Toyota RAV4 (XA40) 2013-2018 Service Manual: 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.
