PRNDL Display

The PRNDL displays light to indicate the gear position selected for the automatic transmission. The PRNDL circuit board is part of the instrument cluster. The PRNDL is powered from the TRANS Fuse 24 when the ignition is turned to the RUN position. The circuit board is grounded by the CKT 451 (BLK/WHT) wire to Ground G101. The module receives 4 grounded inputs from the park/neutral position switch. A combination of 2 - 4 of these inputs are grounded by the park/neutral position switch depending on the gear position selected for the automatic transmission. The PRNDL circuit board evaluates the inputs and light the appropriate display. Refer to Interior Lights Dimming Schematics for information on PRNDL indication illumination. Description and Operation
