3. Check the connection at the OPDS sensor harness

connectors (A) and the ODS unit harness 18P
connector (B).

Go to step 4.

Repair the poor connection, then clear the

DTC.

4. Replace the OPDS sensor/seat-back foam (see page

20-123), and initialize the ODS unit (see page 24-26),
then clear the DTC.

5. Clear the DTC memory, then check for DTC 86-1x or

86-2x.

Replace the ODS unit (see page 24-209), then

clear the DTC.

The system is OK.

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 check that

the SRS indicator comes on for about 6 seconds
and then goes off.

Go to step 3.

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.

3. Turn the ignition switch to LOCK (0). Disconnect the

negative cable from the battery, then wait at least
3 minutes.

SRS unit (see step 9 on page 24-21).

6. Reconnect the negative cable to the battery.

7. Turn the ignition switch to ON (II).

8. Measure the voltage between SRS unit connector A

(28P) terminal No. 13 and body ground. There
should be less than 0.2 V.

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 power in the dashboard wire

harness; replace the dashboard wire harness, then
clear the DTC.

1. Clear the DTC memory (see page 24-23).

2. Turn the ignition switch to ON (II), and check that

the SRS indicator comes on for about 6 seconds
and then goes off.

6. Measure the resistance between SRS unit

connector A (28P) terminal No. 13 and passenger’s
airbag cutoff indicator 4P connector terminal No. 4.
There should be less than 1.0

Go to step 7.

Open in the dashboard wire harness; replace

the dashboard wire harness, then clear the DTC.

7. Measure the resistance between SRS unit

connector A (28P) terminal No. 13 body ground.
There should be an open circuit or at least 1 M

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.

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,

10. Connect a voltmeter between SRS unit connector A

(28P) terminal No. 17 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 (II).

Faulty SRS unit or poor connection at SRS

unit connector (A) 28P and the SRS unit. Check the

(4P).

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

poor contact between connector J (4P) and the
under-dash fuse/relay box; check the connection. If
the connection is OK, replace the under-dash fuse/
relay box (see page 22-66), then clear the DTC.
