Data Recovery Blf<k>j;ao, the DCJ OBD2 scantool, and Controller Area Network (buss), which requires the StarsCan scantool - CAN is a local communications intranet used throughout industry for measurement and control of various system functions, usually with microprocessor-based devices - in the KJ CRD the Bosch Engine Control Module handles the Diesel engine, the Transmission Control Module handles the 545RFE transmission, the Body Control Module handles the instrumentation, lighting, and HVAC, the Antilock Brake Module handles the stopping, the SKIM and SKREEM modules handle security, the module in the right front door jam handles the radio comm for tire pressures, the EVIC allows brief glimpses into that world - and, they all talk amongst each other on various priority-determined levels - the language is universal, consisting of poll, command, and response, with each microprocessor device having a specific address on the buss, some having several addresses, depending on function - usually there is one master controller, with the rest being intelligent slaves, each doing it's own thing autonomously, but required to respond to the Master - it's a priority-based system, running at 10\100kb\s and 500kb\s in the KJ
The other techie word\numbers mentioned are other levels of communication, more primitive, slower and simpler, for the normal OBD2 stuff
