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 condition
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 malfunc-
tion.
When a sensor is being monitored, the next sensor or component will not be monitored until the sensor monitoring
is finished.
Required sensor/compo-
nents
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 the malfunction only one time during a single driving cycle.
”Continuous” means that the ECM detects malfunction every time an enabling condition is 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 after the ”typical enabling conditions” are met.
Malfunction thresholds
Beyond this value, the ECM will conclude that there is a malfunction and set a DTC.
MIL operation
MIL illumination timing after a defect is detected.
”Immediately” means that the ECM illuminates MIL the instant the ECM determines that there is a malfunction.
”2 driving cycle” means that the ECM illuminates MIL if the same malfunction is detected again in the 2nd driving
cycle.
