I have air bag codes 42-11 and 92-20 where do I start. Pilot has not been in any accidents and the codes come back as soon as I clear them. Also checked Battery and it is good.
Thanks

The 42-11 is no signal from the right front impact sensor
The 92-20 is Open or Short to Ground in Passenger's Airbag Cutoff Indicator

Has any work been done to the car recently? Look around and see if anything has been disconnected in the engine compartment or behind the dash.

yes i know what the codes are for, and i inspected all the connections under the seat and at the right front impact sensor and it all looks good. no recent work has been done. There is also a code for the right front abs sensor but i'm assuming that's unrelated.

DTC 42-1x (42-10 to 42-19, 42-1A to 42-1F): No Signal from Right Front Impact Sensor

Special Tools Required
- SRS inflator simulator 07SAZ-TB4011A
- SRS simulator lead H 07YAZ-S3AA100

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 42-1x 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, go to the Trouble Code Descriptions.

3. Turn the ignition switch OFF. Check the connections between SRS unit connector A (28P) and the SRS unit, between the right engine compartment wire harness 2P connector and the right front impact sensor, and at connectors.

Are the connections OK?

YES - Go to step 4.

NO - Repair the poor connections and retest. If DTC 42-1x is still present, go to step 4.

4. Turn the ignition switch OFF. Disconnect the battery negative cable, and wait for 3 minutes.
5. Disconnect the driver's airbag 4P connector (A) from the cable ree.
6. Disconnect the front passenger's airbag 4P connector from the dashboard wire harness A.
7. Disconnect both seat belt tensioner 2P connectors.




8. Disconnect the right front impact sensor 2P connector (A).
9. Disconnect SRS unit connector A (28P) from the SRS unit.




10. Check resistance between the No. 16 and No. 28 terminals of SRS unit connector A (28P). Then check resistance between the No. 16 terminal and body ground and the No. 28 terminal and body ground. There should be an open circuit or at least 1 MOhms.

Is the resistance as specified?

YES - Go to step 11.

NO - Go to step 17.

11. Reconnect the battery negative cable.
12. Turn the ignition switch ON (II).




13. Check for voltage between the No. 28 terminal of SRS unit connector A (28P) and body ground, and the 16 terminal and body ground. There should be 1 V or less.

Is the voltage as specified?

YES - Go to step 14.

NO - Go to step 19.

14. Turn the ignition switch OFF.




15. Connect the SRS inflator simulator (jumper connector) and the simulator lead H to the right engine compartment wire harness 2P connector (A).




16. Check resistance between the No. 16 and No. 28 terminals of SRS unit connector A (28P). There should be 1 Ohm or less.

Is the resistance as specified?

YES - Faulty right front impact sensor. Replace the right front impact sensor, if the problem is still present, replace the SRS unit.

NO - Go to step 23.

17. Disconnect the dashboard wire harness A 2P connector from right engine compartment wire harness 2P connector.




18. Check resistance between the No. 16 and No. 28 terminals of SRS unit connector A (28P). Then check resistance between the No. 16 terminal and body ground and between the No. 28 terminal and body ground. There should be an open circuit or at least 1 MOhms.

Is the resistance as specified?

YES - Short in or to ground the right engine compartment wire harness; replace the right engine compartment wire harness.

NO - Short in or to ground the dashboard wire harness A; replace the dashboard wire harness A.

19. Turn the ignition switch OFF.
20. Disconnect the dashboard wire harness A 2P connector from right engine compartment wire harness 2P connector.
21. Turn the ignition switch ON (II).




22. Check voltage between the No. 28 terminal of SRS unit connector A (28P) and body ground. There should be 1 V or less.

Is the voltage as specified?

YES - Short to power in the right engine compartment wire harness; replace the right engine compartment wire harness.

NO - Short to power in the dashboard wire harness A; replace the dashboard wire harness A.

23. Disconnect the dashboard wire harness A 2P connector from right engine compartment wire harness 2P connector.




24. Check resistance between the No. 1 and No. 2 terminals of right engine compartment wire harness 2P connector. There should be 1 Ohm or less.

Is the resistance as specified?

YES - Faulty dashboard wire harness A; replace the dashboard wire harness A.

NO - Faulty right engine compartment wire harness; replace the right engine compartment wire harness.
