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.

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.
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).

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
connection between the connector and the SRS
unit. If the connection is OK, replace the SRS unit
(see page 24-203).
Go to step 11.
11. Turn the ignition switch to LOCK (0).
12. Disconnect under-dash fuse/relay box connector J
(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.
Open in the dashboard wire harness; replace
the dashboard wire harness, then clear the DTC.
