I bought new Toyota Yaris Altis December 2018. Yesterday reverse parking sensor stopped, cannot see on screen. Checked manual cant find much inormation. It would be appriciated if someone advices what can start sensors ? Or is it gone off and I need to install new by going to Toyota dealer ? For advice information thanking in advance.

I assume you mean Yaris Ativ and you are referring to the reversing camera which displays on the 7" head unit screen?

If the display works normally in other modes (radio etc) then the fault is either related to the camera or its wiring.

The camera is located in the boot lid above the number plate. The wiring runs from the boot lid to the body of the car - check for damage.

When the cameras themselves fail its usually due to water ingress - look for water behind the lens. I suspect pressure washing at car washes might be to blame. Its a relatively common problem in UK on all models of cars.

Replacement of the camera is easy but in UK the cameras are extremely expensive from Toyota (over £450 last time I bought one - that ฿18k) - don't know Thai price but brace yourself for a shock!

 

 

check if reverse light comes on when put in reverse. i don't have a camera, but my reverse parking aid played up when the gearbox switch failed. cost less than 300 baht for the non genuine switch. hope you get lucky.
