Internal Control Module Memory Check Sum Error

41 brands affected · Generic SAE J2012 description.

Key terms: Control module: a small computer that runs one part of the car · SAE J2012: the standard generic code list · Powertrain: engine, transmission and emissions

1What it means in plain English

The engine control module's internal memory check failed, so its stored settings cannot be trusted.

2Common causes

Internal engine control module fault
Low or unstable battery voltage
Power or ground connection problem
Water or corrosion damage to the module
Faulty software or calibration

3Can I drive?

Serious · drive with care

If the engine runs normally, drive carefully to a workshop for diagnosis. The fault can cause poor running or a no-start at any time; if it runs badly or will not start, have it towed.

This page gives general information. It is not professional advice. For a definite diagnosis and a repair quote, ask a qualified mechanic to inspect the car.
