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. ...

Torque converter clutch solenoid circuit
Description
The shift solenoid valve dsl is turned on and off by signals from the ecm to
control the hydraulic
pressure acting on the lock-up relay valve, which then controls operation of the
lock-up clutch.
Fail-safe function:
if the ecm detects a malfunction, it turns the shift sol ...
How to proceed with troubleshooting
Hint:
Use these procedures to troubleshoot the sliding roof
system.
*: Use the intelligent tester.
