Pinpoint Test BJ: The Engine Hours And Engine Idle Hours Display Is Inoperative

WARNING: This page is about a different car, the 2021 Ford F-150. However, it is still accessible from the selected car via links, so may be relevant.
  1. Normal Operation and Fault Conditions 

    See Engine Hours Display and Engine Idle Hours Display. REFER to: Message Center - System Operation and Component Description .

    If the engine rpm data message is missing or invalid for less than 5 seconds, the IPC defaults the engine hours and engine idle hours displays to the last display based on the last message received.

    If the vehicle speed message is missing or invalid for 5 seconds or longer, the IPC sets DTC U0100:00 and defaults the engine hours and engine idle hours to the last displayed value with no additional accumulation.

    Possible Sources 

    • Speedometer indication concern
    • Tachometer indication concern
    • IPC
