Circut Description

The PRNDL Indicator indicates the gear selection for Automatic Transmissions. The PRNDL Indicator receives coded input through four wires from the Transmission Range Selector (part of the Park/Neutral Position Switch). Depending upon which combination of the four wires to the PRNDL Indicator are grounded, a gear selection indication light emitting diode (LED), e.g. Reverse (R), is illuminated. The indications are separate from the Transmission's inputs to the Vehicle Control System.
