Toyota RAV4. 4Wd 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 for disconnection (4wd control ecu branch wire)
