8. ACTIVE TEST
HINT:
Performing the ACTIVE TEST using the hand-held tester or the OBD II scan tool allows the relay, VSV, ac-
tuator and so on to operate without parts removal. Performing the ACTIVE TEST as a first step of trouble-
shooting is one method to shorten diagnostic 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 or the OBD II scan tool to the DLC3.
(d) Turn the ignition switch ON.
(e) Push the ºONº button of the hand-held tester or the OBD II scan tool.
(f) Enter the following menus: DIAGNOSIS / ENHANCED OBD II / ACTIVE TEST.
(g) According to the display on tester, perform the ºACTIVE TESTº.
ItemTest DetailsDiagnostic Note
INJ VOL
[Test Details]
Control the injection volume.
Min.: -12.5%, Max.: 24.8%
[Vehicle Condition]
Engine speed: 3,000 rpm or less.All injectors are tested at
once.
Injection volume is gradual-
ly changed between -12.5
and 25%
A/F CONTROL
[Test Details]
Control injection volume
-12.5 or 25 % (change injection volume -12.5 % or 25 %)
[Vehicle Condition]
Engine speed: 3,000 rpm or less
Following A/F CONTROL
procedure enables techni-
cian to check and graph volt-
age outputs of both the A/F
sensor and heated oxygen
sensor
For displaying graph, enter
ºACTIVE TEST / A/F CON-
TROL / USER DATAº, select
