Aurion 09 reverse sensor problems with towbar

[Drago]

Just had a towbar fitted to my 09 Aurion, now the reverse sensors go off for no reason when reversing without a trailer. Can anyone assist

Are they going off as if you have backed up really close to something? If so they may be sensing the top of the tow bar. Did you have the tow bar fitted at a Toyota dealer? If you had it fitted by Toyota I would take it back and explain the problem to them, if it is because of the placement of the tow bar they should fix it free of charge. If its not because of the tow bar, is your car still under warranty?

Will it stop if you take the ball off? And put it on only when you want to tow.

Sensors sit higher than the towball by a long way on mine. Possibly messed up when connecting up the wiring?

No the towbar was fitted by an independant fitter and since then the sensors go off not every time but most times I reverse.

I think I remember reading here a while ago that if you don't use the genuine tow bar for the Aurion you will have this problem.

Failing that check the fuse for the sensors?

Do you have pictures you could put up at all? If you do that would really help.

It is my understanding that the wiring looms + trailer plug fitted by Toyota (and by Hayman Reece installers) incorporated a suppressor to stop interference between the towbar and reversing sensors. Perhaps an enquiry to Toyota to see if you can get hold of a suppressor.
