Standard Resistance:

Tester Connection

Switch Condition

Specified Condition
*1: w/ Light Control Switch Off Position

*2: w/ Light control switch DRL OFF Position

18 (T) - 15 (EL)

Light control switch off*1

Light control switch DRL OFF*2

10 kΩ or higher

20 (A) - 15 (EL)

19 (H) - 15 (EL)

20 (A) - 15 (EL)

Light control switch AUTO position

Below 1 Ω

18 (T) - 15 (EL)

Light control switch tail position

Below 1 Ω

18 (T) - 15 (EL)

Light control switch head position

Below 1 Ω

19 (H) - 15 (EL)

HINT:

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

(b) Inspect the headlight dimmer switch.

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

Standard Resistance:

Tester Connection

Switch Condition

Specified Condition

17 (HF) - 15 (EL)

Headlight dimmer switch flash position

Below 1 Ω

14 (HU) - 15 (EL)

14 (HU) - 15 (EL)

Headlight dimmer switch high position

Below 1 Ω

HINT:

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

(c) Inspect the turn signal light switch.

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

Standard Resistance:

Tester Connection

Switch Condition

Specified Condition

12 (TR) - 15 (EL)

Turn signal switch neutral position

10 kΩ or higher

11 (TL) - 15 (EL)

12 (TR) - 15 (EL)

Turn signal switch right turn position

(self cancel condition)

Below 1 Ω

12 (TR) - 15 (EL)

Turn signal switch right turn position

(cancel ratchet operation condition)

Below 1 Ω

12 (TR) - 13 (CR)

13 (CR) - 15 (EL)

11 (TL) - 15 (EL)

Turn signal switch left turn position

(self cancel condition)

Below 1 Ω

11 (TL) - 15 (EL)

Turn signal switch in left turn position

(cancel ratchet operation condition)

Below 1 Ω

11 (TL) - 13 (CR)

13 (CR) - 15 (EL)

HINT:

  • If the result is not as specified, replace the headlight dimmer switch assembly.
  • The self cancel condition indicates when the turn signal switch returns to the neutral position when releasing your hand from the switch (switch is operated within 7°).
  • The cancel ratchet operation condition indicates the condition when the turn signal switch does not return to the neutral position even when releasing your hand (switch operation is 12°).
