Pinpoint Test Ad : The TPMS Warning 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.

Normal Operation and Fault Conditions 

See TPMS Warning Indicator. Refer to Instrument Panel Cluster (IPC) .

NOTE: If DTC U0140:00 sets in the IPC, other symptoms can also be present such as an inoperative high beam indicator, LH -RH turn indicators, instrument panel backlighting, and door ajar indication.

If the tire pressure indicator message is missing for 5 seconds or less, the TPMS warning indicator remains in its last indication state (on or off) based on the last message received.

If the tire pressure indicator message is missing for longer than 5 seconds, the IPC sets DTC U0140:00 and flashes the TPMS warning indicator for approximately 75 seconds then illuminates the TPMS warning indicator.
