COMPRESSION PRESSURE
InspectionINFOID:0000000005398044
1. Warm up engine thoroughly. Then, stop it.
2. Release fuel pressure. Refer to
EC-496, "
Inspection".
3. Remove ignition coil and spark plug from each cylinder. Refer to EM-46, "
Exploded View".
4. Connect an engine tachometer (not required in use of CONSULT-III).
5. Install a compression tester (B) with an adapter (commercial service tool) (A) onto spark plug hole.
• Use the adapter whose picking up end inserted to spark plughole is smaller than 20 mm (0.79 in) in diameter. Otherwise, it
may be caught by cylinder head during removal.
6. With accelerator pedal fully depressed, turn ignition switch to “START” for cranking. When the gauge pointer stabilizes, read the compression pressure and the engine rpm. Perform these steps to check each
cylinder.
CAUTION:
Always use fully a charged battery to obtain the specified engine speed.
• If the engine speed is out of the specified range, check battery liquid for proper gravity. Check engine speed again with normal battery gravity.
• If compression pressure is below minimum value, check valve clearances and parts associated with combustion chamber (Valve, valve seat, piston, pi ston ring, cylinder bore, cylinder head, cylinder head
gasket). After the checking, measure the compression pressure again.
• If some cylinder has low compression pressure, pour small amount of engine oil into the spark plug hole
of the cylinder to re-check it for compression.
- If the added engine oil improves the compression, piston rings may be worn out or damaged. Check pis-
ton rings and replace if necessary.
- If the compression pressure remains at low level despite the addition of engine oil, valves may be mal- functioning. Check valves for damage. Replace valve or valve seat accordingly.
• If two adjacent cylinders have respectively low compression pressure and their compression remains low even after the addition of engine oil, cylinder head gasket is leaking. In such a case, replace cylinder
head gasket.
7. After inspection is completed, install removed parts.
8. Start the engine, and confirm that the engine runs smoothly.
9. Perform trouble diagnosis. If DTC appears, erase it. Refer to EC-106, "
Description".

CHECKING COMPRESSION PRESSURE
1. Warm up engine thoroughly. Then, stop it.
2. Release fuel pressure. Refer to
EC-582, "
Fuel Pressure Check".
3. Disconnect fuel pump fuse (1) to avoid fuel injection during mea- surement.
4. Remove engine room cover.
5. Remove ignition coil and spark plug from each cylinder. Refer to EM-149
.
6. Connect an engine tachometer (not required in use of CONSULT-III).
7. Install a suitable compression tester (B) with an adapter (A) onto spark plug hole.
• Use the adapter whose picking up end inserted to spark plughole is smaller than 20 mm (0.79 in) in diameter. Otherwise, it
may be caught by cylinder head during removal.
8. With accelerator pedal fully depressed, turn ignition switch to “START” for cranking. When the gauge pointer stabilizes, read the compression pressure and the engine rpm. Perform these steps to check each
cylinder.
Compression pressure:
Unit: kPa (bar, kg/cm2 psi) /rpm
CAUTION:
Always use a fully charged battery to obtain the specified engine speed.

GENERAL MAINTENANCE
UNDER THE HOOD AND VEHICLE
The maintenance items listed here should be checked periodically (e.g. each time you check the engine oil or refuel).
Seat beltsCheck that all parts of the seat belt system (e.g. buckles, anchors, adjusters and
retractors) operate properly and smoothly and are installed securely. Check the
belt webbing for cuts, fraying, wear or damage. MA-48
Accelerator pedal
Check the pedal for smooth operation and make sure the pedal does not catch
or require uneven effort. Keep the floor mats away from the pedal. —
Clutch pedal Make sure the pedal operates smoothly and check that it has the proper free play. CL-6
BrakesCheck that the brake does not pull the vehicle to one side when applied. —
Brake pedal and
booster Check the pedal for smooth operation and make sure it has the proper distance
under it when depressed fully. Check the brake booster function. Be sure to keep
floor mats away from the pedal. BR-6
and
BR-20
Parking brake Check that the lever has the proper travel and make sure that the vehicle is held
securely on a fairly steep hill when only the parking brake is applied. PB-5
Automatic transaxle
“Park” mechanismCheck that the lock release button on the selector lever operates properly and
smoothly. On a fairly steep hill check that the vehicle is held securely with the se-
lector lever in the “P” position without applying any brakes. —
CVT P (Park) position
mechanism On a fairly steep hill check that the vehicle is held securely with the selector lever
in the “P” position without applying any brakes.

A/C condenser,
radiator and hos-
es Check the front of the condenser and radiator and clean off any dirt, insects, leaves,
etc., that may have accumulated. Make sure the radiator hoses have no cracks, de-
formation, deterioration or loose connections.
—
Brake and clutch
fluid levels Make sure that the brake and clutch fluid levels are between the “MAX” and “MIN”
lines on the reservoirs.
BR-9
Battery
Check the fluid level in each cell. It should be between the “MAX” and “MIN” lines.
Vehicles operated in high temperatures or under severe conditions require frequent
checks of the battery fluid level. —
Engine drive belts Make sure that no belt is frayed, worn, cracked or oily. EM-14

Exhaust system
Make sure there are no loose supports, cracks or holes. If the sound of the exhaust
seems unusual or there is a smell of exhaust fumes, immediately locate the trouble
and correct it. MA-37, "EXHAUST SYS-
TEM : Checking Exhaust
System HR16DE", MA-38,
"EXHAUST SYSTEM :
Checking Exhaust System
MR18DE"
Underbody
The underbody is frequently exposed to corrosive substances such as those used
on icy roads or to control dust. It is very important to remove these substances, oth-
erwise rust will form on the floor pan, frame, fuel lines and around the exhaust sys-
tem. At the end of winter, the underbody should be thoroughly flushed with plain
water, being careful to clean those areas where mud and dirt can easily accumu-
late. —
Fluid leaks Check under the vehicle for fuel, oil, water or other fluid leaks after the vehicle has
been parked for a while. Water dripping from the air conditioner after use is normal.
If you should notice any leaks or gasoline fumes are evident, check for the cause
and correct it immediately. —
