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.

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.

Switch failure
Description
This dtc is output when the sliding roof drive gear (sliding roof ecu)
detects that the slide open or
tilt up switch in the overhead junction block is stuck for 30 seconds or more. ...
Other materials:
All-wheel drive lock
switch (awd models)
All-wheel drive lock mode can be used when a large amount of
drive power needs to be applied to all the wheels, such as when
the vehicle gets stuck in mud and you need to free it.
Press the switch.

System too
Description
The fuel trim is related to the feedback compensation value, not to the basic
injection time. The fuel trim
consists of both the short-term and the long-term fuel trims.
The short-term fuel trim is fuel compensation that is used to constantly
maintain the air-fuel ratio at

Short in can bus lines
Description
There may be a short circuit between the can bus lines when the resistance
between terminals 6 (canh)
and 14 (canl) of the dlc3 is below 54
.
