Checking the button
The Power Operated Tailgate Module (POT) checks the boot lid closing switch. Check status for the closing button by clicking on the symbol for VCT2000. Status shall show pressed in when you press in the button, and released when you do not press the button.
If status shows pressed in even if there is no evident action, check that the tailgate's closing button is not jammed.
However, if status shows released even when the button is pressed in, this may be due to the lock mechanism. This is due to the tailgate's closing button grounding via the lock mechanism.
Is the button working?
Yes - Verification
No - Checking the cable
-------------------------------------------------
Checking the cable
Depending on if status shows that the tailgate's closing button was pressed in constantly or released, one of the following troubleshooting shall be performed.
In case of status constantly pressed in or released:
- Check the cable harness between Power Operated Tailgate Module (POT) and the tailgate's closing button.
- Also investigate the connector in Power Operated Tailgate Module (POT) and the connector for the tailgate's closing button with regards to loose connection and oxidation.
If status is constantly released, also check the grounding between the tailgate's closing button and the lock mechanism. Also check the lock mechanism's grounding.
If the leads are intact, closing button.
Remedy as necessary.
