Toyota RAV4 (XA40) 2013-2018 Service Manual: How to proceed with troubleshooting (2005/11-2006/01)
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)
- Terminals of ecu (see page ac-122)
- Adjust, repair or replace
- Confirmation test

Sleep operation failure of occupant classification ecu
Description
During sleep mode, the occupant classification ecu reads the condition of
each sensor while the ignition
switch is off.
In this mode, if the occupant classification ecu detects an internal
malfunction, dtc b1796 is output.
Inspection procedure
Check for dtc

Compressor lock sensor circuit
Description
This sensor sends 1 pulse per engine revolution to the air conditioning
amplifier. If the ratio of the
compressor speed divided by the engine speed is smaller than a predetermined
value, the air conditioning
amplifier turns the compressor off, and the indicator blinks at appro ...

Description
Inspection procedure
Notice:
It is necessary to register an id code after replacing the tire pressure
warning valve and
transmitter and/or the tire pressure monitor ecu (see page tw-9).
Hint:
Set the tire pressure to the specified value.
Standard pressure:
220 kpa (2.2 ...
