Control module




The task of the Power Operated Tailgate Module (POT) is to control the automatic operation of the boot lid. The control module monitors the movement, both when closing and opening, and can cancel it if something prevents the movement. The control module also monitors whether it is possible to open/close the boot lid.
The Power Operated Tailgate Module (POT) is located in the left in the tailgate, in front of the tailgate panel.
Power Operated Tailgate Module (POT) communicates via the MS CAN-net with Central electronic module (CEM) and Keyless Vehicle Module (KVM).
The control module checks activations and input and output signals via an integrated diagnostic system.
A diagnostic trouble code (DTC) is stored if the control module detects an error. In certain cases the control module replaces the faulty signal with a substitute value.
Any diagnostic trouble codes (DTCs) are stored in the control module memory. This information can be read off using the diagnostic tool via the data link connector (DLC) in the vehicle.
