e-brake light, abs light, dsc light, and traction control light

[DarrenMon]

Hello. I'm new to the forum so I will expect to get flamed for who knows what reason.

My issue is on my 07 Mazdaspeed6, I've been getting my e-brake light, abs light, dsc light, and traction control light come on when I go over 140 km/h, but go away once I turn the car off, let it sit for a second and turn it back on.

Back in January/February, I had the rear speed sensor replaced since the same problem happened in 4th gear when I gave it hard. I've checked my brake fluid and it's full. I've talked to a buddy with a MS3 and said it may be my SWAS but it doesn't have the same symptoms as what I'm experiencing.

The car runs fine with the lights on. It's just an eyesore to see and I won't know if something is actually wrong should the lights come on.

Any ideas?

I realize the picture is upside down. I'm posting this thread from my phone and don't know how to fix it.

Well I don't know about it only happening at a certain speed could be a faulty speed sensor again.
I had all the lights come on from a faulty rear abs sensor. But my lights stayed on until I fixed the abs sensor.

Your picture is upsidedown...

I had something similar to this happen to me on a different platform. It ended up being a bad brain in my ABS module. I would turn my vehicle on and drive (no lights) then out of no where all my lights would light up.

I would first start out with checking all your connections. Then I would ohm out your sensors. If one of the sensors has a lower/ higher ohm value then the others you should eliminate the sensor that is out of tolerance.

Check to see what codes are showing; I checked mine and got C1233 and C1234 ABS codes, which are FL and FR wheel speed sensors/rotors.

My car did the same thing. Lights would come on only over 85mph. Turn car off no lights until I would hit 85 again. I ended up having a faulty left rear wheel speed sensor.

That's funny. I just had my rear speed sensor replaced a couple months ago. And yours happened at the same speed as mine. Maybe I'll have to get it looked at again....

Both of them?

So here's my take on this e-brake, dsc off, skid light, abs light on.

So someone on youtube had this issue but it was with a BMW, and he said that (for his car) if the parking brake came on with all these, then the problem is in the rear wheels. Now idk if thats true for our cars but i took a chance and took off the rear wheels first (had to take all wheels out any ways). And boom! rear left wheel's ABS wheel speed sensor wire was busted. So i did a cheap fix, i stripped the wire and soldered the same color wires together(i know i did a bad job on solder, it was really cold and it works!) and put some liquid electrical tape(obvious) and the moment i turned on the car, all those lights went off after some seconds. Now they go off normally. I am really lucky that i found the wire busted right in front of me. So just double check if any of your wires are busted maybe you could have a cheap fix like me!

All mine were all on and it was the front passenger side WSS that was bad.

Good stuff man glad you found the culprit.
