This option presents a quick way to check for DTCs, isolate the cause of the
illuminated Malfunction Indicator Lamp (MIL), check monitor status prior to
emissions certification testing, verify repairs, and perform a number of other
services that are emission-related.
After the tool is properly connected to the vehicle’s DLC, tap “OBD II” in the
Job Menu. The tool will automatically start a check of the vehicle’s computer
to determine which type of communication protocol it is using. When the tool
identifies the computer’s communication protocol, a communication link is
established and then the screen will display the Monitor Status.
Tap “OK” to enter the diagnostic test modes selection screen.
