Toyota RAV4 (XA40) 2013-2018 Service Manual: Air conditioning amplifier communication stop mode
Description
Wiring diagram
Inspection procedure
Notice:
- Turn the ignition switch off before measuring the resistances
of the main wire and the branch
wire.
- After the ignition switch is turned off, check that the key
reminder warning system and light
reminder warning system are not in operation.
- Before measuring the resistance, leave the vehicle for at least
1 minute and do not operate the
ignition switch, any switches or doors. If doors need to be opened in order
to check
connectors, open the doors and leave them open.
Hint:
Operating the ignition switch, any switches or any doors triggers related ecu and sensor communication with the can, which causes resistance variation.
- Check can bus line for disconnection (air conditioning amplifier branch wire)
- Disconnect the e37*1 or e36*2 air conditioning amplifier connector.
Hint:
- *1: For automatic air conditioning system.
- *2: For manual air conditioning system.
- Measure the resistance of the wire harness side connector.
Standard resistance:
for automatic air conditioning system
For manual air conditioning system
- Check wire harness (air conditioning amplifier - battery and body ground)
- Disconnect the e37*1 or e36*2 air conditioning amplifier connector.
Hint:
- *1: For automatic air conditioning system.
- *2: For manual air conditioning system.
- Measure the resistance of the wire harness side connectors.
Standard resistance:
for automatic air conditioning system
For manual air conditioning system
- Measure the voltage of the wire harness side connector.
Standard voltage:
for automatic air conditioning system
For manual air conditioning system
Replace air conditioning amplifier

All-wheel drive lock
switch (awd models)
All-wheel drive lock mode can be used when a large amount of
drive power needs to be applied to all the wheels, such as when
the vehicle gets stuck in mud and you need to free it.
Press the switch.
The torque of the engine is distributed
to the rear wheels to the maximum
extent possible in
