2) Compression Pressure Test
Standard Service Data ▶
A9912 0012B (001 589 76 21 00) Compression Pressure Tester -
Measuring Procedure ▶
Warm the engine up to normal operating temperature.
Remove the spark plugs using the spark plug wrench.
Place the diagram sheet to compression pressure tester A9912 0012B (001 589 76 21 00).
Connect the adaptor to compression pressure tester A9912 0012B (001 589 76 21 00) and
install it into the spark plug hole.
Crank the engine approx. eight revolutions by using the start motor.
Compare the measurements of compression pressure tester A9912 0012B (001 589 76 21 00)
with the specifications.
Measure the compression pressure of the other cylinders in the same way.
If measured value is not within the specifications, perform the cylinder pressure leakage test. -

3. CAPACITY AND NAME OF FUSE AND RELAY IN ENGINE
COMPARTMENT
The label attached on each fuse box
indicates only major fuses and
relays. Therefore, there are more
fuses and relays than indicated. For
details about the connection of fuses
and relays, refer to the power

The certification for the immobilizer is performed when turning the ignition switch to the "ON" position after
the CAN communication between the ECU and immobilizer is established.
