Pinpoint Test Ai : The Water In Fuel Indicator Is Never Or Always On
- Normal Operation and Fault Conditions
See Water In Fuel Indicator. REFER to: Instrument Panel Cluster (IPC) - System Operation and Component Description .
If the water in fuel message is missing or invalid for less than 5 seconds, the IPC defaults the water in fuel indicator or water in fuel indicator to its last state (on or off) based upon the last message received.
If the water in fuel message is missing for 5 seconds or longer, the IPC defaults the water in fuel indicator or water in fuel indicator off.
