INSPECTION
PROCEDURE
1. INSPECT HEADLIGHT DIMMER SWITCH ASSEMBLY
(a) Inspect the light control switch. (1) Measure the resistance according to the value(s) in the table below. Standard Resistance: Tester Connection | Switch Condition | Specified Condition | 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. | | *a | Component without harness connected (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. | | *a | Component without harness connected (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°).

(d) Inspect the front fog light switch. (1) Measure the resistance according to the value(s) in the table below. Standard Resistance: Tester Connection | Switch Condition | Specified Condition | 9 (BFG) - 8 (LFG) | Front fog light switch off | 10 kΩ or higher | 9 (BFG) - 8 (LFG) | Front fog light switch on | Below 1 Ω | HINT: If the result is not as specified, replace the headlight dimmer switch assembly. | | *a | Component without harness connected (Headlight Dimmer Switch Assembly) | | |
