Toyota RAV4. Main body 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 (main body ecu branch wire)

Compressor solenoid circuit (2006/01- )
Description In this circuit, the compressor receives a refrigerant compression demand signal from the air conditioning amplifier. Based on this signal, the compressor changes the degree of refrigerant compression. Hint: *: Compressor and pulley for 2az-fe, compressor and magnetic clu ...

Camshaft position sensor "a" circuit (bank 1 or single sensor)
Description The camshaft position (cmp) sensor consists of a magnet and an iron core which is wrapped with copper wire, and is installed onto the cylinder head. When the camshaft rotates, each of 3 teeth on the camshaft passes through the cmp sensor. This activates the internal magnet in ...
