4.3 V6 Volvo Cruise and Trim assist not working
 

I have a Volvo Penta 4.3 V6 with the throttle control below. I am not sure if the cruise and trim assist is pre installed or added option, the tow function works. I have contacted Volvo South Africa and no one can help me. If I try and calibrate the EVC tells me to contact a authorized dealer. Any help would be appreciated
