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.
