43 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 keep-alive memory lost power and its stored values were not saved properly.

2Common causes

  1. Weak or disconnected battery
  2. Blown module fuse
  3. Power or ground connection problem
  4. Internal engine control module fault
  5. Charging system fault

3Can I drive?

Caution · drive with care

Usually safe to drive, but the engine may need to relearn idle and mixture settings. If it runs badly, have it checked.
