DTC 92-2x
DTC 92-2x ("x" can be 0 thru 9 or A thru F): Open or Short to Ground in the Passenger's Airbag Cutoff IndicatorNOTE: Before doing this troubleshooting procedure, review SRS Precautions and Procedures and General Troubleshooting Information.
1. Clear 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. Troubleshooting Intermittent Failures If another DTC is indicated, troubleshoot the DTC.
3. Check the connection between the dashboard wire harness 8P connector and the passenger's airbag cutoff indicator.
4. Clear 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, SRS harness, or ODS unit harness).
7. Disconnect the passenger's airbag cutoff indicator 8P connector (A).
8. Turn the ignition switch ON (II).
9. Measure the for voltage between the No.7 terminal of the passenger's airbag cutoff indicator 8P connector and body ground. There should be battery voltage.
Is there battery voltage?
YES - Go to step 10.
NO - Open in dashboard wire harness A; replace dashboard wire harness A.
10. Turn the ignition switch OFF. Disconnect the negative cable from the battery, and wait for 3 minutes.
11. Disconnect SRS unit connector A (28P) from the SRS unit.
12. Reconnect the dashboard wire harness A 8P connector to the passenger's airbag cutoff indicator.
13. Reconnect the negative cable to the battery.
14. Connect the No.12 terminal of SRS unit connector A (28P) to body ground with a jumper wire.
15. Turn the ignition switch ON (II).
16. Check the passenger's airbag cutoff indicator.
Does the passenger's airbag cutoff indicator come on?
YES - Faulty SRS unit; replace the SRS unit.
NO - Go to step 17.
17. Turn the ignition switch OFF.
18. Disconnect the jumper wire.
19. Disconnect the passenger's airbag cutoff indicator 7P connector again.
20. Measure the resistance between the No.5 terminal of the passenger's airbag cutoff indicator 7P connector and the No.12 terminal of SRS unit connector A (28P). There should be less than 1.0 ohm.
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.
NO - Go to step 21.
21. Disconnect SRS dashboard wire harness A 28P connector C821 (A) from SRS subharness connector C821 (B).
22. Measure the resistance between the No.5 terminal of the passenger's airbag cutoff indicator 7P connector and the No.15 terminal of dashboard wire harness A 28P connector C821. There should be less than 1.0 ohm.
Is the resistance as specified?
YES - Open in the SRS subharness; replace the SRS subharness.
NO - Open in dashboard wire harness A; replace dashboard wire harness A.
