Towbar, to work correctly, requires a module. This is responsible for CAN communication with other modules:

• Engine - when towing it works differently to cope with extra load - sometimes switches additional fan to cool
• ABS / ESP module - these work differently when trailer is hooked to avoid jack knifing. 
• CECM - This power module distributes power in another way when trailer is hooked - also visually aids the driver when trailer is hooked on dashboard 
• OPS - This is coded so when trailer is hooked up sensors do not beep
• CAN gateway - trailer module is coded into the gateway (main comms hub) so the car and other modules know what to do
• RVC - reversing camera - similar thing to parking sensors - recognises the trailer on the screen switches off dynamic lines
• Information Electronics - ensures entertainment system displays all the trailer info correctly.
