F1-F3:

Normal Operation
The audio unit receives input signals through the medium speed controller area network (CAN) and the audio control protocol (ACP) module. The navigation system then computes and displays the high energy power flow and miles per gallon data when selected.

Possible Causes
- circuit 1847 (WH/OG) open
- circuit 1848 (PK/OG) open
- ACP module
- instrument cluster
