Toyota RAV4. Air conditioning amplifier communication stop mode


Inspection procedure

Notice:

Hint:

Operating the ignition switch, any switches or any doors triggers related ecu and sensor communication with the can, which causes resistance variation.

  1. Check can bus line for disconnection (air conditioning amplifier branch wire)

  1. Disconnect the e37*1 or e36*2 air conditioning amplifier connector.

Hint:

  1. Measure the resistance of the wire harness side connector.

Standard resistance: for automatic air conditioning system


For manual air conditioning system




  1. Check wire harness (air conditioning amplifier - battery and body ground)
