• 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.
3. 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 the intelligent tester.
(a) Connect the 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.
