Operations Global OBD-2/EOBD
Figure 7-1 Sample readiness status report
There are two types of monitored systems:
• Continuously monitored systems—those that impact vehicle emissions, and are required to
be monitored by OBD regulations.
• Non-continuously monitored systems—those that do not directly impact vehicle emissions,
and are required to be monitored by OBD regulations.
7.1.2 Current Data
Designated OBD Mode $01, this selection displays the current emission related data from the
selected electronic control module (ECM) of the vehicle. Displayed data includes analog inputs
and outputs, digital inputs and outputs, and system status information broadcast on the vehicle
data stream.

Data can be displayed in either text view or graph view. Press N to open the exit menu and select
Text/Graph to switch views.
7.1.3 Freeze Frame Data
Designated OBD Mode $02, this selection displays freeze fame data for any stored emission
related diagnostic trouble codes (DTC). Only one set of freeze frame data is retained in ECM
memory. In most cases the stored frame is the last DTC that occurred. Certain DTCs, those that
have a greater impact on vehicle emission, have a higher priority. In these cases, the highest
priority DTC is the one for which the freeze frame records are retained.
