Default Brake lights problem

A week ago I noticed my ABS and ASR come on at dash panel. No error codes but checked Wheel sensors and right front didn't give signal. Replaced the hub with sensor and checked with a wheel sensor tester, worked fine.

But the ABS and ASR lights still on after reseting with OBD, disconnected battery and drove the car for 30 minutes or so, also turned off engine and restarted several time but still ABS ASR lights on. Brakes feels fine.

THEN I found out that all three brake lights didn't worked! Guess this gives the ABS and ASR lights? Found out on internet that bad bulbs in third brake light can give this error. Checked the two bulbs in third light but they are fine. All other lights works fine as well (head-rear-hazard lights and turning signals).

So, to get to the bottom line; is there any fuse for the brake lights? I will check the brake switch tomorrow. Any other suggestions to check?

I had a similar issue and it turned out I was using the wrong bulb, there were 2 identical ones but the one with brass colored socket cured the problem, I don't recall the number but the one not working had a silver socket.... FWIW

Wow. Well, I have same bulbs as before the brake light turned off, and the two bulbs in third light are OK too.

Yes, I checked the fuses on side of dash and under hood, but there seems not to be any brake light fuse?! Only the fuse that also have the hazard and that works.

Yes, guess that's next part do check. Any drawings how to check the brake light switch? But strange ABS and ASR are set on dash panel, can the light up with a malfunction brake light switch?

Update: I have checked all rear bulbs and they are OK. Also for your information the cruise control works fine - but still no ABS/ASR lights off and missing brake lights on all 3 lights.

The Stop/Hazard fuse in the IP panel block is the one for the brake lights.

If the rear turn signals work, other than wiring there are only two parts that can affect the brake lights, the brake light switch and one section of the Hazard light switch that switches from brake lights to rear Hazard lights.

Update: Just checked the brake light switch and two wirings to the switch. All works, so no brake light switch broken. Strange. Any suggestions? EBCM error? But no OBD-errors.
