Integrating aftermarket gauges into your vehicle has never been easier thanks to the Dakota Digital Obd2 Interface Module, also known as the BIM-01-2. This innovative module bridges the gap between your car’s sophisticated computer system and your Dakota Digital instruments, allowing you to monitor crucial engine and transmission data with ease. For car enthusiasts and those looking to enhance their vehicle’s instrumentation, understanding the capabilities of the Dakota Digital OBD2 interface module is essential.
What is the Dakota Digital OBD2 Interface Module BIM-01-2?
The Dakota Digital BIM-01-2 OBD-II Interface Module is a plug-and-play device designed to extract data directly from your vehicle’s OBD-II diagnostic port. This port, standard on most modern vehicles, is the gateway to your car’s Engine Control Module (ECM) and Transmission Control Module (TCM). The BIM-01-2 intelligently deciphers the data transmitted through this port, converting it into a format readable by Dakota Digital instrument systems. Instead of relying on traditional sensors for every reading, this module taps into the wealth of information already being processed by your vehicle’s computer.
Key Features and Data Points Available
The primary function of the BIM-01-2 is to provide your Dakota Digital gauges with accurate and real-time data about your vehicle’s performance. The specific data points available depend on your vehicle’s make, model, and ECM capabilities, but generally, you can expect access to the following:
Universally Available Data (on most vehicles):
- Speedometer: Provides a precise digital speed reading directly from the ECM, ensuring accuracy and eliminating the need for mechanical speed sensors in many applications.
- Tachometer: Displays engine RPM (Revolutions Per Minute), crucial for performance monitoring and ensuring you’re operating within optimal engine parameters.
- Engine Temperature: Monitors coolant temperature, a vital indicator of engine health and preventing overheating.
- Check Engine Indicator: Passes through the “Check Engine” light status from your vehicle’s ECM, allowing you to see this critical warning on your Dakota Digital display.
Vehicle-Specific Data (availability varies):
Beyond the standard readings, the BIM-01-2 can potentially unlock access to a range of vehicle-specific data, enhancing your insight into your car’s operation. These may include:
- Intake Air Temperature: Measures the temperature of the air entering your engine, important for performance tuning and diagnosing intake issues.
- Transmission Temperature: Monitors the temperature of your transmission fluid, critical for preventing overheating and extending transmission life, especially in performance or towing applications.
- Ambient Air Temperature: Displays the outside air temperature.
- Gear Position: Indicates the current gear your automatic transmission is in. Note that this may not be available on all vehicles, particularly GM Connect & Cruise packages.
- Oil Pressure: Provides real-time oil pressure readings, a crucial indicator of engine lubrication health.
- Boost Pressure: For turbocharged or supercharged vehicles, this displays the manifold boost pressure.
It’s important to note that while the BIM-01-2 is designed to access these additional data points, Dakota Digital cannot guarantee their availability or accuracy. The presence and reliability of these readings are entirely dependent on your vehicle’s ECM, the sensors installed by the original manufacturer, and the specific OBD-II protocol implemented. Variations in factory and aftermarket ECMs mean that data availability can differ significantly between vehicles.
Compatibility and System Requirements
The Dakota Digital BIM-01-2 is engineered for broad compatibility, supporting both J1850 and CAN OBD-II protocols. Specifically, it is compatible with:
- SAE J1850 VPW
- SAE J1850 PWM
- ISO 15765 CAN (500k 11 bit identifiers) following the SAE J1979 PID protocol.
This covers a wide range of OBD-II compliant vehicles. The BIM-01-2 is designed to seamlessly integrate with Dakota Digital instrument systems that utilize a black plastic control module, including the GRFX, RTX, HDX, VHX, and VFD3 series.

For older Dakota Digital instrument systems with a 3.5mm headphone jack BIM input on the control box, a 394194 adaptor harness is required for compatibility. It’s crucial to understand that earlier instrument systems featuring an aluminum control module are not compatible with BIM connectivity.
Vehicle Compatibility Considerations
While the BIM-01-2 is designed to be broadly compatible, certain factors can affect its functionality:
- Data Availability Varies: As mentioned earlier, the availability of vehicle-specific data (Intake Temp, Transmission Temp, etc.) is contingent on your vehicle’s ECM and factory sensors.
- GM Connect & Cruise Packages: Vehicles equipped with GM Connect & Cruise packages typically do not transmit gear position data via OBD-II, meaning the BIM-01-2 will not be able to acquire this information in those applications.
If you have any concerns about the compatibility of the BIM-01-2 with your specific vehicle, it is highly recommended to contact Dakota Digital’s sales or technical support department before purchase. They can provide expert guidance and confirm compatibility for your peace of mind.
Enhance Your Dashboard with OBD-II Data
The Dakota Digital OBD2 Interface Module BIM-01-2 offers a streamlined and efficient way to integrate comprehensive vehicle data into your Dakota Digital instrument system. By tapping directly into your vehicle’s OBD-II port, it simplifies installation, reduces the need for numerous individual sensors, and provides a wealth of real-time information to enhance your driving experience and vehicle monitoring capabilities. Unlock the full potential of your Dakota Digital gauges and gain deeper insights into your vehicle’s performance with the BIM-01-2.
