Toyota RAV4 (XA40) 2013-2018 Service Manual: Steering angle sensor circuit malfunction

Description
The steering sensor signal is sent to the skid control ecu via the can
communication system. When
there is a malfunction in the can communication system, it is detected by the
steering sensor zero point
malfunction diagnostic function.

Inspection procedure
Hint:
- When u0073/94, u0123/62, u0124/95 or u0126/63 is output together with
c1231/31, inspect and
repair the trouble areas indicated by u0073/94, u0123/62, u0124/95 or
u0126/63 first.
- When there are problems with the speed sensor or the yaw rate sensor,
dtcs for the steering sensor
may be output even when the steering sensor is normal. When dtcs for the
speed sensor or yaw rate
sensor are output together with other dtcs for the steering sensor, inspect
and repair the speed
sensor and yaw rate sensor first, and then inspect and repair the steering
sensor.
- Check harness and connector (momentary interruption)
- Using the data list of the intelligent tester, check for
any momentary interruptions in the wire harness and
connectors between the skid control ecu and the
steering sensor (see page bc-23).

Ok:
there are no momentary interruptions.
Hint:
Perform the above inspection before removing the
sensor and connector.

- Check dtc
- Clear the dtc (see page bc-47).
- Turn the ignition switch off
- Turn the ignition switch on again and check that no can
communication system dtc is output.
- Drive the vehicle and turn the steering wheel to the right
and left at a speed of 35 km/h (24 mph) and check that
no speed and yaw rate sensor dtcs are output.
Result 

- Check wire harness (steering sensor - battery and body ground)

- Remove the steering wheel assembly and the column
cover.
- Disconnect the e11 sensor connector.
- Measure the voltage of the wire harness side connector.
Standard voltage 
- Measure the resistance of the wire harness side
connector.
Standard resistance 

Replace steering sensor
- Repair or replace harness and connector (steering sensor to skid
control ecu)
- Reconfirm dtc
- Clear the dtc (see page bc-47).
- Start the engine.
- Drive the vehicle and turn the steering wheel to the right
and left at a speed of 45 km/h (28 mph) or more for
several seconds.
- Check if the same dtc is recorded (see page bc-47).

Mil circuit
Description
The mil (malfunction indicator lamp) is used to indicate vehicle malfunction
detections by the ecm.
When the ignition switch is turned on, power is supplied to the mil circuit, and
the ecm provides the
circuit ground which illuminates the mil.
The mil operation can be checked ...
