Check each switch for continuity with the pocket tester. If the continuity reading is incorrect, check the 
wiring connections and if necessary, replace the switch.
CAUTION:
ECA14370
Never insert the tester probes into the coupler terminal slots “a”. Always insert the probes from 
the opposite end of the coupler, taking care not to loosen or damage the leads.
NOTE:
•Before checking for continuity, set the pocket tester to “0” and to the “Ω × 1” range.

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 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
