The contact owns a 2020 Toyota Highlander equipped with a Tekonsha Prodigy RF Electronic Brake Control with Bluetooth kits, part number 902501. The contact purchased the unit to use for towing a trailer. The contact purchased the part at an independent mechanic and had the equipment installed by another independent mechanic. When the contact first attempted to use the brake kit, her and her husband had connected the equipment per the instructions and brake kit showed the letter "C" which meant the part was connected. As the contact started driving the vehicle, a NC (not connected) message had appeared on the brake kit. The contact decided to drive the vehicle back to her home and attempted to reconnect the brake system as instructed but the failure persisted.
