🔌 Function

The ECU controls the HPDI engine-management system by processing sensor inputs and commanding ignition timing, injector operation, fuel delivery, idle control, warning strategy and engine-protection functions.

⚠️ Common Signs of Failure

  • No-start or hard-start condition after fuel, spark and sensor checks
  • No injector pulse or inconsistent injector command
  • No diagnostic communication with the ECU
  • Intermittent shutdown, limp mode or erratic running
  • Persistent ECU-related fault codes after wiring and sensor testing
  • Engine running rich, lean or unevenly with verified fuel pressure
  • Misfire or ignition timing faults isolated to ECU output control
