Check that turn signal lamp blinks.
Reference Fig. : 4-6-4
Check point Check/Cause Action
1. Harness (1) Measure resistance between turn signal switch terminal
wire No.36 wire GR and combination meter connector
terminal wire No.36 wire GR.
Standard resistance : 10 Ω or less
(2) Measure resistance between turn signal switch terminal
wire No.35 wire G and combination meter connector
terminal wire No.35 wire G.
Standard resistance : 10 Ω or less
If above item (1) or (2) is NG, harness is faulty.•
Repair or replace
harness.
2. Turn Signal Switch When turn signal switch lever is moved, check continuity
between turn signal switch terminals.
Turn signal (L) : Between wire No.34 wire GY and
wire No.36 wire GR
Turn signal ( R ) : Between wire No.34 wire GY and
wire No.35 wire G
There is continuity in normal condition.
If there is no continuity, turn signal switch is faulty.

•
Replace turn signal
switch.
3. Combination Meter
(Turn signal indicator
lamp)
(1) When starter switch is ON, measure voltage between
combination meter terminal wires and ground terminal
wire.
Battery 12 V (+) terminal wire No.12 inlet wire Y and
ground terminal wire B
Starter switch (ACC) terminal wire No.314 inlet wire
BY and ground terminal wire B
Standard voltage : 12 V or more
(2) When starter switch is ON and turn signal switch is
moved, measure voltage between combination meter
terminal wires and chassis ground.
Turn signal (L) terminal wire No.36 inlet wire GR and
chassis ground
Turn signal (R) terminal wire No.35 inlet wire G and
chassis ground
Standard voltage : 12 V or more with constant intervals
If above items (1) and (2) are OK and turn signal indicator
lamp does not light, combination meter is faulty.
