*6.6 L Duramax Diesel will only

The 091-84-ETM64 system can be set up to use either the engine
data bus message for the parking brake interlock or a hardwired
input from the parking brake switch.
Five available modes of fast engine idle operation include three
preset fixed speeds, a variable speed control via an external
potentiometer, and
which will automatically
increase engine speed to maintain the battery charge. Ten
LED indicators are provided to display the selected operating
mode, system status, and error conditions. A set-up jumper
option is provided that can allow the air conditioner system to
either be enabled or disabled during fast idle operation
(disabling the A/C allows for a more stable engine speed).
