        TURN SIGNAL SWITCH

        Tester Connection Condition Specified Condition
        9 (TR) - 12 (EL) Turn signal switch in neutral position 10 kΩ or higher
        3 (TL) - 12 (EL) Turn signal switch in neutral position 10 kΩ or higher
        9 (TR) - 12 (EL) Turn signal switch in right turn position Below 1 Ω
        9 (TR) - 12 (EL) Turn signal switch in full right turn position Below 1 Ω
        9 (TR) - 11 (CR) Turn signal switch in full right turn position Below 1 Ω
        11 (CR) - 12 (EL) Turn signal switch in full right turn position Below 1 Ω
        3 (TL) - 12 (EL) Turn signal switch in left turn position Below 1 Ω
        3 (TL) - 12 (EL) Turn signal switch in full left turn position Below 1 Ω
        3 (TL) - 11 (CR) Turn signal switch in full left turn position Below 1 Ω
        11 (CR) - 12 (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°).
