Pinpoint Test U : The Lights On Indicator Is Never Or Always On: Notes

WARNING: This page is about a different car, the 2017 Lincoln Navigator and 2017 Ford Expedition. However, it is still accessible from the selected car via links, so may be relevant.

Diagnostic Overview 

See Lights On Indicator. Refer to Instrument Panel Cluster (IPC) .

Normal Operation and Fault Conditions 

If the park lamp status message is missing for less than 5 seconds, the IPC defaults the lights on indicator to its last indication state (on or off), based upon the last message received.

If the park lamp status message is missing for 5 seconds or longer, the IPC defaults the lights on indicator off.
