There are actually 21 codes:

01 - Display Test
02 - Instantaneous fuel consumption in l/100 km
03 - Instantaneous fuel consumption in l/hr
04 - Average fuel consumption
05 - Current range
06 - Amps
07 - Fuel in tank as % of full
08 - Instantaneous speed
09 - Alternator voltage
10 - Speedometer correction factor
11 - Country setting for language
12 - Average speed
13 - Estimated time of arrival
14 - Software date of OBC
15 - Some sort of diagnostic information
16 - ?
17 - ?
18 - Single of two-tone horn selection
19 - Lock/unlock OBC functions
20 - Correction factor for OBC fuel consumption
21 - Reset all stored codes

Another neat trick is to hold the check control button down and turn the key to the ON position. This will display software version numbers and the VIN code on the message display and perform an instrument test which will light all the lamps and LEDs and cycle all the gauges (speedo to 120 km/h and rpms to 3500). Try it, it will really impress your friends.

I read somewhere (and verified it myself) that pushing the 1000 and 10 buttons simultaneously while the OBC is reading temp will get you to a menu and pressing the S/R button until you get to 09 makes the display read the voltage across the battery. So here's the 6 million dollar question. What do 01-08 test??? Any thoughts?
