Routine maintenance

Check of a compression

PERFORMANCE ORDER

Check compression pressure on all four cylinders as follows. Warm the engine. After a warming up stop the engine.

After a warming up of the engine put the gear shifting lever on "Neutral" (for the And/T models put the gear shifting lever in position "P"), both install the parking brake and block driving wheels.

Disconnect a cable of an accelerator (3) from a clip (4) (only for vehicles with the left wheel).

Disconnect ignition coil couplings. Remove coils of ignition (1). Remove all spark plugs (2). Disconnect wires of a fuel injector from the coupling (5).

(A): 09915-64510-001 (C): 09915-64510-002 (C): 09915-64530 (D): 09915-67010

Switch off coupling (to reduce initial load of the engine) for the M/T models, and press a pedal of management of supply of fuel against the stop completely to open a butterfly valve.

Start the engine with completely charged accumulator and read the maximum instrument of pressure on a kompressimetra.

To measure compression pressure, start the engine, at least, on 250 revolutions per minute, by means of completely charged accumulator.

Technical characteristics compression pressure

	Compression pressure
Normal	1400 kPa (14.0 ^kg/cm2, 199.0 ps)
Limit	1200 kPa (12.0 ^kg/cm2, 170.0 ps)
The maximum deviation between two cylinders	100 kPa (1.0 ^kg/cm2, 14.2 ps)

points 9 - 11

After check insert spark plugs (2) and coils of ignition (1).

Connect ignition coil couplings. Connect a cable of an accelerator (3) to a clip (4) (only for vehicles with the left wheel).
