5. ACTIVE TEST
HINT:
Performing the ACTIVE TEST using the hand
− held tester allows the relay, VSV, actuator and so on to oper-
ate without parts removal. Performing the ACTIVE TEST as the first step of troubleshooting is one of the
methods to shorten the labor time.
It is possible to display the DATA LIST during the ACTIVE TEST.
(a)
Warm up the engine.
(b) Turn the ignition switch off.
(c) Connect the hand − held tester to the DLC3.
(d) Turn the ignition switch to the ON position.
(e) Push the ”ON” button of the the hand − held tester.
(f) Select the item ”DIAGNOSIS/ENHANCED OBD II/ACTIVE TEST”.
(g) According to the display on tester, perform the ”ACTIVE TEST”.

6. 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.
