Red light tyre pressure

[deksarge]

The tyre pressure warning light came on and was red, I checked the tyres and all were ok.
can I reset the warning light myself?
Thanks

I assume you have indirect tmps, wich uses ABS sensors to detect rotationspeed-differences between the wheels. Then you cant read the values on the screen.

Then ther must be a button somewhere, in my car its in the middle beside gearhandle.

But if message keeps coming back, check if no brake is stuck.
Feel the rims with your hand, if on one you burn your fingers, thats the hanging brake. Then cool your fingers under streaming water.

I had this hanging brake, and had to replace brakeclaw behind to fix it.

This indirect system, detects rotation differences, courced by deflection differences of tires. Then rolling circumference becomes different.
More deflection if pressure of tire goes down.
But in my case the heat of hanging brake warmed up the tire inside, wich highened up the pressure, so lesser deflection then the other wheels, so the other way around.
