## DTC Troubleshooting: 15-2

DTC 15-2: | Faulty Side Airbag Cutoff Indicator Circuit

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? YES - Go to 3. NO - Intermittent failure, system is OK at this time. Go to Troubleshooting Intermittent Failures.

3. | Turn the ignition switch OFF. Make sure nothing is on the front passenger's seat.

4. | Turn the ignition switch ON (II), and check that the side airbag cutoff indicator comes on. Does the side airbag cutoff indicator come on? YES - Go to 5. NO - Go to 6.

5. | Make sure the side airbag cutoff indicator comes on for 5 seconds and then goes off. Does the side airbag cutoff indicator go off? YES - Faulty OPDS unit or SRS unit; replace the OPDS unit. If the problem is still present, replace the SRS unit.n NO - Go to 35.

6. | Turn the ignition switch OFF.

7. | Check the No. 15 (10A) fuse in the under-dash fuse/relay box. Is the fuse OK? YES - Go to 8. NO - Repair the short to ground in the No. 15 (10A) fuse circuit.n

8. | Disconnect the O1o connector (A) from the OPDS unit (B).

9. | Turn the ignition switch ON (II).

10. | Check for voltage between the No. 3 terminal of the O1o connector and body ground. There should be battery voltage. Is there battery voltage? YES - Go to 11. NO - Go to 23.

11. | Turn the ignition switch OFF.

12. | Disconnect the F3o connector (A) from the under-dash fuse/relay box (B).

13. | Turn the ignition switch ON (II).

14. | Check for voltage between the No. 3 terminal of the O1o connector and body ground. There should be 0.5 V or less. Is the voltage as specified? YES - Faulty OPDS unit; replace the OPDS unit.n NO - Go to 15.

15. | Turn the ignition switch OFF.

16. | Disconnect C1 connector (A) from the gauge assembly.

17. | Turn the ignition switch ON (II).

18. | Check for voltage between the No. 3 terminal of the O1o connector and body ground. There should be 0.5 V or less. Is the voltage as specified? YES - Short to power in the gauge assembly; replace the gauge assembly.n NO - Go to 19.

19. | Turn the ignition switch OFF.

20. | Disconnect the C4 connector (A) from the C3 connector (B).

21. | Turn the ignition switch ON (II).

22. | Check for voltage between the No. 3 terminal of the O1o connector and body ground. There should be 0.5 V or less. Is the voltage as specified? YES - Short to power in the dashboard wire harness; replace the dashboard wire harness.n NO - Short to power in the floor wire harness or in the OPDS unit harness; if the OPDS unit harness is OK, replace the floor wire harness.n

23. | Turn the ignition switch OFF.

24. | Backprobe the No. 25 terminal of C1 connector. Do not disconnect C1 connector from the gauge assembly.

25. | Turn the ignition switch ON (II).

26. | Check for voltage between the No. 25 terminal of C1 connector and body ground. There should be battery voltage. Is there battery voltage? YES - Go to 27. NO - Go to 31.

27. | Turn the ignition switch OFF.

28. | Disconnect the C4 connector (A) from the C3 connector (B).

29. | Turn the ignition switch ON (II).

30. | Check for voltage between the No. 3 terminal of the C3 connector and body ground. There should be battery voltage. Is there battery voltage? YES - Poor contact at the C4 and C3 connectors or an open in floor wire harness or in the OPDS unit harness. Check the connection between the C4 and C3 connectors; if the connection is OK, replace the faulty harness.n NO - Poor contact at gauge assembly connector B (18P) or an open in the dashboard wire harness. Check C2 connector; if the connections are OK, replace the dashboard wire harness.n

31. | Turn the ignition switch OFF.

32. | Disconnect C2 connector (A) from the gauge assembly.

33. | Turn the ignition switch ON (II).

34. | Check for voltage between the No. 2 terminal of C2 connector and body ground. There should be battery voltage. Is there battery voltage? YES - Faulty side airbag cutoff indicator circuit; replace the gauge assembly.n NO - Open in the dashboard wire harness; replace the dashboard wire harness.n

35. | Turn the ignition switch OFF.

36. | Disconnect the O1o connector (A) from the OPDS unit (B).

37. | Turn the ignition switch ON (II). Does the side airbag cutoff indicator come on? YES - Go to 38. NO - Faulty OPDS unit; replace the OPDS unit.n

38. | Turn the ignition switch OFF.

39. | Disconnect C1 connector (A) from the gauge assembly.

40. | Check resistance between the No. 25 terminal of C1 connector and body ground. There should 1 MW or more. Is the resistance as specified? YES - Short to ground in the side airbag cutoff indicator circuit; replace the gauge assembly.n NO - Short to ground in the dashboard wire harness A, floor wire harness or OPDS unit harness; replace the faulty harness.n
