How to Use This Chapter
This chapter contains a set of general
troubleshooting guidelines, a troubleshooting
task flow, and a set of troubleshooting tables for
symptoms not accompanied by a fault code.
Use the START TROUBLESHOOTING Chart
individual symptom chart you need.
Use the Symptom Tables to identify possible
causes of problems that are not accompanied
by a fault code on the Operator Display.
As you work with a troubleshooting symptom
chart, you may be instructed to test various
electrical connector pins. Use the Electrical
Connector Locator Chart on Page 5- 18.
Every time you complete a troubleshooting
procedure, be sure to follow the steps in End of
Troubleshooting Chart END1 on Page 5-28.
Another troubleshooting resource is the
Pinout Matrix on Page 9-5 1 in the Theory of
Operation chapter. The pinout matrix chart lists
functions and normal voltages of terminals and
harness connector pins.
If the troubleshooting symptom charts do not
isolate the problem, or if the symptoms are not
consistent or repeatable, go to the General
Troubleshooting Chart GENl on Page 5-28.
This chart will help you approach the problem
in a systematic and logical manner.
