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.

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. ...

Engine immobiliser system malfunction
Description
This dtc is output when one of the following occurs: 1) the ecm detects
errors in its own
communications with the transponder key ecu; 2) the ecm detects errors in the
communication lines; or
3) the ecu communication id between the transponder key ecu and ecm is different

Checking the coolant
The coolant level is satisfactory
if it is between the "FULL" and
"LOW" lines on the reservoir
when the engine is cold.
Reservoir cap
"FULL" line
"LOW" line
If the level is on or below the "LOW" line, add coolant up to the "FULL"
line.

Pressure control solenoid "A" electrical (shift solenoid valve sl1)
Description
Shifting from 1st to o/d is performed in combination with the on and off
operation of the shift solenoid
valves sl1 and sl2, which are controlled by the ecm. If an open or short circuit
occurs in any of the shift
solenoid valves, the ecm controls the remaining normal shift soleno ...
