Telematics Control Unit Update: Procedure

NOTE:

This procedure can update the telematics software or the HFL software in the telematics control unit.
Before you update the telematics control unit, check the vehicle battery condition first - Refer to: Battery Test (2014 2015), or Battery Test (2016) , and connect a jumper battery (not a battery charger) to maintain system voltage.
Never turn the vehicle to the OFF (LOCK) mode during the update. If there is a problem with the update, leave the vehicle in ON mode.
To ensure the latest program is installed, do a telematics control unit update whenever the telematics control unit is substituted or replaced.
The telematics control unit is updated via Bluetooth using the update application on the HDS PC. Make sure the HDS PC is inside the vehicle when updating the telematics control unit.
