2. CHECK PEDAL FREE PLAY
(a) Stop the engine and depress the brake pedal several
times until there is no more vacuum left in the booster.
(b) Push in the pedal until the beginning of the resistance is
felt. Measure the distance, as shown.
Pedal free play: 1 - 6 mm (0.04 - 0.24 in.)
If incorrect, check the stop lamp switch assy clearance.
If the clearance is OK, then troubleshoot the brake system.
Stop lamp switch clearance:
0.5 - 2.5 mm (0.020 - 0.098 in.)
3. CHECK PEDAL RESERVE DISTANCE
(a) Release the parking brake pedal.
With engine running, depress the pedal and measure the
pedal reserve distance, as shown.
Pedal reserve distance from asphalt sheet at 490 N
(50 kgf, 110.2 lbf): More than 63 mm (2.48 in.)
If incorrect, troubleshoot the brake system.

ON-VEHICLE INSPECTION
1. INSPECT BRAKE BOOSTER
(a) Air tightness check.
(1) Start the engine and stop it after 1 or 2 minutes. De-
press the brake pedal several times slowly.
HINT:
If the pedal goes down farthest the 1st time, but gradually rises
after the 2nd or 3rd time, the booster is air tight.
(2) Depress the brake pedal while the engine is run-
ning, and stop the engine with the pedal depressed.
HINT:
If there is no change in the pedal reserve distance after holding
the pedal for 30 seconds, the booster is air tight.
(b) Operating check.
(1) Depress the brake pedal several times with the igni-
tion switch OFF and check that there is no change
in the pedal reserve distance.
(2) Depress the brake pedal and start the engine.
HINT:
If the pedal goes down slightly, operation is normal.
2. INSPECT VACUUM CHECK VALVE
(a) Check vacuum check valve.
(1) Slide the clip and disconnect the vacuum hose.
(2) Remove the vacuum check valve.
(3) Check that there is ventilation from the booster to
engine, and no ventilation from the engine to the
booster.
(4) If any fault is found, replace the vacuum check
valve.

specified.

When inspecting a belt which is used for over 5 min-
utes, apply the specification of ºUsed beltº.

When reinstalling a belt which is used for over 5 min-
utes, adjust its belt deflection and tension to the inter-
mediate value of each specification in ºUsed beltº.

The V- ribbed belt tension and deflection value
should be checked after 2 revolutions of engine
cranking.

When using a belt tension gauge, confirm the accura-
cy first by using a master gauge.

engine.

Turn OFF all electrical systems before connecting the
terminals.

Perform this inspection after the cooling fan motor is
turned OFF.
(2) Remove the V-bank cover.

that the engine speed returns to the idle speed.
(6) Disconnect terminals 13 (TC) and 4 (CG) of the
DLC3.
(7) Inspect the ignition timing at idle.
Ignition timing: 7 to 24 BTDC
(8) Confirm that the ignition timing advances when the
engine speed is increased.
(9) Remove the timing light.
8. INSPECT ENGINE IDLE SPEED
(a) Warm up the engine.
(b) When using the hand-held tester or OBD II scan tool:
(1) Connect the hand-held tester or OBD II scan tool to the DLC3.
(2) Enter DATA LIST MODE on the hand-held tester or OBD II scan tool.
Idle speed: 630 to 730 rpm
NOTICE:

When checking the idle speed, the transmission is in the neutral position.

Check the idle speed with the cooling fan OFF.

Switch OFF all accessories and air conditioning before connecting the hand-held tester or OBD
II scan tool.

9. INSPECT COMPRESSION
(a) Warm up and stop the engine.
(b) Remove the intake air surge tank (see page 11-13).
(c) Disconnect the injector connectors.
(d) Remove the ignition coils.
(e) Remove the spark plugs.
(f) Inspect the cylinder compression pressure.
(1) Insert a compression gauge into the spark plug
hole.
SST 09992-00500
(2) Fully open the throttle.
(3) While cranking the engine, measure the compres-
sion pressure.
Compression pressure:
1.5 MPa (15.3 kgf/cm
2, 218 psi)
Minimum pressure:
1.0 MPa (10.2 kgf/cm
2, 145 psi)
Difference between each cylinder:
100 kPa (1.0 kgf/cm
2, 15 psi)
NOTICE:

Always use a fully-charged battery to obtain engine
speed of 250 rpm or more.

Check the other cylinder's compression pressure in
the same way.

This measurement must be done as quickly as pos-
sible.
(4) If the cylinder compression is low, pour a small
amount of engine oil into the cylinder through the
spark plug hole, then inspect again.
HINT:

If adding oil increases the compression, the piston rings
and/or cylinder bore may be worn or damaged.

If pressure stays low, the valve may be sticking or seated
improperly, or there may be leakage past the gasket.
10. INSPECT CO/HC
HINT:
The ECM properly controls the CO/HC concentration in the emission gas.
(a) Start the engine.
(b) Run the engine at 2,500 rpm for approximately 180 seconds.
(c) Insert the CO/HC meter testing probe at least 40 cm (1.3 ft) into the tailpipe during idling.
(d) Check the CO/HC concentration at idle and/or at 2,500 rpm.
HINT:
When doing the 2 mode (with the engine is at idle and at 2,500 rpm) tests, these measuring order are pre-
scribed by the applicable local regulations.
If the CO/HC concentration does not comply with the regulations, troubleshoot in the order given below.
(1) Check the heated oxygen sensor operation (see page 05-126).
