BIM-01-2-J1939
Bus Interface Module for J1939 vehicles
This Bus Interface Module is designed to read engine information from the J1939 bus. The module is connected to the
J1939 Bus through CAN bus-adapter harness to the CANH (RED WIRE) and CANL (BLACK WIRE) on the main harness.
There are two interface (I/O) ports on the BIM-01-2-J1939 module. Either one can be connected to the instrument system
or to another module, allowing several units to be daisy chained together.
Cannot daisy chain with GPS-50-2.
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; as it should be mounted in the vehicle’s cabin.
The engine information that is available from the unit depends on the ECU programming and add-ons.
Readings this module monitors for: vehicle speed, engine RPM, engine coolant temperature, engine oil pressure,
engine light (MIL), intake/manifold air temperature, trans fluid temp, fuel level, ambient air temp, fuel pressure, air fuel
ratio, gear and boost.
The engine and transmission information that is available from the unit depends on your ECU and add-ons.
A GPS-50-2 CANNOT be linked (daisy chained) to a BIM-01-2-J1939 with a BIM cable.
The two units cannot talk to the display control box at the same time.

Display Setup
VFD and VHX system will add extra readings to the message displays under the tach.
HDX and RTX need a group screen configured to show additional information, such as Boost or Intake temp
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-J1939, but will find specific channels for Fuel Pressure, Oil Temp,
Boost and Air/Fuel Ratio.
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, Fuel Pressure, Air/Fuel Ratio or Boost, 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.
Display data usage
The following readings can each be used in place of dedicated sending units to the instrument system control box. These
are individually selectable in the display system instrument setup menus.
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-J1939
•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.

Quick tips:
While the BIM is operating, the dot in the upper left corner of the display will indicate the status:
•On steady indicates it is powered up but not receiving any BIM bus activity.
•Flashing indicates it is communicating on the BIM bus.
•A dot in the upper center indicates that there is an engine code set (MIL active).
•If the display shows “BUS”, then it is scanning to try and communicate with the vehicle bus but cannot get an
answer.
oThis could indicate that the ODBII connector is not wired properly
oThe BIM-01-2-J1939 is not compatible with the ECU
To see the sensor and channel status on the BIM display, press and hold the switch to cycle through the screens.
The screen will display the data that is available:
“”- Engine Oil Pressure
“” –Engine Coolant Temp
“” - Ambient Air Temp
“” - Intake Air Temp
“”- Gear Position
“”- Fuel Level Input
“”- Boost/Vacuum data
“”–Fuel Pressure
“”- RPM/Tachometer data
“”–Oil Temp
If you do not see any number of these listed it means it may not be transmitted for the BIM-01-2-J1939 to read.
Emissions note:
If your vehicle requires emissions testing in your area, the check engine feature of this unit cannot be used to operate the
Check Engine or Service Engine indicator.
