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.

Handling Wires and Harnesses

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.

Slip pliers under the clip base and through the hole at

an angle, then squeeze the expansion tabs to release the

clip.

SNAP-RING PLIERS

After installing harness clips, make sure the harness

doesn't interfere with any moving parts.

Keep wire harnesses away from exhaust pipes and

other hot parts, from sharp edges of brackets and

holes, and from exposed screws and bolts.
Seat grommets in their grooves properly.

Testing and Repairs

Do not use wires or harnesses with broken insulation.

Replace them or repair them by wrapping the break

with electrical tape.

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 a probe with a tapered tip.

Refer to the instructions in the Honda Terminal Kit for

identification and replacement of connector termi-

Five-step Troubleshooting

1. Verify The Complaint

Turn on all the 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 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 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 proce-

dure 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 proce-

dures.

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 prob-

lem. 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.
Wire Color Codes

The following abbreviations are used to identify wire

colors in the circuit schematics:

WHT .............................White

YEL ............................... Yellow

BLK .............................. Black

BLU

Red

ORN ............................. Orange

PNK.............................. Pink

BRN .............................. Brown

GRY.............................. Gray

PUR .............................. Purple

LT BLU ......................... Light Blue

LT GRN ........................ Light Green

The wire insulation has one color or one color with

another color stripe. The second color is the stripe.

WHT/BLK

NOTE: Different wires with the same color in the same

system have been given number suffixes to distinguish

them (for example, YEL1 and YEL2 are not the same).ProCarManuals.com
