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

WARNING: This page is about a different car, the 2018 Ford Focus. However, it is still accessible from the selected car via links, so may be relevant.

Normal Operation and Fault Conditions 

See Lights On Indicator. REFER to: INSTRUMENT PANEL CLUSTER (IPC) - SYSTEM OPERATION AND COMPONENT DESCRIPTION

If the position light indication message is missing for less than 2 seconds, the IPC defaults the lights on indicator to its last state (on or off) based upon the last known good message received.

If the position light indication message is missing for 2 seconds or longer, the IPC sets DTC U0140:00 in continuous memory and defaults the lights on indicator off.
