Compression CheckS7RS0B1404001
Check compression pressure on all 4 cylinders as
follows:
1) Warm up engine to normal operating temperature.
2) Stop engine after warming up.
NOTE
After warming up engine, place transaxle
gear shift lever in “Neutral”, and set parking
brake and block drive wheels.

3) Disconnect negative cable at battery.
4) Remove engine cover.
5) Remove air cleaner assembly and air suction hose referring to “Air Cleaner Components”.
6) Remove cylinder head upper cover.
7) Disconnect ignition coil couplers (1).
8) Remove ignition coil assemblies (2) with high- tension cord (3).
9) Remove all spark plugs.
10) Disconnect fuel injector wires (4) at the coupler. Driving condition Valve timing Target of control Effect

Downloaded from www.Manualslib.com manuals search engine 4A-8 Brake Control System and Diagnosis:
Excessive Pedal Travel InspectionS7RS0B4106003
1) Start engine.
2) Depress brake pedal a few times.
3) With brake pedal depressed with approximately 300 N (30 kg, 66 lbs) load, measure brake pedal to wall
(dash panel silencer) clearance “a”. If clearance “a”
is less than specification, the most possible cause is
air in lines. Should clearance “a” remain less than
specification even after bleeding of system, other
possible infrequent cause is booster push rod length
out of adjustment.
• Bleed brake system. Refer to “Air Bleeding of Brake System”.
Brake arm pedal to wall clearance “a”
When pedal depressed at 300 N (30 kg, 66 lbs):
over 75 mm (2.95 in.)
Brake Fluid Level InspectionS7RS0B4106004
1) Check master cylinder, reservoir and reservoir hose (if equipped) for crack, damage and brake fluid
leakage. If any faulty condition exists, correct or
replace.
2) Check that brake fluid level is between MAX and MIN marks on reservoir.
NOTE
Be sure to use particular brake fluid either as
indicated on reservoir cap of that vehicle or
recommended in owner’s manual which
comes along with that vehicle. Use of any
other fluid is strictly prohibited.
Fluid level should be between MIN and MAX
lines marked on reservoir.
When brake warning lamp lights sometimes
during driving, replenis h fluid to MAX level.
When fluid decreases quickly, inspect brake
system for leakage. Correct leaky points and
then refill to specified level.

CAUTION!
Do not use shock absorber fluid or any other
fluid which contains mineral oil. Do not use a
container which has been used for mineral oil
or a container which is wet from water.
Mineral oil will cause swelling and distortion
of rubber parts in hydraulic brake system and
water mixed into brake fluid will lower fluid
boiling point. Keep all fluid containers
capped to prevent contamination.

Stop Light Switch AdjustmentS7RS0B4106005
Adjustment should be made as follows. Pull up brake
pedal toward you and while holding it there, adjust
switch position so that clea rance between end of thread
and brake pedal is as specified. Then lock it by turning
clockwise.
Clearance between brake pedal and stop light switch
“a”: 1.2 – 2.2 mm (0.05 – 0.08 in.)

Troubleshooting
Time Lag TestS7RS0B5104015
This test is to check conditions of clutch, brake and fluid pressure. “Time lag” means time elapsed since select lever is
shifted with engine idling till shock is felt.
1) With chocks placed before and behind front and rear wheels respectively, depress brake pedal.
2) Start engine.
3) With stop watch ready, shift select lever from “N” to “D” range an d measure time from that moment till shock is felt.
4) Similarly measure time lag by shifting select lever from “N” to “R” range.
Gear shifting time lag
“N” → “D”: Less than 0.7 sec.
“N” → “R”: Less than 1.2 sec.
NOTE
• When repeating this test, be sure to wait at least one minute after select lever is shifted back to “N”
range.
• Engine should be warmed up fully for this test.
• Repeat test 3 times and take average of those data for final time lag data.
