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

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 ...
Checking the battery
Check the battery as follows.
â– Battery exterior
Make sure that the battery terminals
are not corroded and that
there are no loose connections,
cracks, or loose clamps.
Terminals
Hold-down clamp
â– Before recharging
When recharging, the battery produces
hydrogen gas which is flammable
and exp ...
Terminals of ecu
Skid control ecu
Hint:
*1: W/ 16-inch disc
*2: W/ downhill assist control
*3: For 2wd (w/ auto lsd)
Check skid control ecu
Disconnect the a19 ecu connector.
Measure the voltage and resistance of the wire
harness side connector.
Hint:
The voltage cannot be measured ...
