INSPECTION

PROCEDURE

1. INSPECT TURN SIGNAL SWITCH

(a) Check the resistance.

(1) Measure the resistance according to the value(s) in the table below.

Standard Resistance:

Light Control Switch

Tester Connection	Condition	Specified Condition
z6-7 (A) - z6-5 (EL)	Light control switch in AUTO position	Below 1 Ω
z6-3 (T) - z6-5 (EL)	Light control switch in tail position	Below 1 Ω
z6-12 (H) - z6-5 (EL)	Light control switch in head position	Below 1 Ω

Dimmer Passing Switch

Tester Connection	Condition	Specified Condition
z6-11 (HF) - z6-5 (EL)	Dimmer switch in high flash position	Below 1 Ω
z6-16 (HU) - z6-5 (EL)	Dimmer switch in high position	Below 1 Ω

Fog Light Switch

Tester Connection	Condition	Specified Condition
z6-4 (B) - z6-5 (EL)	Fog light switch in rear position	Below 1 Ω
z6-13 (BFG) - z6-5 (EL)	Fog light switch in front position	Below 1 Ω

Turn Signal Switch

Tester Connection	Condition	Specified Condition
z6-8 (TR) - z6-5 (EL)	Turn signal switch in neutral position	10 kΩ or higher
z6-14 (TL) - z6-5 (EL)	Turn signal switch in neutral position	10 kΩ or higher
z6-8 (TR) - z6-5 (EL)	Turn signal switch in right turn position	Below 1 Ω
z6-8 (TR) - z6-5 (EL)	Turn signal switch in full right turn position	Below 1 Ω
z6-8 (TR) - z6-6 (CR)	Turn signal switch in full right turn position	Below 1 Ω
z6-6 (CR) - z6-5 (EL)	Turn signal switch in full right turn position	Below 1 Ω
z6-14 (TL) - z6-5 (EL)	Turn signal switch in left turn position	Below 1 Ω
z6-14 (TL) - z6-5 (EL)	Turn signal switch in full left turn position	Below 1 Ω
z6-14 (TL) - z6-6 (CR)	Turn signal switch in full left turn position	Below 1 Ω
z6-6 (CR) - z6-5 (EL)	Turn signal switch in full left turn position	Below 1 Ω

If the result is not as specified, replace the turn signal switch.

HINT:

The left turn or right turn condition indicates a condition in which the turn signal switch will return to the neutral position after releasing your hand from the turn signal switch (turn signal switch is operated approximately 6.3°).
The full left turn or full right turn condition indicates a condition in which the turn signal switch will not return to the neutral position after releasing your hand from the turn signal switch (turn signal switch is operated 10.5°).
