California Air Resource Board (CARB) has approved HEM Data for their HD I/M program. DAWN CARB Inspector™ is a small, easily portable solution and quick to install. It is ideal for the roaming inspector or at a service site. Just attach the hardware to the vehicle network connector, turn on the engine, and open the smart phone app. Complete the test within 2 minutes. DAWN (Data Acquisition With Network) is the umbrella name for HEM Data’s products.
The California Heavy-Duty Inspection and Maintenance Program
The California Air Resources Board (CARB) has developed an inspection and maintenance (HD I/M) program to ensure that heavy-duty vehicle emission control systems function properly and that emissions remain low throughout their operating life. The HD I/M program applies to nearly all diesel and alternative fuel vehicles with a gross vehicle weight rating (GVWR) of over 14,000 pounds, including all out-of-state and out-of-country vehicles. Vehicles that are model year 2013 and newer diesel engines, and model year 2018 and newer alternative fuel engines, are required to submit OBD data. Data is acquired using the vehicle’s OBD system to determine whether a vehicle’s emission control systems are functioning properly.
Interested HD I/M personnel must successfully complete a free online training session from CARB. An approved tester will receive a Tester ID that is valid for 2 years. A Test ID is required to use CARB Inspector. See the details of the CARB I/M program.
Components of DAWN CARB Inspector
The DAWN CARB Inspector consists of three components
- CAN Mini Streamer™ hardware (dongle)
- iPad or iPhone
- DAWN CARB Inspector™ software
CAN Mini Streamer Hardware
HEM Data’s CAN Mini Streamer sends the vehicle data to the DAWN CARB Inspector app. The Mini Streamer hardware conveniently fits directly on the 9-pin J1939 connector. An adapter cable works for the 16-pin J1939 connector or a non-standard connector. Baud rates of 250k, 500k, and 1000k are automatically detected.
CAN Mini Streamer™
The Mini Streamer acquires both J1939 and J1979 data. Acquired data is transferred to the iPad or iPhone using WiFi, thereby providing a convenient wireless connection. The tester is not required to be in the vehicle during the short test.
CARB Inspector Software™
CARB Inspector is supported on both an iPad and iPhone. As the app receives the data from the Mini Streamer hardware using a WiFi connection, the app displays real-time information to the user as the test is progressing. CARB requires that the app have internet access to start the test so that the data is immediately forwarded to the CARB website. This will not allow the encrypted data to be stored on the IOS device or PC.
Currently, the app is approved by CARB for J1939 support. J1979 support is in process and should be approved shortly. Contact sales@hemdata.com for the latest update. The app is on the Apple App Store. To activate the app, a license needs to be purchased.
