Laymans terms

This code means that the car's computer is having trouble understanding messages from the instrument panel, which shows things like speed and fuel level.

Explanation

The P3217 code is set when the vehicle's computer detects a problem with the messages it receives from the instrument cluster over the CAN bus.

Technical description

The Controller Area Network (CAN) bus is a communication system that allows different parts of the vehicle to communicate with each other. The instrument pack sends and receives messages over this network. If the vehicle's computer detects that the messages from the instrument pack are not plausible or consistent, it will set the P3217 code.
