Toyota RAV4 (XA40) 2013-2018 Service Manual: 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.
Hint:
The assist map data is written in the power steering ecu to control assisting power.
The assist map has 3 types. Select an assist map according to the vehicle
country information that is
recorded in the ecu.
Inspection procedure
- Perform assist map writing
- Turn the ignition switch on.
- Connect the intelligent tester (with can vim) to the dlc3.
Hint:
At this time, check that the p/s warning light is illuminated.
- Select signal check, and change to test mode.
- Wait for 3 seconds.
- Check p/s warning light
- Check the p/s warning light.
Result
Hint:
If the p/s warning light blinks at 0.25 Second intervals, the assist map adjustment has completed normally.
- Check dtc
- Check for dtc.
Result
Hint:
If dtc c1581/26 is output, turn the ignition switch off. Enter test mode again. If the dtc is output 3 times in a row, replace the power steering ecu.
Replace power steering ecu
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

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 simul ...

Insufficient coolant temperature for closed loop fuel control
Description
Refer to dtc p0115 (see page es-105).
Monitor description
The resistance of the ect sensor varies in proportion to the actual ect. The
ect supplies a constant
voltage to the sensor and monitors the signal output voltage of the sensor. The
signal voltage output
varies acc ...
Downhill assist control operation switch (test mode dtc)
Description
The downhill assist control switch is connected to the skid control ecu in
the abs and traction
actuator.
Dtc c1379/74 can be detected when the downhill assist control switch sends the
downhill assist control
switch signal or test mode ends. Dtc c1379/74 is output only in t ...
