Emergency Run Manager (EME) Fault Code Diagnosis – Hybrid Car Specialist UK

EME Fault Codes in Your Hybrid? We Diagnose and Fix It – UK-Wide

Emergency Run Manager (EME) faults are becoming increasingly common in modern hybrids. These error codes often indicate torque limitation, engine speed control issues, or a forced request to activate the combustion engine.

If you’ve seen codes like 21A11A, 235410, 21A005, or 21A124, your hybrid is alerting you to a deeper electronic management or powertrain control fault.

🔍 What Is the Emergency Run Manager (EME)?

The EME is a critical module that steps in when something compromises the hybrid system’s ability to run normally. It manages how and when the engine and electric motor work together in emergency scenarios—whether due to sensor failure, inverter faults, or safety concerns.

When fault codes are logged here, the vehicle might:

  • Enter limp mode

  • Limit torque or power delivery

  • Force the engine to stay on continuously

  • Disable the EV-only drive mode


🧾 Common EME Fault Codes We Diagnose

Here are some typical EME codes we’ve seen during mobile diagnostics:

  • 21A11A – Combustion engine startup request due to hybrid system safety issue

  • 235410 – Torque reduction due to unknown engine communication error

  • 21A005 – Emergency run mode active, power limitation engaged

  • 21A111 / 21A124 – High-voltage powertrain mismatch or battery fault

  • 21A003 – Temporary combustion engine override triggered by hybrid safety logic

These codes are manufacturer-specific, often seen on BMW, Mercedes, Toyota, Lexus, and other plug-in or series-parallel hybrid systems.
