Automatic Transaxle System (For Sedan) -- Definition Of Terms

Term	Definition
Monitor description	Description of what the ECM monitors and how it detects malfunctions (monitoring purpose and its details).
Related DTCs	A group of diagnostic trouble codes that are output by the ECM based on the same malfunction detection logic.
Typical enabling conditions	Preconditions that allow the ECM to detect malfunctions. With all preconditions satisfied, the ECM sets 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 one sensor is being monitored, the next sensor or component is not monitored until the current monitoring is concluded.
Required sensor/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 malfunctions only one time during a single driving cycle. "Continuous" means that the ECM detects malfunctions every time the enabling conditions are met.
Duration	The minimum time that the ECM must sense a continuous deviation in the monitored value(s) before setting a DTC. This timing begins when the typical enabling conditions are met.
Malfunction thresholds	Beyond this value, the ECM concludes that there is a malfunction and sets a DTC.
MIL operation	MIL illumination timing after a defect is detected. "Immediate" means that the ECM illuminates the MIL the instant the ECM determines that there is a malfunction. "2 driving cycle" means that the ECM illuminates the MIL if the same malfunction is detected again in the next driving cycle.
Component operating range	Normal operating ranges of sensors and solenoids under normal driving conditions. Use these ranges as references. They cannot be used to judge if a sensor or solenoid is defective or not.
