Additionally, the ProCal Module is the only product of its kind that allows the user to recalibrate the TPMS system for larger diameter tires that have a lower inflation pressure than the stock tires – a common scenario that would otherwise lead to an annoying low tire pressure warning light. The ProCal will also recalibrate for axle gear ratio changes, allow users to turn the truck’s one-touch lane change feature on or off and determine whether or not the fog lights turn off or stay on with the high beams (for off-road use only).
The ProCal Module is equipped with a series of easy-to-use DIP switches. By reading the simple instructions included with the ProCal module, the user can quickly dial in a code for the desired recalibration. The entire process can be completed in mere minutes – once the switches are set, simply plug the ProCal Module into the vehicle's OBDII and wait for the horn to honk, confirming that the setting has taken effect.
