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.

Symptom Troubleshooting (cont’d)
SRS UNIT CONNECTOR A (28P)
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. Connect the HDS to the data link connector (DLC) (see page 24-22).
2. Turn the ignition switch to ON (II).
3. Make sure the HDS communicates with the vehicle and the SRS unit. If it does not communicate,
troubleshoot the DLC circuit (see page 11- 204).
4. Select Body Electrical status with the HDS.
5. Check for DTCs in the Gauge Menu with the HDS.
Go to the troubleshooting for DTC B 1187
(see page 22-265).
Go to step 6.
6. Check that the HDS communicates with the SRS unit.
Go to step 7.
If the HDS does not communicate with the
SRS unit, check for power and ground at the SRS
unit connector A (28P). If power and grounds are ok,
replace the SRS unit (see page 24-203).
7. From the HDS System Menu, select SRS, then SRS in Mode Menu, PARAMETER INFORMATION, then
SCS, MES, Indicator. Read the current status of the
SRS indicator.
Faulty SRS unit; replace the SRS unit
(see page 24-203).
Go to step 8. 8. Do the gauge self-diagnostic test (see page 22-241).
Go to step 9.
Faulty gauge control module (tach); replace
the gauge control module (tach) (see page 22-277).
9. Turn the ignition switch to LOCK (0). Disconnect the negative cable from the battery, and wait at least 3
minutes.
10. Disconnect the SRS unit connector A (28P) from the SRS unit (see step 8 on page 24-21).
11. Measure the resistance between SRS unit connector A (28P) terminal No. 5 and body ground.
There should be an open circuit or at least 1 M .
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).
Short in the dashboard wire harness; replace
the dashboard wire harness.

Deployment tool 07HAZ-SG00500
Before scrapping any airbags, side airbags, side curtain
airbags, seat belt tensioners, or seat belt buckle
tensioner (including those in a whole vehicle to be
scrapped), the part(s) must be deployed. If the vehicle is
still within the warranty period, the Honda District Parts
and Service Manager must give approval and/or special
instructions before deploying the part(s). Only after the
part(s) have been deployed (as the result of vehicle
collision, for example), can they be scrapped.
If the parts appear intact (not deployed), treat them with
extreme caution. Follow this procedure.
If an SRS equipped vehicle is to be entirely scrapped, its
airbags, side airbags, side curtain airbags, seat belt
tensioners, and seat belt buckle tensioner should be
deployed while still in the vehicle. These parts should
not be considered as salvageable parts and should
never be installed in another vehicle.1. Turn the ignition switch to LOCK (0), then disconnect the negative cable from the battery,
then wait at least 3 minutes before starting work.
2. Confirm that each airbag, side airbag, side curtain airbag, seat belt tensioner, or seat belt buckle
tensioner is securely mounted.
3. Confirm that the deployment tool is functioning properly by following the check procedure on the
tool label.
4. Remove the access panel (A) from the steering wheel, then disconnect the driver’s airbag 4P
connector (B) from the cable reel. 5. Remove the glove box, then disconnect the front
passenger’s airbag 4P connector (A) from the
dashboard wire harness.
6. Disconnect the side airbag 2P connector (A) from the floor wire harness.
7. Disconnect the floor wire harness 2P connector from the side curtain airbag (A).

Deploying Components Out of the Vehicle
24-198SRS
Airbag and Tensioner Disposal (cont’d)
A
11. Connect a 12 V battery to the tool.
 If the green light on the tool comes on, the ignitercircuit is defective and cannot deploy the
component. Go to Disposal of Damaged
Components.
 If the red light on the tool comes on, the component is ready to be deployed.
12. Push the tool’s deployment switch. The airbags and tensioners should deploy (deployment is both
highly audible and visible: A loud noise and rapid
inflation of the bag, followed by slow deflation).
 If the components deploy and the green light on the tool comes on, continue with this procedure.
 If a component does not deploy, and the green light comes ON, its igniter is defective. Go to
Disposal of Damaged Components.
 During deployment, the airbags can become hot enough to burn you. Wait for 30 minutes after
deployment before touching the airbags.
13. Dispose of the complete airbag. No part of it can be reused. Place it in a sturdy plastic bag (A), and seal
it securely. Dispose of the deployed airbag
according to your local regulations. If an intact airbag or tensioner has been removed from
a scrapped vehicle, or has been found defective or
damaged during transit, storage, or service, it should be
deployed as follows:
1. Confirm that the deployment tool is functioning properly by following the check procedure
Deploying Airbags in the Vehicle on the tool label.
2. Position the airbag face up, outdoors, on flat ground, at least 30 ft (10 m) from any obstacles or
people.
3. Follow steps 10 through 13 of the in-vehicle deployment procedure.
NOTE: The driver’s and front passenger’s airbags
have dual inflators. Twist each pair of unlike
colored wires together, and clip an alligator clip to
each pair.
