After departed Melbourne's Albert Park 11 days ago looking as sick as a parrot
The seven-times World Campion was forced to retire on lap 19 due to damage sustained on lap one.
But it was the fact Mercedes were woefully off the pace throughout the weekend.
That left both drivers and team principal Ross Brawn at a loss to understand where their car's end of pre-season testing form had disappeared to.
Ahead of this weekend's second grand prix of the year in Sepang,
Schumi said: "Naturally we have studied our issues and problems and made solutions available.
"But we have to figure out how much they fit and cure what we have seen because we've had no testing.
"It is only Friday that is available to us, to figure out whether all the modifications we have made after Australia are spot on or not.
"We will find out this weekend whether we have made a step forward because in Barcelona (in testing) the car was functioning, but in Australia I don't think we saw the real car."
