| Term | Definition |
|---|---|
| Monitor Description | Description of what the ECM monitors and how it detects malfunctions (monitoring purpose and details). |
| Typical Enabling Conditions | Preconditions that allow the ECM to detect malfunctions.
With all preconditions satisfied, the ECM stores a DTC when the monitored value(s) exceeds the malfunction threshold(s). |
| Required Sensors/Components | The sensors and components that are used by the ECM to detect malfunctions. |
| Frequency of Operation | The number of times that the ECM checks for malfunctions per driving cycle.
"Once per driving cycle" means that the ECM detects a malfunction only once during a single driving cycle. "Continuous" means that the ECM detects a malfunction every time the enabling conditions are met. |
| Duration | The minimum time for which the ECM must detect a continuous deviation in the monitored value(s) in order to store a DTC. Timing begins after the "typical enabling conditions" are met. |
| Typical Malfunction Thresholds | Value beyond which the ECM will determine that there is a malfunction and store a DTC. |
