NOTE:
Faults can be stored during initialisation of the PCM if all plugs are not connected.
If a fault appears under Environmental Condition in combination with an unrealistic date, e.g. 7 Feb. 36, the fault was stored at a time at which there was not yet any satellite reception.
The faults are stored only during the phase after terminal 86 s has been disconnected.
