for a short in the No. 7 (7.5 A) fuse circuit (dashboard wire harness A).

7. Disconnect the passenger's airbag cutoff indicator 4P connector.
8. Turn the ignition switch ON (II).




9. Check for voltage between the No. 1 terminal of the passenger's airbag cutoff indicator 4P connector and body ground. There should be battery voltage.

Is there battery voltage?

YES - Go to step 10.

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

10. Turn the ignition switch OFF. Disconnect the battery negative cable, and wait for 3 minutes.
11. Disconnect SRS unit connector A (28P) from the SRS unit.
12. Reconnect the dashboard wire harness A 4P connector to the passenger's airbag cutoff indicator.

Is the resistance as specified?

YES - Go to step 21.

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




21. Check resistance between the No. 20 terminal of SRS unit connector A (28P) and body ground. There should be an open circuit, or at least 1 MOhms.

Is the resistance as specified?

YES - Check for faulty SRS unit or passenger's airbag cutoff indicator; replace the passenger's airbag cutoff indicator. If the problem is still present, replace the SRS unit.
