Diagnostic Trouble Codes (DTCs) are codes used to identify malfunctions in vehicles, provided by the vehicle’s electronic control unit(ECU). These codes flag issues with vehicles or equipment and help the shop to understand and diagnose problems.

Note: These will report for vehicles with TennaFLEET II (and TennaCAM 2.0) and TennaCANbus trackers.
