Switch failure

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.

Refer to dtc b2341 (see page rf-11).

1. 1
   Read value of intelligent tester (slide open and tilt up switch)
2. 2
   Use the data list to check if the sliding roof control switch is functioning properly.

1. 1
   Check sliding roof function
2. 2
   Check the auto operation with the slide open and tilt up switch (see page rf-9).

1. 1
   Delete dtc
2. 2
   Delete the dtc (see page rf-7).

   

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

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

Standard resistance

1. 1
   Replace overhead junction block (sliding roof control switch)
2. 2
   Temporarily replace the overhead junction block (sliding roof control switch) with a new or normally functioning one (see page rf-9).

   

1. 1
   Delete dtc
2. 2
   Delete the dtc (see page rf-7).

   

1. 1
   Initialize sliding roof drive gear sub-assembly (sliding roof ecu)
2. 2
   Check that the sliding roof drive gear can be initialized (see page rf-4).

1. 1
   Check sliding roof function
2. 2
   Check the auto operation with the slide open and tilt open switch (see page rf-9).

1. 1
   Delete dtc
2. 2
   Delete the dtc (see page rf-7).

   

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

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