Dakota Digital BIM-01-2 User manual

[1] MAN #650500G
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.

Display data usage
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
The RPM, speed, and engine temperature data can each be used in place of individual connections to the instrument
control unit. These are individually selectable in the instrument system setup menus.
The automatic transmission gear position will be displayed in the message center if it is available. This will automatically
be displayed whenever the gear changes via shift selector, including manual mode if applicable. If a GSS-series universal
gear position sender is connected, the GSS will override the BIM-01-2 data.
The malfunction indicator lamp (MIL) or service engine soon indicator will be activated from the data bus when there is an
engine code set. This will not turn on the indicator for a lamp test function when the key is on, but the engine is not
running. This indicator can be enabled or disabled in the BIM-01-2 setup.
Some features require a minimum instrument system software revision (or higher) to be supported:
Engine Indicator Oil Pressure & Fuel Level
VHX VX03 VX04
VFD3 SE45 SE47
VFD3X SE54 SE55
The intake air temp, transmission temp, and ambient air temp will be displayed in the message center.
Display Setup
Setting up the display system will configure the instrument control box to read each input from either the terminals or
through the BIM cable from the Bus Interface Module.
The BIM menu of the display will not find the BIM-01-2, unless Boost is enabled for boosted 2009+ GM applications.
The following settings are for the basic information to be displayed with data from the BIM module.
Extra data that might be sent such as Intake Air Temp or Transmission Temp, can be brought up in the message centers
of the VFD3 and VHX system by toggling SW2 in normal operation of the vehicle. Similar data that might be present will
not automatically be shown in the HDX and RTX systems. That extra information must be placed in a group screen of
your choice, in the HDX and RTX setup.

VFD3 / VFD3X Setup:
Entering the VFD3 setup is done by holding SW1 (I) and turning the ignition to “on”, or “acc”.
Once in setup, one can move between speed, tach, volt, water, etc…. by tapping SW1 (I)
If you are setting multiple items, once done with one section you will automatically move onto the next item.
Obtaining speed from the BIM-01-2
•Hold the SW1 switch from the instrument system control box while turning the key on.
oThe speed display will show  and the message display will show SETUP.
•Release SW1. The displays should show and SPEED, respectively.
•Press and hold SW1 for at least 3 seconds, until  changes to “-”. The message display will show SENDER.
•Press and hold SW1 for at least 3 seconds, until  changes to “-”. The speed display will show the current
setting.
•Tap SW1 until  and BUS are displayed.
•Press and hold SW1 until  and DONE are displayed.
oNOTE: The AUTO, auto calibration, is removed.
oSpeed can only be fine-tuned with the ADJUST mode at a standstill.
oADJUST now only alters the percentage of speed by +/- 25%.
▪Drive a known speed and calculate how far off the speed is in percentage.
•GPS speed / displayed speed x 100
•Sample - [60/50=1.2] [1.2x100 = 120] 120%
▪Enter setup and go to ADJUST, tap SW1 to increment from 100% up to 125%.
▪After 125% the values will fall back to 75% and increment up again.
▪When the desired percentage is reached, hold SW1 until  changes to “-”.
•Tap SW1 until  and DONE are displayed.
•Press and hold SW1 until “-”and DONE are display.
