Hi,
I wonder if anyone can help me please? My wife has a 2010 Mazda 6 with 37,000 miles on it. A week ago, the DSC Off, Brake, and traction warning lights started coming on together intermittently. They are still coming on and off. They light up within about 2 seconds of each other, and then all go off together - sometimes within a few minutes, other times they stay on for an hour. When the DSC Off light is on, pressing the DSC button has no effect on the state of the warning light. Similarly, engaging the hand brake has no effect on the state of the Brake warning light. But when the lights are not on, engaging the brake or DSC DOES change the state of the corresponding warning lights.
Does anyone have any suggestions about what might be causing this? If I had to make a guess, I would say that it is related to a faulty sensor, but I would really appreciate the input of an expert.
Many thanks for any help you can offer.

Frank.

 

You need to check the DTC's (codes). It sounds like a failing ABS/DSC module or possible loose connection at the module.

 

Thanks for your help Wrencher. I'll have a look at the codes this evening and update this thread with my findings.

Also could be a faulty or dying ABS/wheel speed sensor. Code check should lead you in the right direction.
