Toyota RAV4 (XA40) 2013-2018 Service Manual: Sensor (motor) failure
Description
When the sliding roof drive gear (sliding roof ecu) detects the motor's malfunction, and the sliding roof operation is stopped, dtc b2341 is output. When the sliding roof drive gear (sliding roof ecu) detects the gear's malfunction, and the sliding roof operation is stopped, dtc b2344 is output.
Wiring diagram
Inspection procedure
- Check sliding roof function
- Check the auto operation with the slide open and tilt up switch (see page rf-9).
Ok: auto operation operates normally with slide open and tilt up switch.
- Delete dtc
- Delete the dtc (see page rf-7).
End
- Initialize sliding roof drive gear sub-assembly (sliding roof ecu)
- Check that the sliding roof drive gear can be initialized (see page rf-4).
Ok: sliding roof drive gear can be initialized.
- Check sliding roof function
- Check the auto operation with the slide open and tilt up switch (see page rf-9).
Ok: auto operation operates normally with slide open and tilt up switch.
- Delete dtc
- Delete the dtc (see page rf-7).
End
- Check wire harness (sliding roof drive gear - overhead junction block)
- Disconnect the p6 ecu connector.
- Disconnect the p5 junction block connector.
- Measure the resistance of the wire harness side connectors.
Standard resistance 
- Inspect overhead junction block (sliding roof control switch)
- Remove the overhead junction block.
- Measure the resistance of the switch.
Standard resistance 
Replace sliding roof drive gear sub-assembly (sliding roof ecu)
On-vehicle inspection
Hint:
When pressing the switch for 0.3 Seconds or less, the roof
glass moves but auto operation does not operate.
Check auto operation
Turn the ignition switch on.

â– Operation of the RCTA
function
The RCTA function uses rear
side radar sensors to detect
vehicles approaching from the right or left at the rear of the
vehicle and alerts the driver of
the presence of such vehicles
by flashing the outside rear view
mirror indicators and sounding a
buzzer.

Occupant classification system malfunction
Description
The occupant classification system circuit consists of the center airbag
sensor and the occupant
classification system.
When the center airbag sensor receives signals from the occupant classification
ecu, it determines
whether or not the front passenger airbag, front seat side ...
Data list / active test
Read data list
Hint:
Using the intelligent tester's data list allows switch,
sensor, actuator and other item values to be read without
removing any parts. Reading the data list early in
troubleshooting is one way to save time.
Connect the intelligent tester to the dlc3.
