Toyota RAV4 (XA40) 2013-2018 Service Manual: Power supply relay failure

Toyota RAV4. Power supply relay failure


Description

If the power steering ecu detects these dtcs, it shuts off the motor relay circuit (built into the power steering ecu) and stops power assist.


Inspection procedure

  1. Reconfirm dtc

  1. Check for dtc.

Ok: dtc is not output.
