How to read ATTESA fault codes in a Nissan Skyline GT-R

Nissan Skyline GT-R, ATTESA all wheel drive system fault codes 18 and 19.

ATTESA information

When I have seen a code 18 recently - 2018, to 2019 it was not actually the pressure switch. Rather the pressure switch code was an indicator of low pressure in the nitrogen accumulator. The accumulator helps provide system pressure.

If the accumulator pressure is low, normally the ATTESA pump runs a little longer than normal prime on startup. The next indicator would be a clicking sound from the ATTESA relay in the trunk. You will hear it click, click, click, click. This is also a good indication of the Accumulator pressure being low.
