Troubleshooting Toyota Pallet Truck Service Manual How to Use This Section How to Use This Section This section uses a set of fault, caution, and error codes, charts, and tables that are designed to take you from a symptom to a specific sequence of actions in order to isolate a failing component. The chart “Traction Power Amplifier Flash Codes” on page 5-27 will guide you thru the flash codes displayed on the LED’s installed on the TA. The section “Caution and Error Codes” on page 5-33 will define the various codes displayed on the operator display. Use the chart “TS1: START TROUBLESHOOTING” on page 5-29 to guide you to the individual symptom chart you need.
When you’re familiar with the symptoms listed, you may instead simply look up the symptom in the “Troubleshooting” on page 5-29 . As you work with a troubleshooting chart, code, or table, you may be instructed to test various electrical connector pins. The pinout matrix chart lists information on functions and normal voltages of terminals and harness connector pins. See “Pinout Matrix” on page 5-69. Every time you complete a troubleshooting procedure, follow the steps in the “END1: End of Troubleshooting Procedure” on page 5-31. If the troubleshooting symptom charts, codes, or tables do not isolate the problem, or if the symptoms are not consistent or repeatable, go to “GEN1:
General Troubleshooting” on page 5-30. This chart will help you approach the problem in a systematic and logical manner. 5-2 00700-CL398-07, Issued: 9 August 2007
