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 SOCK-
ETS
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 illustration.

Checking the condition of the bulb sockets
The following procedure applies to all of the 
bulb sockets.
1. Check: Bulb socket (for continuity)(with the pocket tester)
No continuity  → Replace.
NOTE:
Check each bulb socket for continuity in the 
same manner as described in the bulb section; 
however, note the following.
