Toyota RAV4. Main body ecu 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 (main body ecu branch wire)

  1. Disconnect the e17 main body ecu connector.
  2. Measure the resistance of the wire harness side connector.

Standard resistance




  1. Check wire harness (main body ecu - battery and body ground)
