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.

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.

terminal
Caution:
Wait at least 90 seconds after disconnecting the
cable from the negative (-) battery terminal to
prevent airbag and seat belt pretensioner activation.
