Toyota RAV4 Service Manual: Sensor (motor) failure

Toyota RAV4. 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.

Toyota RAV4. Sensor (motor) failure


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.



  1. Delete dtc

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


End

  1. 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.



  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.



  1. Delete dtc

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

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

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. When the roof glass is ...

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. ...

Input speed sensor circuit no signal
Description This sensor detects the rotation speed of the turbine, which shows the input revolution of the transaxle. By comparing the input speed signal (nt) with the counter gear speed sensor signal (nc), the ecm detects the shift timing of the gears and controls the engine torque and ...

Terminals of ecm
Check ecm Disconnect the a9 and b30 connectors. Measure the voltage and resistance of the wire harness side connectors. If the result is not as specified, there may be a malfunction on the wire harness side. ...

Terminals of ecm
Hint: The standard normal voltage between each pair of ecm terminals is shown in the table below. The appropriate conditions for checking each pair of terminals are also indicated. The result of checks should be compared with the standard normal voltage for that pair of terminals, displayed ...
