I recently purchased an Autel MD802 for diagnosing / resetting an airbag reset on a 2003 Range Rover HSE. When I plug it in to read the code, it comes up with a code “50” and displays low voltage (9.6v) fault. I am assuming this fault was generated by a recent low battery event. However when I try to reset the fault it displays error in reading from the control unit and will not reset. Tried several times. Is there an update or something to get the unit to reset the airbag ECU?

Thank you!
