6. Read the DTC.

Is DTC 26-12 indicated?

YES - Go to step 7.

NO - Faulty front passenger's weight sensor (rear outer side); replace the front passenger's weight sensor.

7. Turn the ignition switch OFF.




8. Disconnect the ODS unit harness 18P connector D from the ODS unit.




9. Check resistance between the No. 6 terminal of the ODS unit harness 18P connector D and body ground. There should be an open circuit or at least 1 MOhm.

Is the resistance as specified ?

YES - Go to step 10.

NO - Short to ground in the ODS unit harness; replace the ODS unit harness.




10. Check resistance between the No. 6 terminal and No. 16 terminal of the ODS unit harness 18P connector D. There should be an open circuit or at least 1 MOhm.

Is the resistance as specified?

YES - Faulty ODS unit; replace the ODS unit.

NO - Short to ground in the ODS unit harness; replace the ODS unit harness.

11. Turn the ignition switch OFF.
12. Swap the connections between the front passenger's weight sensor (rear outer side) and the front passenger's weight sensor (front outer side).
13. Read the DTC.

Is DTC 26-13 indicated?

YES - Go to step 14.

NO - Faulty front passenger's weight sensor (rear outer side); replace the front passenger's weight sensor.

14. Turn the ignition switch OFF.




15. Disconnect the front passenger's weight sensor (rear outer side) connector (A) and front passenger's weight sensor (front outer side) connector (B).




16. Disconnect the ODS unit harness 18P connector D from the ODS unit.
17. Turn the ignition switch ON (II).




18. Check for voltage between the No. 11 terminal of the ODS unit harness 18P connector D and body ground. There should be 1 V or less.

Is the voltage as specified?

YES - Faulty ODS unit; replace the ODS unit.

NO - Short to power in the ODS unit harness; replace the ODS unit harness.

19. Turn the ignition switch OFF.




20. Disconnect the ODS unit harness 3P connector (A) from the front passenger's weight sensor (rear outer side).
21. Read the DTC.

Is DTC 26-14 indicated?

YES - Go to step 22.

NO - Faulty front passenger's weight sensor (rear outer side); replace the front passenger's weight sensor.

22. Turn the ignition switch OFF.




23. Disconnect the ODS unit harness 18P connector D from the ODS unit.




24. Check resistance between the No. 11 terminal of the ODS unit harness 18P connector D and body ground. There should be an open circuit or at least 1 MOhm.

Is the resistance as specified?

YES - Go to step 25.

NO - Short to ground in the ODS unit harness; replace the ODS unit harness.




25. Check resistance between the No. 11 terminal and No. 16 terminal of the ODS unit harness 18P connector D. There should be an open circuit or at least 1 MOhm.

Is the resistance as specified?

YES - Faulty ODS unit; replace the ODS unit.

NO - Short in the ODS unit harness; replace the ODS unit harness.
