This only came out Tuesday, and the way I read the SSM, the customer as to complaint about the EBB towing issue to get the update.

Great, jlauer thanks for checking it out. Now we just need to get the word out to the rest of the non Bronco6g people towing the Bronco.

Yes, this eliminates the issue of the EBB being on when you start towing and then going away. It will always be off when in Tow Mode.

Yes that is my take, EBB goes off as soon as you enter the Tow Mode. And yes you will have to take it to the dealer and as for the update. Now a least you have a SSM mumber to show the dealer.

Here is the SSM (Special Service Message) that was posted today. SSM 51415 2021-2023 Bronco - Neutral (4-Wheel Flat) Towing - Inconsistent Brake Feel Through The Supplemental Brake System Customers who neutral (4-wheel flat) tow a 2021-2022 Bronco equipped with a 2.7L engine or a...

If this is true I do not want my changed. I need EBB on to get the full effect of my auxiliary bake system, that I installed before we new there was a issue.

Drive to a spot where there is a slight decline so the bronco will roll freely when placed in neutral. Now put the bronco in tow mode and let it roll a bit, then press on the brakes, do this a couple of times and you will instantly know if the EBB is asleep or not.. If it is asleep lock and...

More than likely it is road crud burning off the exhaust system. Keep the climate control system in in recirculated air mode for a while after you first start up the engine after towing.

If you have a 2.3, no you do not need a charge line with your setup. If you have a 2.7 and follow the the TSB no you do not need it. Depending on what Ford does to fix the Electronic Brake Boost issue on the 2.7 you may need a charge line.

Look at post #124 in this thread.

I don't have to remove the fuses. I have a device I build that resets the timer in the Bronco when I apply the brakes in the motorhome. So I always active boost when I need it.

I just when to a spot in the road by my house that has a slight decline. Put the Bronco in tow mode and let is roll a bit then pressed the brake pedal. EBB is still active. 2021 OBX.

This is from the 2023 online HTML manual. BUT the HTML manuals for 2021 and 2022 say the same thing. I will stop by my dealer Monday and see if they have a 2023 for a quick test.

Nope, just checked OASIS nothing new about towing. And your guess is good as any as to when it will happen.

If you do not pull the fuses, reference Ford TSB 22-2360, you will start out towing with full brake boost assist and then after 30 to 45 minutes it will go to zero.

Spec sheet shows the Raptor as EBB (Electronically controlled brake boost) EBB looks like this picture, note no vacuum chamber connected to the master cylinder next to the fire wall.

Tilzbow , right on , I was talking to a guy at the filling station the other day and he had no idea there was a problem. One of the nice's paint jobs I have seen. It was the Eruption Green Metallic with stripping to give it the old Eddie Bauer look with bullet hole aluminum wheels. Think is...
