If the hands-free starting fault affects every card:
Make sure the UCH is properly configured for hands-free operation. Reconfigure if necessary.
Make sure that the cards belong to the vehicle and are properly configured by running command SC005 Check
card.
If the cards belong to the vehicle but are incorrectly configured, program the cards.
