DTC 85-62
DTC 85-62: Non-stipulated Response DataNOTE:
- An incorrect OPDS unit can cause DTC 85-63.
- A new (uninitialized) OPDS unit installed with a faulty sensor can also cause DTC 85-71.
1. Make sure nothing is on the front passenger's seat.
2. Erase the DTC memory.
3. Read the DTC.
Is DTC 85-61 or 85-62 indicated?
YES - Go to step 4.
NO - Intermittent failure, system is OK at this time. Go to Troubleshooting Intermittent Failures. If another DTC is indicated, go to the DTC Troubleshooting Index.
4. Check the connection between the OPDS unit harness 8P connector D and the OPDS unit.
Is the connection OK?
YES - Go to step 5.
NO - Repair the poor connection and retest. If DTC 85-61 or 85-62 is still present, go to step 5.
5. Turn the ignition switch OFF.
6. Check the No. 10 (7.5 A) fuse in the under-dash fuse/relay box.
Is the fuse OK?
YES - Go to step 7.
NO - Replace the fuse, then turn the ignition switch ON (II). If the fuse blows again, check for a short in the No. 10 (7.5 A) fuse circuit (dashboard wire harness, floor wire harness, or OPDS unit harness).
7. Disconnect the OPDS unit 8P connector D from the OPDS unit.
8. Turn the ignition switch ON (II).
9. Check for voltage between the No. 4 terminal of the OPDS unit 8P connector D and body ground. There should battery voltage.
Is there battery voltage?
YES - Go to step 14.
NO - Go to step 10.
10. Turn the ignition switch OFF.
11. Disconnect dashboard wire harness 21 P connector C551 (A) from the right floor wire harness C551 (B).
12. Turn the ignition switch ON (II).
13. Check for voltage between the No. 20 terminal of dashboard wire harness 21P connector C551 and body ground. There should be battery voltage.
Is there battery voltage?
YES - Open in the WHT wire of the right floor wire harness or OPDS unit harness; replace the faulty harness.
NO - Open in the WHT wire of the dashboard wire harness; replace the dashboard wire harness.
14. Turn the ignition switch OFF.
15. Check resistance between the No. 8 terminal of the OPDS unit 8P connector D and body ground. There should be 0 - 1.0 Ohm.
Is the resistance as specified?
YES - Go to step 16.
NO - Open in the OPDS unit harness or right floor wire harness; check the connection at G651. If the connection is OK, replace the faulty harness.
16. Disconnect the battery negative cable, and wait for 3 minutes.
17. Disconnect both seat belt tensioner4P connectors.
18. Disconnect SRS unit connector B (28P) from the SRS unit.
19. 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 M Ohm.
Is the resistance as specified?
YES - Go to step 20.
NO - Go to step 23.
20. Check resistance between the No. 27 terminal of SRS unit connector B (28P) and the No. 7 terminal of the OPDS unit 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 OPDS sensor/seat-back. If the problem is still present, replace the SRS unit.
NO - Go to step 21.
21. Disconnect the right floor wire harness 4P connector C801 from the OPDS unit harness.
22. Check resistance between the No. 27 terminal of SRS unit connector B (28P) and the No. 4 terminal of right floor wire harness 4P connector C801. There should be 0 - 1.0 Ohm.
Is the resistance as specified?
YES - Open in the OPDS unit harness; replace the OPDS unit harness.
NO - Open in the GRN/ORN wire of the dashboard wire harness or right floor wire harness; replace the faulty harness.
23. Disconnect right floor wire harness 4P connector C801 from the OPDS unit harness.
24. 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 M Ohm.
Is the resistance as specified?
YES - Short to ground in the OPDS unit harness; replace the OPDS unit harness.
NO - Short to ground in the dashboard wire harness or right floor wire harness; replace the faulty harness.
