Outer Limits 4x4 Board

Hey guys.

Hopefully a super simple one.
Can one of you guys tell me what it means when there is an amber "SUB TANK" light on my GU wagon dash?
Is this a filter? Or pump issue?
Just it has never had this light on before....... maybe it should have?

Anyway can any of you guys give me a answer on what it actually indicates?

Thanks

Danny

Thats telling you there is somthing wrong. Check fuses if they are ok disconnect the battery for a couple of minutes & see if it fixes it. You can get codes out of the sub tank system but you will need the workshop manual for that.
