Modern vehicles have an array of computer modules distributed in a network across the vehicle.
These modules used for monitoring and controlling everything from passenger comfort systems to the vehicle’s most sensitive functions including brake and ABS. These computer modules are each in charge of a large number of circuits.
The network of modules must have properly functioning communication channels to share data, mode and state with the others on the segment/array.
DiagnosticBuddies can program most electronic components, ECU’s, and computer control modules for most makes of vehicles: PCM’s, BCM’s, TCM’s, immobilizer modules, switches, and instrument clusters.
Powertrain Control Module
The Powertrain Control Module (PCM) is in charge of the function of the engine and its accessory systems.
Once replaced the PCM requires programming and configuration by a trained technician.
Body Control Module
The Body Control Module (BCM) is in charge of many functions both within the cabin and electrical control of ancillary systems.
Once replaced the BCM requires programming and configuration by a trained technician.
