Toyota RAV4. Abs and traction actuator (skid control 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 disconnection (abs and traction actuator branch wire)

  1. Disconnect the a19 abs and traction actuator (skid control ecu) connector.
  2. Measure the resistance of the wire harness side connector.

Standard resistance




  1. Check wire harness (abs and traction actuator - battery and body ground)

Check for intermittent problems Hint: A momentary interruption (open circuit) in the connectors and/or wire harness between the sensors and ecus can be detected by using the ecu data list function of an intelligent tester. Turn the ignition switch off and connect the intelligent test ...

Do-it-yourself service precautions
If you perform maintenance by yourself, be sure to follow the correct procedure as given in these sections. Caution The engine compartment contains many mechanisms and fluids that may move suddenly, become hot, or become electrically energized. To avoid death or serious injury, obse ...

Handling of hose clamps
Before removing the hose, check the clamp position so that it can be reinstalled in the same position. Replace any deformed or dented clamps with new ones. When reusing a hose, attach the clamp on the clamp track portion of the hose. For a spring type clamp, you may want to spread ...
