Hint:
- Use these procedures to troubleshoot the air conditioning
system.
- *: Use the intelligent tester.
- Vehicle brought to workshop

- Customer problem analysis and symptom check
- Inspect battery voltage
Standard voltage:
11 to 14 v
If the voltage is below 11 v, recharge or replace the battery
before proceeding.
- Check can communication system*
- Use the intelligent tester to check if the can
communication system is functioning.
Result 

- Check dtc*
- Check for dtcs and write down any dtcs that are
output.
- Clear the dtcs.
- Recheck for dtcs. Based on the dtcs output above, try
to cause output of the air conditioning system dtc by
simulating the operation indicated by the dtc.
Result 

- Refer to problem symptoms table
Result 

- Overall analysis and troubleshooting*
- Data list / active test (see page ac-127)

Symptom confirmation and diagnostic trouble code
Hint:
The diagnostic system in the rav4 has various
functions.
The first function is the diagnostic trouble code
(dtc) check. A dtc is a code stored in the ecu
memory whenever a malfunction in the signal circuits
to the ecu occurs. In a dtc check, a previous
malfunction's dtc can be ch ...
