Hi,
I have a 2004 Mercedes S500 (Japanese Spec) with a transmission (7-speed 722.9) that is in limp mode (not shifting). Does anyone know if the Maxisys MS906BT is capable of reading the TCM on this vehicle? I ask because I am unable to connect to the TCM, though all the other modules are accessible.
So is it a limitation on the diagnostic tool, or is the TCM most likely the culprit here (wiring has been checked & is in order). Appreciate any input on this. Thanks.
