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).

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).
