Toyota RAV4 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

1. Check sliding roof function

1. 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.

2. Delete dtc

1. Delete the dtc (see page rf-7).

End

3. Initialize sliding roof drive gear sub-assembly (sliding roof ecu)

1. Check that the sliding roof drive gear can be initialized (see page rf-4).

Ok: sliding roof drive gear can be initialized.

4. Check sliding roof function

1. 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.

5. Delete dtc

1. Delete the dtc (see page rf-7).

End

6. Check wire harness (sliding roof drive gear - overhead junction block)

1. Disconnect the p6 ecu connector.
2. Disconnect the p5 junction block connector.
3. Measure the resistance of the wire harness side connectors.

Standard resistance

7. Inspect overhead junction block (sliding roof control switch)

1. Remove the overhead junction block.
2. Measure the resistance of the switch.

Standard resistance

Replace sliding roof drive gear sub-assembly (sliding roof ecu)
