Checking the ignition spark

1. Remove the ECM cover.
2. Remove the ignition coils.
NOTE:
To prevent the engine from starting when
cranking it, be sure to remove all of the igni-
tion coils or disconnect all of the injector cou-
plers.
3. Connect an ignition coil assembly to the
special service tool.
Ignition tester: 90890-06754
4. Crank the engine and check the spark. If
the spark is weak, check the ignition sys-
tem.
WARNING
• Do not touch any of the connections of
the special service tool.
• Be sure to install the special service tool
to the ignition coil so that sparks do not
leak out.
• Keep flammable gas or liquids away,
since this test can produce sparks.
NOTE:
The ignition spark can also be checked using
the "Stationary test" of the YDIS.
