tests that have run since the last time the electronic control module (ECM)
memory was cleared.
• Monitors Complete This Cycle—displays only the results of monitor tests that
ran during the current drive cycle, they reset when the ignition is switched off.
Readiness Monitors is used to check the status of the OBD-II/EOBD monitored
systems. Certain emission-related OBD-II/EOBD systems are self monitored by
running continuous or periodic tests. Test results (e.g. Test Complete, Test Not
Complete, Test Not Supported, etc.) are shown in the data viewer (Figure 7-3).
Functionality and toolbar options are similar to using the PID Display within
