        11 (HU) - 12 (E) Headlight dimmer switch hi beam Below 1 Ω

        Tech Tips

        Perform the flash and high beam inspection with the light control switch on head.

    3. Inspect the turn signal switch.


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

        Standard Resistance
        Tester Connection Switch Condition Specified Condition
        13 (TR) - 12 (E) Turn signal switch right turn Below 1 Ω
        13 (TR) - 12 (E) Turn signal switch right lane change Below 1 Ω
        13 (TR) - 12 (E) Turn signal switch neutral 10 kΩ or higher
        15 (TL) - 12 (E)
        15 (TL) - 12 (E) Turn signal switch left lane change Below 1 Ω
        15 (TL) - 12 (E) Turn signal switch left turn Below 1 Ω

    4. Inspect the fog light switch.


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

        Standard Resistance
        Tester Connection Switch Condition Specified Condition
        4 (BFG) - 3 (LFG) Fog light switch off 10 kΩ or higher
        2 (B) - 3 (LFG)
        4 (BFG) - 3 (LFG) Front fog light switch on Below 1 Ω
        4 (BFG) - 3 (LFG) Rear fog light switch on Below 1 Ω
        2 (B) - 3 (LFG)

        If the result is not as specified, replace the headlight dimmer switch.
