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
