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.

Faulty Power Supply (VB Line)
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. 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.
Faulty SRS unit or poor contact at SRS unit
connector A (28P) and the SRS unit; check the
connection. If the connection is OK, replace the
SRS unit (see page 24-203).
Go to step 6.
