6. Turn the ignition switch OFF.
7. Check the No.9 (7.5 A) fuse in the driver's under- dash fuse/relay box.
Is the fuse OK?
YES - Go to step 8.
NO - Short to ground in the No.9 (7.5 A) fuse circuit; and continue troubleshooting.
8. Check for a blown side airbag indicator bulb. Is the side airbag indicator bulb OK?
YES - Go to step 9.
NO - Blown side airbag indicator bulb; replace the bulb.
9. Disconnect OPDS unit connector D (8P) from the OPDS unit (B).
10. Turn the ignition switch ON (II).
11. Check for voltage between the No.3 terminal of OPDS unit connector D (8P) and body ground. There should be battery voltage.
Is there battery voltage?
YES - Go to step 12.
NO - Go to step 24.
12. Turn the ignition switch OFF.
13. Disconnect dashboard wire harness connector I (18P) from the driver's under-dash fuse/relay box.
14. Turn the ignition switch ON (II).
15. Check for voltage between the No.3 terminal of OPDS unit connector D (BP) and body ground. There should be 0.5 V or less.
Is the voltage as specified?
YES - Faulty OPDS unit; replace the OPDS unit.
NO - Go to step 16.
16. Turn the ignition switch OFF.
17. Disconnect gauge assembly connector B (22P) from the gauge assembly.
18. Turn the ignition switch ON (II).
19. Check for voltage between the No.3 terminal of OPDS unit connector D (8P) 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.
NO - Go to step 20.
20. Turn the ignition switch OFF.
21. Disconnect the right side wire harness 6P connector C582 (A) from the dashboard wire harness A 6P connector (B).
22. Turn the ignition switch ON (II).
23. Check for voltage between the No.3 terminal of OPDS unit connector D (8P) and body ground. There should be 0.5 V or less.
Is the voltage as specified?
YES - Short to power in dashboard wire harness A; replace dashboard wire harness A.
NO - Short to power in the right side wire harness or the OPDS unit harness; if the OPDS unit harness is OK, replace the right side wire harness.
24. Turn the ignition switch OFF.
25. Backprobe the No.17 terminal of gauge assembly connector B (22P). Do not disconnect gauge assembly connector B (22P) from the gauge assembly.
26. Turn the ignition switch ON (II).
27. Check for voltage between the No.17 terminal of gauge assembly connector B (22P) and body ground. There should be battery voltage.
Is there battery voltage?
YES - Go to step 28.
NO - Go to step 32.
28. Turn the ignition switch OFF.
29. Disconnect the right side wire harness 6P connector C582 (A) from the dashboard wire harness A 6P connector (B).
30. Turn the ignition switch ON (II).
31. Check for voltage between the No.5 terminal of the dashboard wire harness A 6P connector (C582) and body ground. There should be battery voltage.
Is there battery voltage?
YES - Poor contact at the dashboard wire harness A 6P connector and right side wire harness 6P connector or an open in the right side wire harness. Check the connection between the dashboard wire harness A 6P connector and right side wire harness 6P connector; if the connection is OK, replace the right side wire harness.
NO - Poor contact at the dashboard wire harness A 22P connector and gauge assembly connector C (22P), or an open in dashboard wire harness A. Check gauge assembly connector B (22P) and gauge assembly connections; if the connections are OK, replace dashboard wire harness A.
32. Turn the ignition switch OFF.
33. Disconnect gauge assembly connector B (22P) from the gauge assembly.
34. Turn the ignition switch ON (II).
35. Check for voltage between the No.11 terminal of gauge assembly connector B (22P) and body ground. There should be battery voltage.
Is there battery voltage?
YES - Faulty side airbag indicator light circuit; replace the gauge assembly.
NO - Open in dashboard wire harness A; replace dashboard wire harness A.
36. Turn the ignition switch OFF.
37. Disconnect OPDS unit connector D (8P) from the OPDS unit (B).
38. Turn the ignition switch ON (II).
Does the side airbag indicator light stay off?
YES - Go to step 39.
NO - Faulty OPDS unit; replace the OPDS unit.
39. Turn the ignition switch OFF.
40. Disconnect gauge assembly connector B (22P) from the gauge assembly.
41. Check resistance between the No. 17 terminal of gauge assembly connector B (22 P) and body ground. There should 1 M Ohm or more.
Is the resistance as specified?
YES - Short to ground in the side airbag indicator light circuit; replace the gauge assembly.
NO - Short to ground in dashboard wire harness A, right side wire harness, or OPDS unit harness; replace the faulty harness.
