Hi mate, the sub tank issue is often caused by a poor earth to the tank pump, or other accessories like spot lights earthed to the chassis but not earthed back to the body and battery. This confuses the pump check circuit and it goes into error bringing on the light.
To cancel the light and reset, you disconnect the battery for ten min or more. It should go out then work normally again, but if it doesn't then start looking at the earthing.
