Error codes on S500 A/C Display Unit

I know this will probably seem like a REALLY stupid question.... But.... In the past I remember finding a thread that showed me how to bring up error codes on my A/C (heating/cooling) display screen, and I used this process to 'reset' the computer so that that my A/C could be activated (via that button on the unit) but I forgot how to bring it up so I can check them.

I have a 2002 s500 and would like to bring up the codes, could you tell me the correct buttons I need to push and what the definitions of the codes are?

I have been searching thru the sites I have membership with but cannot find the threads I used to reference this in the past.

Hold the rest button until the display changes.

The above procedure will pull up the actual value screens.

Read part 2 to pull up error codes. http://www.eclassbenz.com/node/27
