HINT:
*: When cranking the engine, each cylinder
measures the engine rpm.
In this ACTIVE TEST, the fuel and ignition of all
cylinders are cut, and cranking occurs for
approximately 10 seconds. Then, each cylinder
measures the engine rpm. If a cylinder's engine rpm
is higher than the others, that cylinder's
compression pressure is compared to the others,
and is determined whether it is low or not.
1. Warm up the engine.
2. Turn the ignition switch off.
3. Connect the intelligent tester to the DLC3.
4. Turn the ignition switch ON and turn the

intelligent tester on.

5. Select the following menu items: DIAGNOSIS /

ENHANCED OBD II / ACTIVE TEST /
COMPRESS CHECK.
HINT:
If the results are not displayed normally, select
the display items from the DATA LIST before
performing the ACTIVE TEST. Select the
following menu items: DIAGNOSIS /
ENHANCED OBD II / DATA LIST / USER DATA /
ENG SPEED #1, ENG SPEED #2, ENG SPEED
#3, ENG SPEED #4, ENG SPEED #5, ENG
SPEED #6 (Press the YES button to change the
ENG SPEED #1 to #6) and then press the
ENTER button.

6. While the engine is not running, press the RIGHT

or LEFT button to change the COMPRESS
CHECK to ON.
HINT:
After performing the above procedure, the
ACTIVE TEST's COMPRESS CHECK will start.
Fuel injection for all cylinders is prohibited, and
each cylinder's engine rpm measurement will
enter standby mode.

7. Fully open the throttle.
8. Crank the engine for about 10 seconds.
9. Monitor the engine speed (ENG SPEED #1 to

#6) displayed on the tester.
HINT:
At first, the tester's display will show each
cylinder's engine rpm measurement to be
extremely high. After approximately 10 seconds
of engine cranking, each cylinder's engine rpm
measurement will change to the actual engine
rpm.
NOTICE:
•

After the ACTIVE TEST's COMPRESS
CHECK is turned ON, it will automatically
turn off after 255 seconds.

•

When the COMPRESS CHECK test is OFF
and the engine is cranked, the engine will
start.

•

If the COMPRESS CHECK test needs to be
performed after it is turned ON and
performed once, press EXIT to return to
the ACTIVE TEST menu screen. Then
perform the COMPRESS CHECK test
again.

•

Use a fully-charged battery.

SYSTEM CHECK
HINT:
Performing a SYSTEM CHECK enables the system,
which consists of multiple actuators, to be operated
without removing any parts. In addition, it can show
whether or not any DTCs are set, and can detect
potential malfunctions in the system. The SYSTEM
CHECK can be performed with an intelligent tester.
(a) Connect an intelligent tester to the DLC3.
(b) Turn the ignition switch ON.
(c) Turn the tester ON.
(d) Select the following menu items: DIAGNOSIS /

ENHANCED OBD II / SYSTEM CHECK.

(e) Perform the SYSTEM CHECK by referring to the

table below.
