Airbag
Disposal
Before scrapping any airbags (including those in a wholevehicle to be scrapped), the airbags must be deployed. lfthe vehicle is still within the warranty period, before youdeploy the airbags, the Honda District Service Managermust give approval and/or special instructions. Onlv afterthe airbags have been deployed (as the result of vehiclecollision, for example), can they be scrapped.lf the airbags appear intact (not deployed). treat themwith extreme caution.
Follow this p.ocedure:
Deploying the Airbags: In.vehiclo
NOTE: lf an SRS vehicle is to be entirely scrapped, itsairbags should be deployed while still in the vehicle. Theairbags should not be considered as salvageable partsand should never be installed in another veh;cle.
!@ confirm thst oach airbag assembty issecurely mounted; otharwiso. sev€re personal iniurycould result lrom deployment.
1. Disconnect the baftery negative cable, then discon_nect the positive cable.
2. Confirm that the special tool is functioning properlyby following the check procedure on the tool labelor on page 24-'l'l .
Driver's Airbag:
3. Remove the access panel, then disconnect the 2pconnector between the driver,s airbag and the cablereet.

In the "OHMS" range, the DVOM will measure
resistance between two points along a circuit.
Low resistance means good continuity.
Diodes and solid-state devices in a circuit can
make a DVOM give a false reading. To check
a reading, reverse the leads, and take a
second reading. lf the readings differ, the
component is affecting lhe measurement.
Jumper Wire
Use a jumper wire to bypass an open circuit.
A iumper wire is made up ot an in-line fuse
holder connected to a set of test leads. lt
should have a five amoere fuse. Never
connect a jumper wire across a short circuit.
The direct battery short will blow the fuse.
Short Finder (Short Circuit Locater)
Short finders are available to locale shorts to
ground. The short tinder creates a pulsing
magnetic field in the shorted circuit whlch you
can follow to the location of the short. lts use
is explained on page 15.
SHORT FINDER
To ordei any test equipment shown above,
contact your local tool supplier. For a list of
suppliers and tool numbers, refer to Honda
Required Special Tools and Equipment
Service Bulletin.

Troubleshooting Precautions
Before Troubleshooting
1. Check the main fuse and the fuse box.
2. Check the battery for damage, state of
charge, and clean and tight connections.
CAUTION:
. Do not quick-charge a battery unlers
the battery ground cable has been
disconnected, or you will damage the
alternator diodes.
. Do not attempt to crank the engine wlth
the ground cable disconnected or you
will severely damage the wiring.
While You're Working
1. Make sure connectors are clean, and have
no loose terminals or receptacles.
2. Make sure lhat connectors without wire
seals are packed with dielectric (silicone)
grease. Part Number: 08798-9001 .
Pack wllh dlelectrlc (sillcons) greass
When connecting a connector, push it until it"clicks" into place.
Do not pull on the wires when
disconnecting a connector. Pull
only on the connector houslngs.
Most circuits Include solid-state
devlces. Test the voltages In these
circuits only with a lo-megaohm or
higher impedance digital multlm6ter.
Never use a test light or analog meter
on chcuits that contain solld-state
devices. Damage to the devices
may result.
