Acura RL (1996-2004 year). Manual — part 610
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.
EXPANSION
CLIP 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.
• Refer to the instructions in the Honda Terminal Kit for
identification and replacement of connector
terminals.
• Use a probe with a tapered tip.
• Seat grommets in their grooves properly.
NOT GOOD
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).

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
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.
Wire Color Codes
The following abbreviations are used to identify wire
colors in the circuit schematics:
WHT . . . . . . . .White
YEL. . . . . . . ... Yellow
BLK . . . . . . . .. Black
BLU . . . . . . . .. Blue
GRN . . . . . . . . Green
RED . . . . . . . .. Red

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.
