B0785 CHEVROLET Description

 

The Two Wheel Drive High Range (2HI) indicator circuit consists of an LED dimming supply circuit and a 2HI indicator control circuit. When the 2HI mode is selected, current is supplied to the 2HI indicator by the LED dimming supply circuit, traveling through the 2HI LED indicator, at which time the transfer case shift control module supplies the ground through the 2HI indicator control circuit.
