sub tank light in 2004 diesel patrol

i would check the earth wire on the fuel transfer pump.

Had a 2.8 GU for 10 years. Light staying on seemed to occur if sub-tank was left empty for some time. Remedy, disconnect battery for a few minutes and bingo.

Hope it works for you.

I had the same the problem with my first GU, it was the transfer pump. cost about $700 with labour! Try disconnecting the battery for a few minutes and check all your fuses before you try your Nissan dealer! Michael

It's common just disconnect the battery for few mins and then reconnect & all should be fine

try the battery disconnect first

Thank you from the bottom of my sub tank.
Disconnected battery for 10 mins reconnected it and all is FANTASTIC.
I was not looking forward to going to Nissan and an auto elect said would take half day to take out dash and reset the module.
Thank you all,
bruce.

This is common on patrols , earth problems with electrics. Fix is add extra earth from body to transmission /engine and clean earth from battery to body and motor.See patrol4x4forum.
