What is a VCM?

Vehicle Control Module (VCM)

The VCM Suite and this document use the term Vehicle Control Module (VCM) to mean the computer that is primarily responsible for engine and transmission operation. In some vehicles, there are actually two modules, an Engine Control Module (ECM) and a Transmission Control Module (TCM). In general, the number of modules required to be read or written will be transparent to the end user or become obvious during the read/write process.

In certain applications, VCM Editor supports configuring the following additional modules:

Fuel System Control Module (FSCM)
Fuel Injection Control Module (FICM)
Body Control module (BCM)

Most vehicles also contain many other modules that control different aspects of the vehicle's operation. At this time, VCM Suite does not allow modification of these other modules. Some examples are:

Anti-lock Braking System (ABS) module
Instrument Panel Cluster (IPC)
Active Handling module
Radio module
Heater, Ventilation and Air Conditioning (HVAC) module
Navigation system module
