BLCKTEC 420 Display Functions

I/M Monitor Status - Identifies the I/M Monitor status area.
Monitor icons - Indicates which Monitors are supported by the vehicle under test, and whether or not the associated Monitor completed its diagnostic testing (Monitor status). When a Monitor icon is solid green, it indicates that the associated Monitor completed its diagnostic testing. When a Monitor icon is flashing red, it means that the vehicle supports the associated Monitor, but the Monitor is 'Incomplete' – the monitor has not completed its diagnostic testing routine.
Vehicle icon - Indicates whether or not the Diagnostic Tool is being properly powered through the vehicle’s Data Link Connector (DLC). A visible icon indicates that the Diagnostic Tool is being powered through the vehicle’s DLC connector.
Link icon - Indicates whether or not the Diagnostic Tool is communicating (linked) with the vehicle’s onboard computers. When visible, the Diagnostic Tool is communicating with the computers. If the Link icon is not visible, the Diagnostic Tool is not communicating with the vehicle’s computers.
Computer Icon - When visible, indicates the Scan Tool is successfully linked to a personal computer.
DTC Display Area - Displays the Diagnostic Trouble Code (DTC) number. Each fault is assigned a code number that is specific to that fault.
Code Type - Indicates the type of code being displayed: Stored, Pending, Permanent, etc.
Code Number Sequence - The Diagnostic Tool assigns a sequence number to each DTC that is present in the computer’s memory, starting with '1.' This number indicates which code is currently displayed. Code number '1' is always the highest priority code and the one for which 'Freeze Frame' data has been stored.
Code Enumerator - Indicates the total number of codes retrieved from the vehicle’s computer.
Test Data Display Area - Displays DTC definitions, Freeze Frame data, and other pertinent test information messages.
DTC Severity - Indicates the level of severity for the priority code (code number '1'), as follows:
Severity 1: This fault typically does not cause damage to components and should be serviced when convenient.
Severity 2: This fault may pose damage to components and should be repaired as soon as possible.
Severity 3: This fault will cause damage to components and should be repaired immediately.
Bluetooth icon - Indicates communication status with a compatible BLCKTEC mobile application. When ON, indicates an active Bluetooth connection has been established. When OFF, indicates Bluetooth is not connected.
MIL icon - Indicates the status of the Malfunction Indicator Lamp (MIL). The MIL icon is visible only when a DTC has commanded the MIL on the vehicle’s dashboard to light.
FREEZE FRAME icon - Indicates that 'Freeze Frame' data has been stored in the vehicle’s computer for the currently displayed DTC.

Note: The I/M Monitor Status icons are associated with INSPECTION and MAINTENANCE (I/M) READINESS STATUS. Some states require that all vehicle Monitors ran and completed their diagnostic testing before a vehicle can be tested for Emissions (Smog Check). A maximum of fifteen Monitors are used on OBD2 systems. Not all vehicles support all fifteen Monitors. When the Diagnostic Tool is linked to a vehicle, only the icons for Monitors that are supported by the vehicle under test are visible on the display.

Note: If '1' is a 'Pending' code, there may or may not be 'Freeze Frame' data stored in memory.
