U1010 On Ford hybrids such as the Maverick Hybrid, U1010 is a manufacturer network code reported by dealers as invalid internal control module monitoring data received from the hybrid powertrain control module

Ford hybrid PCM invalid monitoring data

U1010 in short

On the Ford Maverick Hybrid, U1010 means invalid internal monitoring data was received from the hybrid powertrain control module. Owners report sudden loss of power on the highway and a car that shifts to neutral. Dealers cite a software update or a suspect module, so have a dealer diagnose it soon.

On the Maverick Hybrid, owners report a dealer readout of U1010, invalid internal control module monitoring data received from the hybrid powertrain control module, together with U1011 and a car that loses power or drops into neutral while driving. Reported dealer answers range from a software update to a suspect hybrid PCM.

Nissan service bulletin summaries also list U1010 with U1000 among communication codes stored in the engine control unit, but they do not say what U1010 means, so this page does not define it for Nissan.

This page speaks only for Ford; other makes may use U1010 differently.

Most likely causes

  1. Hybrid powertrain control module fault

    Supported by vehicle data
    Why it ranks here
    A 2022 Maverick Hybrid dealer said U1010 was present and the hybrid powertrain control module was suspected bad.
    What would change this
    Rises if U1010 returns after updates and clearing. Falls if an update stops the code.

  2. Software update needed

    Supported by vehicle data
    Why it ranks here
    Ford told one Maverick owner to check for updates, clear the codes and retest, and another owner saw the codes after recall 23E09 work.
    What would change this
    Rises if an update is available for the car. Falls if the code and power loss come back after updating.

What to test first

Start at step 1. Each result tells you what it means and where to go next.

  1. Read every stored code and note whether U1011 or other U1xxx codes come with U1010.

    • IfU1011 is stored too on a hybrid Maverick

      It meansThe hybrid control module data path is involved; a dealer should check for updates and test the module.

      Go to step 2

    • IfU1010 is the only code stored

      It meansAsk the dealer to check for open software updates and bulletins for your VIN.

  2. Ask the dealer to check for open software updates and bulletins for your VIN, then test the module power, ground and network.

    Warning:Hybrid and high-voltage systems are not a home repair; leave testing to a trained technician.

Symptoms

  • Sudden loss of drive power or shutdown on the highway Gets more serious: stop and have it checked.
  • Shifts to neutral with Service AdvanceTrac and other messages Gets more serious: stop and have it checked.
  • Check engine light with U1010 stored

How to fix

This is a safety-critical system, so we explain the code but don't give repair steps. Have it inspected by a qualified technician.

U1010 questions

Is it safe to drive a Maverick Hybrid with U1010?

Owners report sudden power loss on the highway with it, so treat it as inspect-soon and stop if power drops while driving. We have not verified how widespread it is.
