3.INSPECT MAP LIGHT ASSEMBLY |
![]() |
Remove the map light assembly (LandCruiser RM000003YO9019X.html).
Measure the resistance according to the value(s) in the table below.
- Standard Resistance:
Tester Connection Switch Condition Specified Condition 8 (IG) - 23 (IG3) Always Below 1 Ω 24 (UP) - 5 (GND3) Tilt up switch pressed Below 1 Ω 24 (UP) - 5 (GND3) Tilt up switch not pressed 10 kΩ or higher 25 (DOWN) - 5 (GND3) Tilt down switch pressed Below 1 Ω 25 (DOWN) - 5 (GND3) Tilt down switch not pressed 10 kΩ or higher 27 (OPN) - 5 (GND3) Slide open switch pressed Below 1 Ω 27 (OPN) - 5 (GND3) Slide open switch not pressed 10 kΩ or higher 28 (CLS) - 5 (GND3) Slide close switch pressed Below 1 Ω 28 (CLS) - 5 (GND3) Slide close switch not pressed 10 kΩ or higher
