passanger weight sensor - Toyota Yaris Forums

hey guys

just wanted to ask a question regarding my passenger weight sensor. The light doesnt light up and i was wondering if anyone knows why?

also my interior light, when i put it on door and close the doors the light stays on and doesnt turn off.

Sounds like gremlins to me... Perhaps CT_Scott (resident electrical genius) has some more solid suggestions? Here's what I can come up with off the top of my head:

The weight sensor has different thresholds. I keep my passenger belt buckled all the time because my backpack weighs just enough to set it off. Perhaps you're expecting it to come on when the load isn't high enough to set it off?

For the dome light, does the door ajar light come on? It could be that there is some water damage in the wiring of your car, causing a short. Or the switch is just broken, making it work like "ON" instead of "DOOR". /shrug

Looking at the EWD, it appears that there is a bulb, rather than LED as the indicator, so I would suspect that the bulb is burnt out. If the sensor had an issue, the SRS warning light would come on.
