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. |
Typical Malfunction Thresholds | Value beyond which the ECM will determine that there is a malfunction and stores a DTC. |
Component Operating Range | Normal operation range of sensors and solenoids under normal driving conditions. Use these ranges as a reference. They cannot be used to judge if a sensor or solenoid is defective or not. |
