How to stop hazards flashing under heavy braking?

[Niffty951]

Gents,

My google skills are failing me. What types of sensor are used to activate the indicators/hazards under heavy braking and/or how do I stop it happening?

If it's a pressure signal from the brake lines can it simply be snipped (looped) or can this be turned off as an option in the ECU usually?

There's nothing more annoying to me than driving around with the hazards on uncontrollably.

My car is an MX-5 ND but this must now happen on many cars!

Why don’t you try modulating your braking instead?

Pull the indicators /hazard light fuse out ?

They can't work with a broken circuit ,surely.

Because he's on a track day, and wants to properly haul on the brakes? I believe these systems are triggered by level of braking, not just sharp application.

On track, you can trigger ABS easily.

Also, on my particular car (BMW) and many others, it is done at a deceleration rate, not ABS triggering or a given brake pressure.

You can usually code it out via OBD with a suitable piece of software.

If you modulate so much that the lights don't come on then it's not really track driving anymore. They come on way before ABS being triggered.

Thanks for the OBD trick I'll get on ebay and find a good cable and software package for the car. I hoped it would be possible (like the seatbelt warning) but wasn't sure if I'd be wasting my time/not accessible.

As per this. The light flashing is triggered long before ABS intervention and even if you apply the brakes gently initially (to settle the car) and then increase pressure as the nose dips.

It seems to be pedal pressure related as you can stop sharply on cold brakes but as they warm up and you need to apply more pressure you trigger it more frequently.

Also possible but I'd like to keep the indicators if possible.

Yes and it would be pericoloso to not have indicators working on a TD anyway, always useful on a cool down lap or to help overtakes etc...

This happens on the Alfa Guila QF on track. Its not ABS - but rapid deceleration that triggers it. But it only happens in normal or dynamic driving modes - in race mode where traction stability etc are switched off this feature is disabled.

My 2006 Fiesta ST had this feature. Was just on the MFD menu to turn it off.

As said, likely to require coding through the OBD, whatever mazdas version of VCDS is kind of thing.
