Yellow warning brake and triangle

So I’m driving, fast right turn and a yellow word “brake” and the yellow triangle with the circle around it came on. Both yellow and at the same time. Wasn’t running as well on way home .

This is not a flashing light, it’s on and solid and does not go off.
What is this?

I have a code reader? Gonna look now

What caused this and does it happen often

Thanks

Rob

Sounds like the steering wheel sensor is going bad

There are previous posts on this phenomenon. The steering wheel sensor can be reset/calibrated, it sometimes just "loses its way". If I recall, another culprit for this code could also be a TPMS monitor sensor (the piece on the car) going bad.

Could be steering angle sensor, wheel sensor, or the DCS/ABS pump. In my case it was the pump. I could clear the code but it would come right back again the next time DCS was triggered.

Some folks have been able to clear a steering angle code by turning the rack fully lock-to-lock a few times. My guess is that it resets and/or frees up the sensor.

^WHS. Turning lock to lock several times is part of the reset process after clearing the code. Can't hurt to try just turning lock to lock
