Compression Check: Testing and Inspection
Check compression pressure on all four cylinders as follows:
1. Warm up engine.
2. Stop engine after warming up.
3. Disconnect couplers from both ignition coil assembles.
WARNING: Failure in disconnecting ignition coil coupler can cause spark to occur in engine room possibly resulting in a dangerous
explosion.
4. Remove all spark plugs and disconnect fuel injector wire harness at couplers.
5. Install special tool (Compression gauge) into spark plug hole.

(A): 09915-64510-001
(B): 09915-64510-002
(C): 09915-64530

6. Disengage clutch (to lighten starting load on engine) for M/T model, and depress accelerator pedal all the way to make throttle valve full-open.
7. Crank engine with fully charged battery, and read the highest pressure on compression gauge.
NOTE: For measuring compression pressure, crank engine at least 250 r/min. by using fully charged battery.
