zero)
RACE MODE:
• Timer (which shows the time that has been
accumulated since the start of timer measure-
ment)
• Tripmeter (which shows the accumulated travel distance in timer measurement)
• Change tripmeter digits (capable of change to
any given ones)

c. Install the dowel pins and the camshaft caps.
TIP
• Tighten the camshaft cap bolts in a crisscross pattern from innermost to outer caps.
• Do not turn the camshaft when measuring the
camshaft journal-to-camshaft cap clearance.
d. Remove the camshaft caps and then mea- sure the width of the Plastigauge® “1”.

a. While pressing the tensioner rod lightly with
your fingers, use a thin screwdriver “1” to
wind the tensioner rod up fully clockwise.
b. When releasing the screwdriver by pressing lightly with your fingers, make sure that the
tensioner rod will come out smoothly.
c. If not, replace the tensioner assembly.

EAS27990CHECKING THE BULBS AND BULB SOCK-
ETS
TIP
Do not check any of the lights that use LEDs.
Check each bulb and bulb socket for damage
or wear, proper connections, and also for con-
tinuity between the terminals.
Damage/wear  Repair or replace the bulb,
bulb socket or both.
Improperly connected  Properly connect.
No continuity  Repair or replace the bulb,
bulb socket or both.
Types of bulbs
The bulbs used on this v ehicle are shown in the
illustration on the left.
• Bulbs “a” and “b” are used for the headlights
and usually use a bulb holder that must be de-
tached before removing the bulb. The majority
of these types of bulbs can be removed from
their respective socket by turning them coun-
terclockwise.
• Bulbs “c” is used for turn signal and can be re- moved from the socket by pushing and turn-
ing the bulb counterclockwise.
Checking the condition of the bulbs
The following procedure applies to all of the
bulbs.
1. Remove: •Bulb
EWA
WARNING
Since the headlight bulb gets extremely hot,
keep flammable products and your hands
away from the bulb until it has cooled down.
ECA
NOTICE
• Be sure to hold the socket firmly when re-moving the bulb. Never pull the lead, oth-
erwise it may be pulled out of the terminal
in the coupler.
• Avoid touching the glass part of the head- light bulb to keep it free from oil, otherwise
the transparency of the glass, the life of
the bulb, and the luminous flux will be ad-
versely affected. If the headlight bulb gets
soiled, thoroughly it with a cloth moist-
ened with alcohol or lacquer thinner.
2. Check: • Bulb (for continuity)(with the pocket tester)
No continuity  Replace.
TIP
Before checking for continuity, set the pocket
tester to “0” and to the “  1” range.
▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼
a. Connect the positive tester probe to terminal
“1” and the negative tester probe to terminal
“2”, and check the continuity.
b. Connect the positive tester probe to terminal “1” and the negative tester probe to terminal
“3”, and check the continuity.
c. If either of the readings indicate no continu- ity, replace the bulb.
