Hi,

The cruise control in my 2010 RX450h doesn't work at the moment. If I press the end of the stalk after starting (and not moved), I get the option to select the distance from car in front/speed but, if I move off it immediately errors. It also errors if I press the stalk while moving.

I suspect my front bumper has been changed in the past, I'm wondering if there is a radar cruise control front emblem vs a non radar cruise emblem? Is that a thing?

There are no codes stored according to the Delphi OBD reader.

Thanks

Just to follow up, I had the ecu codes read with Toyota Techstream, looking at the live data it was clear there are 2 stop switches, one of mine was always on.

Both stop switches are in the brake pedal switch, if one fails, your cruise control won't work but your brake lights will.

Replacing the brake switch fixed the issue.
