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)
