This Bus Interface Module has an input to read engine information from vehicles using the GM 1996-up OBD-II protocol,
Ford 1996-up OBD-II protocol, some Chrysler 2000-up OBD-II protocol, or CAN (SAE J1979) OBD-II protocol. CAN SAE
J1979 OBD-II is used on all vehicles 2008 and newer and some vehicles from 2004
– 2008. There are two interface (I/O)
ports on the module. Either one can be connected to the gauge system or to another module, allowing several units to be
daisy chained together. Do not connect the I/O port to anything other than a Dakota Digital control box or BIM. Do not
mount the module in the engine compartment; it should be mounted in interior of the vehicle.
The BIM-01-2
does not use one of the 16 available bus ID’s like other Dakota Digital BIM units do. Speed and RPM data
are transmitted and updated every 0.1 second. The remaining data is sent one at a time in sequence along with the
speed and RPM. As an example on the first update speed, RPM, and engine temp would be sent. On the next update
speed, RPM, and intake temp would be sent. This will continue with the other data that is available and then will start
over again with speed, RPM, and engine temp.
The engine and transmission information that is available from the unit depends on the year, make, model, and options of
the vehicle. Some of the possible values are: engine RPM, vehicle speed, engine coolant temperature, intake air
temperature, transmission fluid temperature, transmission gear position, vacuum/boost and ambient air temperature.
Data that should always be available: RPM, speed, engine temp, intake temp, engine indicator(MIL)
Data that is transmission dependent: Transmission temp, transmission gear position
Data that is body control/ECM dependent: ambient air temp, engine oil pressure, fuel level, vacuum/boost
