CHECKING THE BULBS AND BULB
SOCKETS
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 continuity
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
illustration.
• 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 sockets by turning them coun-
terclockwise.
Checking the condition of the bulbs
The following procedure applies to all of the
bulbs.

keep flammable products and your hands
away from them until they have cooled
down.

NOTICE
• Be sure to hold the socket firmly when re-
moving the bulb. Never pull the lead, other-
wise it may be pulled out of the terminal in
the coupler.
ELECTRICAL COMPONENTS
• Avoid touching the glass part of a headlight
bulb to keep it free from oil, otherwise the
transparency of the glass, the life of the
bulb, and the luminous flux will be adverse-
ly 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)
