Checking electrically convertible hardtop

Introduction
This troubleshooting is used when electrically fold-down hardtop cannot be operated and no diagnostic trouble codes are generated. Probably because any hall sensor or position sensor has become displaced. Start first by excluding other problem causes.
Fault-trace and remedy stored diagnostic trouble codes (DTCs).
To exclude that the hardtop has stopped due to an earlier problem, it is necessary to restart the control module.
Click on the symbol for VCT2000 to restart the control module.

Picture 3. Opening of hardtop
The following takes place in this stage of sunroof operation:
The tonneau cover is extended and locked.
During the roof operation procedure that has not started, the following applies:
The hardtop's middle part is released from the hardtop's front and rear part. The hardtop's front part is lifted up.
Activate read-out of the hall sensors' and position sensors' values in the folded hardtop by clicking on the symbol for VCT2000.
Compare the read-out values with the normal value that also is shown. If any value does not match, click on the button that has the same number as the hall sensor or position sensor has, which shows an incorrect value. If all hall sensors or position sensors show right, click on OK to finish troubleshooting.

Were any defects found?

Yes - Verification

No - Choice of operation

-------------------------------------------------

Choice of operation
1. For opening of hardtop.
2. For closing of hardtop.
3. For start of loading assistance function.
4. For finishing loading assistance function.

During which operation does the hardtop stop?

1 - Opening the roof

2 - Closing of hardtop

3 - Start of loading assistance function

4 - Finishing loading assistance function

-------------------------------------------------

Opening the roof
Check that the trunk lid is closed.
Check that the luggage compartment's divider is closed.
Press down the brake before opening or closing the hardtop.
Run until the hardtop stops and release the button immediately when the hardtop has stopped.
The hardtop's movement consists of several steps. For next step to begin, the previous must have finished. If position sensor or hall sensors do not have the values they should, the hardtop stops. The link below shows pictures of the positions where the hardtop movement goes from one step to the next. For some reason the position sensors and hall sensors have not reached their end values for respective step. This results in the next step not being able to start.
To decide which hall sensor is not working. Click on the link below and compare the pictures with the position that the hardtop is in. Choose the button that matches the position in which the hardtop has stopped.
