Using the Flowcharts

TROUBLESHOOTING NOTES
^ Precise understanding of customer complaints is the key to diagnosing problems.
^ Diagnosis of air conditioning system problems can be difficult because of the surrounding temperatures. Therefore, checking the system operation is important. Further checking the system operation in a logical order is necessary for the accurate understanding of problems.


USING THE FLOWCHARTS
When troubleshooting, follow the procedure shown below.





Note the following points when using the flowcharts.




1. Only those parts, connectors, and harnesses that are directly related to the item being checked are indicated in the wiring diagram.
2. Follow the steps in order when troubleshooting the system.
3. Before inspection, turn all switches to OFF. When moving from step to step, keep the switches, connectors, and jumper wire in their former position unless otherwise instructed.
Before connecting or disconnecting a jumper wire, turn the ignition switch to LOCK to prevent burning the electrical parts. After the jumper wire is connected or disconnected, the ignition switch can be turned to ON again.
4. When checking for continuity of the wiring harness, the terminal names are shown under "Terminal" and their corresponding connector names are shown under "Inspection procedure." When repairing the wiring harness, the terminal names and the corresponding part names to which they are connected are shown under "Action."





5. Inspect connectors from either the male or female side stated after the connector name.





6. When more than one connector is attached to the same part, the pin number enclosed in ( ) after the connector name distinguishes the connectors.
The wiring diagram connector number shown before alphabet letter distinguishes the terminals.





7. When more than one harness connects two different parts, the wiring diagram connector number enclosed in ( ) after the connector name distinguishes the connectors.
