fore, some detailed areas may not be shown exactly the same as on the actual vehicle.
1. Enter diagnostic mode (see page 05-1784).
2. Select ºDisplay Checkº from the ºDiagnosis MENUº
screen.
3. Select ºVehicle Signal Checkº from the ºDisplay
Checkº screen.
4. When the ºVehicle Signal Check Modeº screen is dis-

DEFINITION OF TERMS
TermDefinition
Monitor descriptionDescription of what the ECM monitors and how it detects malfunctions (monitoring purpose and its details).
Related DTCsA 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 current sensor
monitoring is finished.
Required sensor/compo-
nentsThe 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.
ºOnce per driving cycleº means that the ECM detects the malfunction only one time during a single driving cycle.
ºContinuousº means that the ECM detects the malfunction every time an enabling condition is met.
DurationThe minimum time that the ECM must sense a continuous deviation in the monitored value(s) before setting a
DTC. This timing begins after the ºtypical enabling conditionsº are met.
Malfunction thresholdsBeyond 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.
ºImmediateº means that the ECM illuminates the MIL the instant the ECM determines that there is a malfunction.
º2 driving cyclesº means that the ECM illuminates the MIL if the same malfunction is detected again in the 2nd
driving cycle.
