Motor Vehicles >> Inspection and Maintenance (I/M) Program >> Can Certification Status

CAN Implementation Date Established

The state has established July 1, 2005 as the mandatory date when CAN hardware/software must be installed on analyzers certified for the North Carolina emissions program. Analyzers that do not meet this July 1 date will be locked out from performing any inspections until they meet this requirement. Until July 1, 2005, inspector-mechanics that are inspecting CAN-ready vehicles will continue to receive the prompt: "If this car cannot communicate, ABORT this OBDII inspection and perform a Safety-Only inspection".

State-Approved CAN Software

Beginning with model year 2003 automobile manufacturers are phasing in a new vehicle communication protocol called CAN (Controller Area Network). By model year 2008 all vehicles will be using this new protocol. This new protocol will provide the auto manufacturers a higher degree of system and configuration flexibility, which includes the On-Board Diagnostic II (OBD2) system. CAN will allow more information to be processed in a shorter period of time resulting in better error-handling capabilities.

The analyzers listed below have all been certified to perform OBD2 inspection on 1996 and newer vehicles. However, all the analyzers must be upgrade with CAN hardware/software before these analyzers can communicate with CAN-ready vehicles.

Certification Status (mm/dd/yy)

Acceptance Testing: The date a prototype unit has been received by the State and is being evaluated by conducting an extensive set of simulated inspections.
Beta Testing: The date when a limited number of production units has been approved for a 20-day field test.
Certified: Date granted for unlimited installation

Type of Analyzer

"Upgraded BAR-97" is a BAR-97 analyzer that has been upgraded with hardware and software to perform OBD2 testing. This machine also performs safety inspections and idle testing.
"Standalone OBD2" is a new machine that performs only safety inspections and OBD2 inspections (no idle testing).
BAR-90 units cannot be upgraded to perform OBD2 inspections. They may continue to be used for safety inspections and for idle testing.
