Tips and Precautions

Before Troubleshooting

Handling Connectors

22-3

General Troubleshooting Information

1. Check applicable fuses in the appropriate fuse/relay

box.

2. Check the battery for damage, state of charge, and

clean and tight connections.

• Do not quick-charge a battery unless the

battery ground cable has been
disconnected, otherwise you will damage
the alternator diodes.

• Do not attempt to crank the engine with

the battery ground cable loosely
connected or you will severely damage the
wiring.

• Make sure the connectors are clean and have no

loose wire terminals.

• Make sure multiple cavity connectors are packed with

dielectric grease (except watertight connectors).

• All connectors have push-down release type locks (A).

• Some connectors have a clip on their side used to

attach 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 first release the lock and remove the
connector from its mount bracket (A).

• Never try to disconnect connectors by pulling on their

wires; pull on the connector halves instead.

• Always reinstall plastic covers.

• Before connecting connectors, make sure the

terminals (A) are in place and not bent.

Handling Wires and Harnesses

22-4

Body Electrical

(P/N 08798-9001)

DOWN

• Check for loose retainers (A) and rubber seals (B).

• The backs of some connectors are packed with

dielectric grease. Add grease if necessary. If the
grease is contaminated, replace it.

• 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.

• Secure wires and wire harnesses to the frame with

their respective wire ties at the designated locations.

• Remove clips carefully; don’t damage their locks (A).

• After installing harness clips, make sure the harness

doesn’t interfere with any moving parts.

• Keep wire harnesses away from exhaust components

and other hot parts, from sharp edges of brackets and
holes, and from exposed screws and bolts.

• Seat grommets in their grooves properly (A). Do not

leave grommets distorted (B).

Testing and Repairs

Five-step Troubleshooting

22-5

• Do not use wires or harnesses with broken insulation.

Replace them or repair them by wrapping the break
with electrical tape.

• Never attempt to modify, splice, or repair SRS wiring.

If there is an open or damage is SRS wiring or
terminals, replace the harness.

• After installing parts, make sure that no wires are

pinched under them.

• When using electrical test equipment, follow the

manufacturer’s instructions and those described in
this manual.

• If possible, insert the probe of the tester from the wire

side (except waterproof connector).

• Use back probe adaptor 07TAZ-001020A.

• Refer to the instructions in the Honda Terminal Kit for

identification and replacement of connector terminals.

1. Verify The Complaint:

Turn on all the components in the problem circuit
to verify the client complaint. Note the symptoms.
Do not begin disassembly or testing until you have
narrowed down the problem area.

2. Analyze The Schematic:

Look up the schematic for the problem circuit.
Determine how the circuit is supposed to work by
tracing the current paths from the power feed
through the circuit components to ground. If
several circuits fail at the same time, the fuse or a
ground is a likely cause.

Based on the symptoms and your understanding of
the circuit operation, identify one or more possible
causes of the problem.

3. Isolate 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
procedure is the key to efficient troubleshooting.
Test for the most likely cause of failure first. Try to
make tests at points that are easily accessible.

4. Fix The Problem:

Once the specific problem is identified, make the
repair. Be sure to use proper tools and safe
procedures.

5. Make Sure The Circuit Works:

Turn on all components in the repaired circuit in all
modes to make sure you’ve fixed the entire
problem. If the problem was a blown fuse, be sure
to test all of the circuits on the fuse. Make sure no
new problems turn up and the original problem
does not recur.

The wire insulation has one color or one color with
another color stripe. The second color is the stripe.

NOTE: For specific operations, refer to the user’s
manual that came with the Honda Diagnostic System
(HDS).

1. Connect the HDS to the data link connector (A)

located under the driver’s side of the dashboard.

2. Turn the ignition switch to ON (II).

3. Make sure the HDS communicates with the vehicle,

if it doesn’t, do the DLC circuit troubleshooting
(see page 11-204).

4. Enter the BODY ELECTRICAL, then select the TEST

MODE menu.

5. Check for DTCs with the HDS.

6. If any DTCs are indicated, note them, and go to the

indicated DTC troubleshooting.
