2007 Mazdaspeed 6 When accelerating past 70 MPH, the ABS

Customer Question

2007 Mazdaspeed 6 When accelerating past 70 MPH, the ABS light, parking brake light, TCS Off light, and Traction control icon light, all come on instantly. The engine continues to run fine and everything else works. When you turn the ignition off and on
the lights go off. Tires are new and correct size. Car has a cold air intake and large exhaust system.

Hello and Welcome! I'm Billy and i will assist you with your inquiry. Feel free to ask if any further info is needed.
My apologies for the delay, thank you for your patience.
Since the braking system modules are detecting faults (as triggering the warning lights), the first thing would be retrieving those fault codes to get a direction on what to check. Would you be able to get the fault codes (using a scan tool obviously)?
Customer: replied 2 years ago.
Took it to Autozone. No codes showed on their scanner. You mentioned brakes. Sometimes when slightly moving forward when applying the brakes where is a momentary buzzing in the front brakes. Almost like antilock brake sound but only for a second.

Hello,
The buzzing should be the ABS pump kicking in. Can you check using another scan tool, for ABS and ESP codes? (at autzone they usually check for engine codes, or what's known as P codes).
