Johno,

A communication error on the display indicates the dash display and main interface board (MIB) have lost communication. Check the #81, 82, 83 and 85 wires from the display to the MIB circuits for an open circuit. Also remove the J2 MIB connector and inspect the J2-3, J2-11, J2-15, and J2-18 pins in the plug for any pushed out pins or spread pins.

Fact of the week
The two internal cavities in our nose called nostrils function as separate organs. Each nostril has its own set of turbinates and olfactory receptors. The two independent organs work together through a mechanism called the nasal cycle, where one nostril is dominant for air intake while the other rests and is better at detecting scents.
