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