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.

Check for a faulty SRS unit or passenger’s
airbag cutoff indicator; replace the passenger’s
airbag cutoff indicator (see page 24-212), then clear
the DTC. If the problem is still present, replace the
SRS unit (see page 24-203).
Short to ground in the dashboard wire
harness; replace the dashboard wire harness, then
clear the DTC. 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. Clear the DTC memory (see page 24-23).
2. Turn the ignition switch to ON (II), and wait for 10 seconds.
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. Turn the ignition switch to LOCK (0).
5. Check the No. 9 (7.5 A) fuse in the under-dash fuse/ relay box.
Go to step 6.
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 (dashboard wire
harness, floor wire harness, front passenger’s seat
wire harness (with seat heater), or ODS unit
harness), then clear the DTC.
6. Disconnect the negative cable from the battery, then wait at least 3 minutes.
7. Disconnect the SRS unit connector A (28P) from the SRS unit (see step 9 on page 24-21).
8. Reconnect the negative cable to the battery.
9. Turn the ignition switch to ON (II).

13. Measure the resistance between SRS unit connector A (28P) terminal No. 17 and under-dash
fuse/relay box connector J (4P) terminal No. 4.
There should be less than 1.0 .
Open in the under-dash fuse/relay box or

24-22), and Battery Terminal Disconnection and
Reconnection (see page 22-68).1. Check the No. 11 (10 A) fuse in the under-dash fuse/relay box.
Go to step 2.
Replace the fuse, then turn the ignition switch
ON (II). If the fuse blows again, check for a short to
ground in the under-dash fuse/relay box No. 11
(10 A) fuse line, in the dashboard wire harness;
replace the under-dash fuse/relay box (see page
22-66), then clear the DTC.
2. Turn the ignition switch to LOCK (0). Disconnect the negative cable from the battery, then wait at least 3
minutes.
3. Disconnect SRS unit connector A (28P) from the SRS unit (see step 9 on page 24-21).
4. Reconnect the negative cable to the battery. 5. Connect a voltmeter between SRS unit connector A
(28P) terminal No. 18 and body ground. Turn the
ignition switch to ON (II), and measure the voltage.
There should be battery voltage when the ignition
switch is on.
