There are a number of misconceptions involved in this thread. One is that CAN has something to do with OBDII. As it turns out MB doesn't use CAN for OBDII till the 211 chassis in 2003/4. It nevert was used for 220 or 210 or 203 (unless posibly after the facelift in 2005).

MB has used CAN for module communications since 1992 but that plays absolutely no part of this discussion as none of the tools discussed can talk MB, they onlky talk OBDII. OBDII will never talk to any module on a MB in MB. It only talks to the engine or in early cars the diagnostic module in the generic language that basically is like viewing a painting through wax paper. From the first OBDII cars and even the OBDI ones there have been 15 to 70 modules involved with systems on the cars. What you get with OBDII is little better than flash codes of ONE module (the one containing the OBDII protocols, not even the engine module on HFM cars).

What you get with a OBDII device is like looking at the system through wax paper and only getting ONE system. You are not going to see EA/CC/ISC or ETC, or ESM, or HFM, or, LH, or AB, ABS, ASR, ACC, IC, DCM, EIS, OVM, PSE, SAM, RCL, RST, CL, etc, etc, etc, etc and so on.

Just so no one gets any false ideas.
