NOTE: Before doing this troubleshooting procedure,
review SRS Precautions and Procedures (see page
24-13), General Troubleshooting Information (see page
24-22), and Battery Terminal Disconnection and
Reconnection (see page 22-68).
1. Make sure nothing is on the front passenger’s seat.
2. Clear the DTC memory (see page 24-23).
3. Read the DTC (see page 24-22).
Go to step 4.
Intermittent failure, system is OK at this time.
Go to Troubleshooting Intermittent Failures
(see page 24-24). If another DTC is indicated,
troubleshoot the DTC.
4. Check the connection between the ODS unit harness 18P connector and the ODS unit.
Go to step 6.
Repair the poor connection, clear the DTC,
and retest. If DTC 85-61 or 85-62 is still present, go
to step 5.
5. Turn the ignition switch to LOCK (0).
6. Check the No. 9 (7.5 A) fuse in the under-dash fuse/ relay box.
Go to step 7.
Replace the fuse, then turn the ignition switch
to ON (II). If the fuse blows again, check for a short
in the No. 9 (7.5 A) fuse circuit (floor wire harness,
front passenger’s seat wire harness (with seat
heater), or ODS unit harness). 7. Disconnect the ODS unit harness 18P connector (A)
from the ODS unit.
8. Turn the ignition switch to ON (II).
9. Measure the voltage between ODS unit harness 18P connector terminal No. 1 and body ground.
There should be battery voltage.
Go to step 10.
Open in the floor wire harness, front
passenger’s seat wire harness (with seat heater) or
ODS unit harness; replace the faulty harness, then
clear the DTC.

10. Turn the ignition switch to LOCK (0).
11. Measure the resistance between ODS unit harness
18P connector terminal No. 12 and body ground.
There should be less than 1.0 .
Go to step 12.
Open in the ODS unit harness, front
passenger’s seat wire harness (with seat heater), or
floor wire harness; replace the faulty harness, then
clear the DTC.
12. Turn the ignition switch to LOCK (0). Disconnect the negative cable from the battery, then wait at least 3
minutes.
13. Disconnect SRS unit connector A (28P) from the SRS unit (see step 9 on page 24-21). 14. Measure the resistance between SRS unit
connector A (28P) terminal No. 14 and body ground.
There should be an open circuit or at least 1 M .
Go to step 15.
Short to ground in the dashboard wire
harness, front passenger’s seat wire harness (with
seat heater), or floor wire harness; replace the
faulty harness, then clear the DTC.
