Troubleshooting
Tips and Precautions
Never try to disconnect connectors by pulling on their
wires; pull on lhe connector halves instead.
Alwavs reinstall Dlastic covers.
Before connecting connectors, make sure the termi-
nals are in Dlace and not bent.
a Check lor loose retainer and rubber seals.
The backs of some connectors are packed with
grease. Add grease if needed. lf the grease is contami-
nated, reolace it.

Bef ore Troubleshooting
a Check applicable tuses in the appropriate fuse/relay
box.
Check the battery for damage, state of charge, and
clean and tight connections.
Check the alternator belt tension.
CAUTION:
a Do not quick-charge a battely unless the battery
ground cable has been disconnected. otherwise
you will damage the alternator diod€s.
a Do not attempt to crank the engine with the bat-
tery ground cable loosely connected or you willse-
verely damage the wiring.
a The originsl radio has a coded theft plotection cir-
cuit. Be sure to get the customel's code numbel
before- disconnecting the battsry.- removing the No. 47 (7.5 A) fuse from tho
under-hood luse/relay box.- removing the radio.
Atter service. leconnect Dower to the radio and
tum it on. When the word "CODE" is displayed,
enter the customer's 5-digit code to restore radio
ooeration.
Handling Connectors
a Make sure the connectors are clean and have no loose
wire terminals.
a Make sure multiple cavity connectors are packed with
grease (except watertight connectors).
a All connectors have push-down release type locks.
LOCKING TAB
LOCKING TAB
Some connectors have a clip on their side used to at-
tach them to a mount bracket on the body or on
another component. This clip has a pull type lock.
Some mounted connectors cannot be disconnected
unless you tirst release the lock and remove the con-
nector from its bracket.

Troubleshooting
Tips and Precautions (cont'd)
Insert the connector all the way and make sure it is
securely locked.
Position wires so that the open end of the cover faces
down.Faceopen end

Handling Wires and Harnesses
I Secure wires and wire harnesses to the frame with
their respective wire ties at the designated locations.
a Remove clips carefully; don't damage their locks.
Slip pliers under the clip base and through the hole at an
angle, then squeez€ the expansion tabs to release the
clro.
sNAP-R|NG PLtERS
After installing harness clips, make sure the harness
doesn't interlere with any moving parts.
Keep wire harnesses away from exhaust pipes and
other hot parts, trom sharp edges ol brackets and
holes, and from exposed screws and bolts.

Testing and Repairs
a Do not use wires or harnesses with broken insulation.
Replace them or repair them by wrapping the break
with electrical tape.
a Atter installing parts. make sure that no wires are
oinched under them.
a When using electrical test equipment. follow the
manulacturer's instructions and those described in
this manual.
a lI possible, insert the probe of the tester {rom the wire
side {except waterproot connector).
a Seat grommets in their grooves properly.
a Use a probe with a tapered tip.
Reler to the instructions in the Honda Terminal Kit for
identification and replacement oI connector terminals.

I . Verify The Complaint
Turn on allthe components in the problem circuit to
verify the customer complaint. Note the symptoms.
Do not begin disassembly or testing until you have
narrowed down the problem area.
2- Analyze The Schomatic
Look up the schematic for the problem circuit. De-
termine how the circuit is supposed to work by trac-
ing the current paths from the power feed through
the circuit components to ground. lf several circuits
fail at the same time, the fuse or ground is a likely
Based on the symptoms and your understanding ot
the circuit operation, identity one or more possible
causes of the problem.
3. lsolata The Problem By Testing The Circuit
Make circuit tests to check the diagnosis you made
in step 2. Keep in mind that a logical, simple proce-
dure is the key to efficient troubleshooting. Test for
the most likely cause of failure lirst. Try to make
tests at points that are easilV accessible.
4. Fix The Problem
Once the specific problem is identified, make therepair. Be sure to use proper tools and safep.ocedures.
5. Make Sure The Circuit Workg
Turn on all components in the repaired circuit in allmodes to make sure you've fixed the entire problem.
lf the problem was a blown fuse, be sure to test all
of the circuits on that fuse. Make sure no newproblems turn up and the original problem does not
recuf.
