  1. Check skid control ecu

Toyota RAV4. Check skid control ecu


  1. Disconnect the a19 ecu connector.
  2. Measure the voltage and resistance of the wire harness side connector.

Hint:

The voltage cannot be measured with the connector connected to the skid control ecu as the connector is water resistant.
