ECM (DTCs Not Accessible)

WARNING: This page is about a different car, the 2002 Nissan Maxima and 2002 Infiniti I35. However, it is still accessible from the selected car via links, so may be relevant.

Maximum engine speed is 3000 RPM. Fuel injection operates in simultaneous mode. Ignition timing is fixed. Fuel pump relay remains on when engine is running and off when engine stalls. Cooling fans operate at high speed when engine is running. If ECM fail-safe mode is confirmed, replace ECM.
