96 C280 and Snap-On MT2500 Communication Problem
Hi,
Have MTG2500 (ver 6) (MT2500 Graphing Model), with MB-1 cable and S-20 key, with 2.4 (2001) Mercedes primary cartridge using 38 pin under hood connector on 96 C280. Three modules are listed in the scanner menu. DM, HFM, EGS Scanner connects right away to the DM module and properly reports codes and data, but does not appear to connect with HFM, and reports communication failure when trying to communicate with the EGS transmission modules. When attempting communication with the HFM module it just reports "Initializing Communication, Please Wait". I have waited 7 min or more several times and it still does not establish communication nor does it give a failed communication message. Different when trying to connect to the transmission module, then it does report failed communication within 1 min. The unit does not appear to be locked up when attempting to communication with the HFM module and I have carefully followed the connection/ ignition switch on procedure. Could this be a personality key problem? Do they often fail? Am I waiting long enough, > 7 min for the connection to the HFM. Should I try disconnecting the battery to reset the ECU? This is a popular scanner any other help is most appreciated. Thanks Martineau Edit/Delete Message
