Toyota RAV4 (XA40) 2013-2018 Service Manual: 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
- Reconfirm dtc
- Check for dtc.
Ok: dtc is not output.
Replace power steering ecu

Assist map number un-writing
Description
The power steering ecu outputs this dtc when it determines that the assist
map is not written in the
ecu.

Shift solenoid "d" performance (shift solenoid valve s4)
System description
The ecm uses signals from the output shaft speed sensor and input speed
sensor to detect the actual
gear position (1st, 2nd, 3rd or o/d gear).
Then the ecm compares the actual gear with the shift schedule in the ecm memory
to detect mechanical
problems of the shift s ...
Communication
Description
The skid control ecu sends signals such as cruise control cancel demand
signals and brake operation
demand from ecm response signals to the ecm when the cruise control system is in
operation.
Inspection procedure
Hint:
This circuit uses can communication. Therefore, if t ...
