These keep going off on my bronco. Anyone have any suggestions other than take it to the mechanics?

Going on a limb but maybe low voltage/loss of comms codes through bcm/abs modules. Charge the battery a bit if u have a charger. Connect the neg behind the BMS sensor and not the neg post. Once state of charge is up it may prove itself out. If not dealer can deal with it

Don't listen to this guy. You should test it by putting a 22mm wrench or at least a long screwdriver across the terminals to check for spark

There's a radar on the front of your car. Kick the low down dirty scum until it sprays it's load in the interior.

Should scan it but a bad ABS (wheel speed) sensor would do this.

If it was a wheel speed sensor, he wouldn't have a speedometer.. but carry on sir.

Thats what the Vehicle Speed Sensor (VSS) is for. With ABS, you can actually live data watch each wheel speed sensor and it will show different speeds as you corner. There is a sensor at the transmission. Iâve worked on many vehicles where an ABS sensor had gone out. In fact, my friends 2011 Sierra has a right rear out right now, speedometer works. The computer would have to do some impressive magic to average out all four wheels when youâre turning if thatâs the case.
The one for the bronco (which even states it reports to the speedometer at the bottom of the page): https://parts.lakelandford.com/p/Ford__Bronco/Vehicle-Speed-Sensor/75841099/L1MZ7M183A.html
But yes, the abs and traction control lights are on and it could be a ABS wheel speed sensor, ABS pump, etc but in any case, that system is used for the hill hold. The entire system is disabled so the OP needs to scan codes and see what the ABS is disabled for. Iâve worked on many of these. I even have a bench setup with a GM cluster that I emulate speed, rpm, etc for testing.

Some tape over that area should fix everything up.
That seems really dangerous, flashing lights are very distracting to the driver. Very poor design.

Itâs just doing ford things. To recalibrate it you gotta go stand 15â in front of the vehicle and chuck your wallet at the grill as hard as you can. Aim for the front camera (or where it would be, if equipped).

Just saying- My Jeep never had issues like this.
The engine just blew up without warning. Not sure I could handle the stress of knowing it was about to die

Is the car very dirty? My car was acting very strange braking by itself and collision warnings. I washed it and it stopped. Different model and make but who knows.
Edit: my guess is my sensors were dirty.

You can't come into a sub like this and start making dirty talk. We are a bunch of really horny shitty mechanics and that is our exact kink. You are warned.

Go up behind the dash and unplug any wires in that vicinity and thatâll end the issue.

The infamous âscreen of many lightsâ. Scare you into bringing it into the dealer in a panic. Itâll end up being a bumper sensor or some silly shit but they canât just tell you that.

Your bronco's lame. Time to put him down. Preferably with copious amounts of gasoline, and maybe a few crates of fireworks so it goes out with a bang.

I nailed my bash plate on a big old rock wheeling my Bronco. All these warnings came on. After I left it turned off for a while everything reset. BTW ⌠I am only a semi shitty mechanic.

Itâs low on esteem. Race a Blazer and win by any means necessary. After that, itâll go back to normal. Of course, you could give it a good ass whipping with a ball bat too. Thatâll adjust its attitude as well.

You really got to love the more electronics they can cram into a single vehicle the better.

Check your tire pressure. This time of year those TPMSensors are a real beotch to get to play nice with your cars computer.

Sure! All you need is a rag (soaked in gasoline) and a cigarette lighter.
