Special Notes
- This Fault Code can be stored in Relation to Remote Control or Immobilizer Problems. For most Models these systems are separated and should therefor also be diagnosed separately.

Even if the Immobilizer engages, the Engine will still start fine but cut out after 2-3 Seconds. If you are NOT experiencing this behavior (e.g. Engine doesn't start at all) your Problem is very likely NOT Immobilizer related.
