Dakota Digital BIM-01-2 Quick Start Manual

BIM-01-2
Bus Interface Module for OBD-II vehicle interface
This Bus Interface Module has an input to read engine information from vehicles using the J1850 GM 1996-up OBD-II
protocol, Ford 1996-up OBD-II protocol, Chrysler 2004-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 instrument 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 the vehicle cabin.
The BIM-01-2 normally 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, on a dedicated bus to the display box processor. The remaining
data is sent one at a time in sequence along with the speed and RPM.
Some 2009 and newer GM engines offer boost data. If enabled, the boost data will try to default to ID Channel 9 in the
control box for the display.
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.
A GPS-50-2 CANNOT be linked (daisy chained) to a BIM-01-2 with a BIM cable.
The two units cannot talk to the display control box at the same time.
