Hyundai/Kia Programming Voltage

Tanner Instructor Wellford, South Carolina Posted   Latest   Edited  

Anyone work at a hyundai/kia dealer or that can tell me what the programming voltage is set to on the gr8 charger for programming supply voltage or check for me? I’ve looked in service info but it appears the gr8 has hyundai/kia software that it is using because now voltage spec is given. I know what acceptable ranges are but am looking to know what the dealer charger is set to as I need it for a project.

The GR8 is set to a charging voltage of 13.5 volt. when it set to power supply mode. I don’t work at the Kia dealer but we do have as part of the franchise. I called that’s what the shop Forman said.

Hyundai vehicles are not as sensitive as dodge, ford, bmw, mercedes etc. Eeven if you keep it at 12.7v no issues at all. 13.5 is a general rule for 99% of vehicle programming.

Less 11,8V is not good. I use smart charger in supply mode(constant 13,5V) for programming
