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).

terminals.
FIVE-STEP TROUBLESHOOTING
1. Verify The Complaint
Turn on all the components in the problem circuit to verify the clients 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:
