PRNDL/Vehicle Odometer/Trip Odometer (Hybrid)
WARNING: This page is about a different car, the 2007 Mercury Mariner and 2007 Ford Escape. However, it is still accessible from the selected car via links, so may be relevant.
The PRNDL indicates the transmission position selection. This is done in the first line of the PRNDL/vehicle odometer/trip odometer LCD display. Each PRNDL character has a box surrounding it. The only time that the box segment is activated is when the requirements are met to display the transmission position selected. The input to the instrument cluster is a hardwired input from the redundant park relay and a message from the PCM over the communication network.
