TROUBLESHOOTING

1-3. Before Starting

The information in this section is provided to assist the troubleshooter in understanding the systems and quickly
determine the causes when operating abnormalities occur.
The following steps are recommended:
1. If not familiar with the machine, study the Operator’s Manual and this Shop Manual.
2. Check with the operator for full details of the trouble, ask questions.
3.  Verify the trouble by warming up the machine and operating it. Check the problem yourself.
4. Identify the problem with either a mechanical, hydraulic or electrical system source.
5. Isolate the problem to a particular component or circuit.
6.  Eliminate the simplest or easiest to check possibilities first to prevent unnecessary disassembly of components.
7.  Following repair or replacement of any parts, perform operational tests to verify that the problem has been

eliminated and the performance of all the systems is normal.

1-4. Wire Number and Color Code

Refer to “1-1. wire Numbers, wire Sizes, wire Colors and Connectors Shown in Electrical Circuit Diagram, wiring
Harness Layout and wiring Harnesses” of ELECTRICAL SYSTEM.
