Term	Definition
Monitor description	Description of what the TCM monitors and how it detects malfunctions (monitoring purpose and its details).
Related DTCs	Group of diagnostic trouble codes that are output by the TCM based on the same malfunction detection logic.
Typical enabling condition	Preconditions that allow the TCM to detect malfunctions. With all preconditions satisfied, the TCM stores the DTC when the monitored value(s) exceeds the malfunction threshold(s).
Sequence of operation	The priority order that is applied to monitoring if multiple sensors and components are used to detect the malfunction. While a sensor is being monitored, the next sensor or component will not be monitored until the previous monitoring has concluded.
Required sensor/components	The sensors and components that are used by the TCM to detect malfunctions.
Frequency of operation	The number of times that the TCM checks for malfunctions per driving cycle. "Once per driving cycle" means that the TCM detects the malfunction only one time during a single driving cycle. "Continuous" means that the TCM detects the malfunction every time the enabling condition is met.
Duration	The minimum time that the TCM must detect a continuous deviation in the monitored value(s) before storing a DTC. This begins after the "typical enabling conditions" are met.
Malfunction thresholds	Beyond this value, the TCM will conclude that there is a malfunction and store a DTC.
MIL operation	MIL illumination timing after a defect is detected. "Immediate" means that the TCM illuminates the MIL the instant the TCM determines that there is a malfunction. "2 driving cycles" means that the TCM illuminates the MIL if the same malfunction is detected again in the 2nd driving cycle.
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 whether a sensor or solenoid is defective or not.
