How To Follow Trouble Diagnosis

How to Follow Trouble Diagnosis

DESCRIPTION

NOTE: Trouble diagnosis indicate work procedures required to diagnose problems effectively. Observe the following instructions before diagnosing.

1. Before performing trouble diagnosis, read the "Preliminary Check", the "Symptom Chart "or the "Work Flow.
2. After repairs, re-check that the problem has been completely eliminated.
3. Refer to Component Parts and Harness Connector Location for the Systems described in each section for identification/location of components and harness connectors.
4. Refer to the Circuit Diagram for quick pinpoint check.
If you need to check circuit continuity between harness connectors in more detail, such as when a sub-harness is used, refer to Wiring Diagram in each individual section and Harness Layout in Power Supply, Ground & Circuit Elements, for identification of harness connectors.

5. When checking circuit continuity, ignition switch should be OFF.
6. Before checking voltage at connectors, check battery voltage.
7. After accomplishing the Diagnostic Procedures and Electrical Components Inspection, make sure that all harness connectors are reconnected as they were.




HOW TO FOLLOW TEST GROUPS IN TROUBLE DIAGNOSIS
1. Work and diagnostic procedure
Start to diagnose a problem using procedures indicated in enclosed test groups.

2. Questions and required results
Questions and required results are indicated in bold type in test group.
The meaning of are as follows:

a.Battery voltage equals 11 - 14 V or approximately 12 V
b.Voltage: Approximately 0 V equals Less than 1 V

3. Symbol used in illustration
Symbols included in illustrations refer to measurements or procedures. Before diagnosing a problem, familiarize yourself with each symbol. Refer to "Connector Symbols" and "KEY TO SYMBOLS SIGNIFYING MEASUREMENTS OR PROCEDURES".

4. Action items
Next action for each test group is indicated based on result of each question. Test group number is shown in the left upper portion of each test group.
