Checking Opening of Tailgate, Power Operated Tailgate Module (POT)
Checking opening of tailgate
Checking the component
Power Operated Tailgate Module (POT) checks the voltage to the switch for the tailgate's external handle.
Check status for the external handle by clicking on the symbol for VCT2000. Status shall show pressed in when you press in the handle, and released when you do not press the handle.
If status shows pressed in even if there is no evident action, check the external handle with regards to the sensor having been displaced.

Checking the sensor
The Power Operated Tailgate Module (POT) checks the status of the boot lid closing motor, and the time it takes to close, using sensor 2 (outer lock position). Sensor 2 (outer lock position) shall be active when the lock is in either the outer or inner lock position and not active if the lock is open. Sensor 1 (inner lock position) shall only be active when the lock is completely closed and not active if the lock is open or in the outer lock position.
Check the sensors by:
- Click on the symbol for VCT2000 and read out status for sensors.
- Close the tailgate with the button on the tailgate's lower edge.
- Check that sensors changes status at the end of closing.
If status does not change for the sensors, the lock mechanism shall be replaced.

Checking the voltage
An opening of the tailgate, by Power Operated Tailgate Module (POT), does not normally take longer time than 12 seconds. In normal operation the voltage feed of motor tailgate opening shall be a PWM-signal with an amplitude bigger than 0 V and smaller than 12 V.
Check the voltage by clicking on the symbol for VCT2000 and read out the value of the battery. If the battery is poor, replace it.
Remedy as necessary.

Checking the button
When the button to open the tailgate is pressed in for at least 0.5 seconds, either on Light switch module (LSM), instrument panel or the remote key, the tailgate shall open to fully open position.
The tailgate's opening function is handled by control modules Central electronic module (CEM), Keyless Vehicle Module (KVM), and Power Operated Tailgate Module (POT).
Note! Keyless Vehicle Module (KVM) and Power Operated Tailgate Module (POT) are options and are not installed in all vehicles.
Check the buttons' status to open the tailgate by clicking on the symbol for VCT2000.
Status shall show pressed/not pressed for the button on the instrument panel, and for the remote key status shall show which button was pressed last. If the status does not follow the real button pushes, check if there are other trouble codes set for each control module.
