Toyota Yaris: Headlight Dimmer Switch / Inspection
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°).

WARNING
When removing the fuel-filler cap, loosen the cap slightly and wait
for
any hissing to stop, then remove it
Fuel spray is dangerous. Fuel can burn skin and eyes and cause illness
if
ingested. Fuel spray is released when there is pressure in the fuel tank and
the fuel-filler cap is removed too quickly.
