Tow Assist: Notes

Tow Assist aids the driver with the reversing of a trailer by displaying information on the TSD (touch screen display).

The system uses a tracking target sticker attached to the trailer to monitor and predict the direction of the trailer. Calculations are made by the proximity camera control module, based on the relationship of angles between the vehicle and trailer and the current steering wheel position.

Tow Assist becomes active when a trailer is attached to the vehicle and the trailer electrical plug is attached to the vehicle socket. The central junction box (CJB) detects the connection has been made and sends a message via the medium speed controller area network (CAN) to the proximity camera control module.
