How to Use This Chapter
How to Use This Chapter This section uses “decision-tree” charts and symptom tables designed to take you from a symptom to a specific sequence of tests in order to isolate a failing component. •
Use the “TS1: START TROUBLESHOOTING” on page 5-31 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 chart from the “List of Troubleshooting Charts/Tables” on page 5-29.
As you work with a troubleshooting symptom table, you may be instructed to test various electrical connector pins. Every time you complete a troubleshooting procedure, make sure you follow the steps in the “END1: End of Troubleshooting Procedure” on page 5-33. If the troubleshooting symptom tables do not isolate the problem, or if the symptoms are not consistent or repeatable, go to “GEN1: General Troubleshooting” on page 5-31. This chart will help you approach the problem in a systematic and logical manner.
