CHECKING THE BULBS AND BULB
SOCKETS
NOTE:
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 conti-
nuity 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 vehicle are shown in the
following illustration.
• Bulbs “a” and “b” are used for the headlights
and usually use a bulb holder that must be
detached before removing the bulb. The ma-
jority of these types of bulbs can be removed
from their respective socket by turning them
counterclockwise.
• Bulbs “c” are used for turn signal and
tail/brake lights and can be removed from the
socket by pushing and turning the bulb coun-
terclockwise.
• Bulbs “d” and “e” are used for meter and indi-
cator lights and can be removed from their re-
spective socket by carefully pulling them out.
Checking the condition of the bulbs
The following procedure applies to all of the
bulbs.
1. Remove:
• Bulb
WARNING
Since headlight bulbs get extremely hot,
keep flammable products and your hands
away from them until they have cooled
down.
CAUTION:
• 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 a 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 a headlight bulb gets
soiled, thoroughly clean it with a cloth
moistened with alcohol or lacquer thinner.
2. Check:
• Bulb (for continuity) (with the pocket tester)
No continuity → Replace.
Pocket tester
90890-03112
NOTE:
Before checking for continuity, set the pocket
tester to “0” and to the “Ω x 1” range.
Check each bulb and bulb socket for damage
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.
