You should not have to give a second thought to these
acronyms, but it might be important to know what they stand for. The engine control management computer and
the powertrain control module are modern computers that receive inputs from
nearly every system on the vehicle. I
think we can safely say that is the HEART of the matter!
How does it all work?
Battery power is supplied to the ECM, or PCM, and the ECM is programmed
to send that electricity at a steady, regulated voltage to engine sensors, as
well as other control units, and other devices on the network. Every system in your Mercedes depends on the
information it receives to function properly.
Now the important question.
Whom do you trust to fix your Mercedes’ “heart”? The answer in the Denver area is always The
German Car Shoppe. We are Littleton and
Denver’s ECM and PCM repair experts. We
are known throughout the country as a top electrical repair shop for German
cars. Call for an appointment at our Littleton
