Toyota RAV4. Combination meter 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 wire harness (combination meter ecu - battery and body ground)
