Is the voltage as specified?
YES - Faulty OPDS unit; replace the OPDS unit.
NO - Go to step 15.
15. Turn the ignition switch OFF.
16. Remove the gauge assembly.Then disconnect gauge assembly connector A from the gauge assembly.
17. Turn the ignition switch ON (II).
18. Check for voltage between the No.3 terminal of OPDS unit harness 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 19.
19. Turn the ignition switch OFF.
20. Disconnect the floor wire harness 6P connector C563 (A) from the dashboard wire harness A.
21. Turn the ignition switch ON (II).
22. Check for voltage between the No.3 terminal of OPDS unit harness 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 floor wire harness or in the OPDS unit harness; if the OPDS unit harness is OK, replace the floor wire harness.
23. Turn the ignition switch OFF.
24. Backprobe the No.21 terminal of gauge assembly connector A (22P). Do not disconnect gauge assembly connector A (22P) from the gauge assembly.
25. Turn the ignition switch ON (II).
26. Gauge assembly with four meters: Check for voltage between the No.21 terminal of gauge assembly connector A (22P) and body ground. There should be battery voltage.
Gauge assembly with three meters: Check for voltage between the No.8 terminal of gauge assembly connector A (22P) and body ground. There should be battery voltage.
Is there battery voltage?
YES - Go to step 28.
NO - Go to step 32.
27. Turn the ignition switch OFF.
28. Disconnect the floor wire harness 6P connector C563 (A) from the dashboard wire harness A.
28. Disconnect the floor wire harness 6P connector C563 (A) from the dashboard wire harness A
29. Turn the ignition switch ON (II).
30. Check for voltage between the No.4 terminal of the dashboard wire harness A 6P connector (C563) and body ground. There should be battery voltage.
Is there battery voltage?
YES - Poor contact at the dashboard wire harness A 6P and floor wire harness 6P connectors or an open in floor wire harness or in the OPDS unit harness. Check connector C555 and the connection between the dashboard wire harness A 6P and floor wire harness 6P connectors; if the connector and connection are OK, replace the faulty harness.
NO - Poor contact at gauge assembly connector A (22P) or an open in dashboard wire harness A. Check the connections at gauge assembly connector A (22P); if the connections are OK, replace dashboard wire harness A.
31. Turn the ignition switch OFF.
32. Remove the gauge assembly.Then disconnect gauge assembly connector A (22P) from the gauge assembly.
33. Turn the ignition switch ON (II).
34. Gauge assembly with four meters: Check for voltage between the No.17 terminal of gauge assembly connector A (22P) and body ground. There should be battery voltage.
Gauge assembly with three meters: Check for voltage between the No.15 terminal of gauge assembly connector A (22P) and body ground. There should be battery voltage.
Is there battery voltage?
YES - Faulty side airbag cutoff indicator circuit; replace the gauge assembly.
NO - Open in dashboard wire harness A; replace dashboard wire harness A.
35. Turn the ignition switch OFF.
36. Disconnect OPDS unit harness connector D (8P) from the OPDS unit (B).
37. Turn the ignition switch ON (II).
Does the side airbag cutoff indicator come on?
YES - Go to step 38.
NO - Faulty OPDS unit; replace the OPDS unit.
38. Turn the ignition switch OFF.
