DTC 85-61
DTC 85-61: No Signal from OPDS Unit1. Make sure nothing is on the front passenger's seat.
2. Initialize the OPDS unit.
3. Erase the DTC memory.
4. Check for a DTC.
Is DTC 85-61 or 85-62 indicated?
YES - Go to step 5.
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.
5. Check the connection between the OPDS unit harness 8P connector and the OPDS unit.
Is the connection OK?
YES - Go to step 6.
NO - Repair the poor connection and retest. If DTC 85-61 or 85-62 is still present, go to step 6.
6. Erase the DTC.
7. Check for a DTC.
Is DTC 85-61 or 85-62 indicated?
YES - Go to step 8.
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.
8. Turn the ignition switch OFF.
9. Check the No. 7 (7.5 A) fuse in the driver's under-dash fuse/relay box.
Is the fuse OK?
YES - Go to step 10.
NO - Replace the fuse, then turn the ignition switch ON (II). If the fuse blows again, check for a short in the No. 7 (7.5 A) fuse circuit (dashboard wire harness A, left floor wire harness or OPDS unit harness).
10. Disconnect the OPDS unit harness 8P connector D from the OPDS unit.
11. Turn the ignition switch ON (II).
12. Check for voltage between the No. 4 terminal of the OPDS unit harness 8P connector D and body ground. There should be battery voltage.
Is there battery voltage?
YES - Go to step 17.
NO - Go to step 13.
13. Turn the ignition switch OFF.
14. Disconnect dashboard wire harness A 10P (without power seat: 4P) connector C801 from the SRS floor harness connector C801.
15. Turn the ignition switch ON (II).
16. Check for voltage between the No. 1 terminal of dashboard wire harness A 10P (without power seat: 4P) connector C801 and body ground. There should be battery voltage.
Is there battery voltage?
YES - Open in the YEL/GRN wire of the SRS floor harness or OPDS unit harness; replace the faulty harness.
NO - Open in the YEL/GRN wire of dashboard wire harness A; replace dashboard wire harness A.
17. Turn the ignition switch OFF.
18. Check resistance between the No. 8 terminal of the OPDS unit harness 8P connector D and body ground. There should be 0 - 1.0 Ohm.
Is the resistance as specified?
YES - Go to step 19.
NO - Open in the BLK wire of the SRS floor harness, or OPDS unit harness or poor ground at G801. Check the connection at G801; if necessary, replace the faulty harness.
19. Disconnect the battery negative cable, and wait for 3 minutes.
20. Disconnect both seat belt tensioner 2P connectors.
21. Disconnect SRS unit connector B (28P) from the SRS unit.
22. Check resistance between the No. 27 terminal of SRS unit connector B (28P) and body ground. There should be an open circuit or at least 1 MOhms.
Is the resistance as specified?
YES - Go to step 23.
NO - Short to ground in the right side wire harness, SRS floor harness, or OPDS unit harness; replace the faulty harness.
23. Check resistance between the No. 27 terminal of SRS unit connector B (28P) and the No. 7 terminal of the OPDS unit harness 8P connector D. There should be 0 - 1.0 Ohm.
Is the resistance as specified?
YES - Faulty OPDS unit or SRS unit; replace the OPDS unit. If the problem is still present, replace the SRS unit.
NO - Open in the right side wire harness, SRS floor harness, or OPDS unit harness; replace faulty harness.
