Toyota RAV4. Control module communication bus off

Description

The power steering ecu receives signals from the ecm and the skid control ecu via the can communication system.

Hint:

When 2 or more dtcs starting with [u] are output simultaneously, inspect the connectors and wire harness of each ecu.
If dtc u0105/41 is output, first erase the dtcs. Then turn the ignition switch from off to on. If dtc u0105/41 is not output again, there is no malfunction.
