Auto Hold 2015-2024


Recommended Posts

Has anyone used auto hold? Is it a feature for North America or other regions?

 

From the WSM:

 

Auto Hold


The auto hold feature is activated and deactivated through the use of the auto hold switch. For the system to activate, the vehicle must not be
moving, the driver safety belt must be buckled and the driver door must be closed. The ABS receives the driver safety belt buckle status from the
RCM, driver door status from the BCM, brake system pressure and the wheel speed sensors allow the ABS module to determine if the vehicle is
stopped. Once the previous conditions have been met the auto hold feature can be activated. Once the auto hold feature is activated, the driver
presses the brake pedal and the ABS module closes the isolation valves in the HCU to maintain the current brake system pressure at the wheel
ends. The ABS module maintains the pressure until the driver presses the accelerator pedal, shifts the transmission into PARK or after a specific
time limit has been reached. The ABS module engages the parking brake after 2-10 minutes, depending on the grade of incline the vehicle is
currently stopped on, the steeper the grade, the shorter the time.

The 2023/2024 owners manual has details on it's use, but I have never seen an Edge with it. It isn't in the 2022 owners manual. 2017+ MKX/Nautilus have it standard or later on in higher trim levels.

 

I have enabled and used it in a 2020 Explorer. It is a pretty nice feature, but if you don't understand it then when you go to take off it feels like the car is broken.

I just took delivery on a new 2024 Edge Titanium (301A package) with SYNC 4A. As far as I can tell, there is no Brake Hold option available in any of the vehicle settings. Also, there is not a button on the console to activate it. I called Ford support, they were no help at all. The owners manual contains the instructions on using it, but it does not correspond to what is available on the touchscreen.

I tried to get it to work a little while ago, but one of my modules, it might have been ABS, I don’t remember which one, was unable to support auto hold. I could not get the auto hold switch to appear on screen. I don’t have the latest version of Sync 4. The Lincoln Nautilus has auto hold though.

Hey, I have that on my 09..! It's set by putting the car in Park and stepping on the parking brake. (Seriously, am I missing something?)

 

Embarrassing when your at the grocery store, start to drive off and forget you left the parking brake on — squeeeeeeekkkkkk.

Everyone looks, you smile and cuss quietly.

And that was NOT me at the grocery store yesterday.

Auto hold lets you step on the brake in drive then release the brake and the brake will hold until you step on the gas again.

Sounds like something I would use driving through Starbucks. Start, stop, start, stop. (But then again, after driving over 60 years without it ........ . 🙂

It is extremely disappointing for Ford to put auto hold in the owner's manual, yet we don't have it on our vehicles.

I can confirm that my 2024 Edge ST has auto hold. I can't remember how to turn it on and off, but it does exist. It also was active on my 2021 Edge. 

 


I have never seen it before. Do you have a green auto hold icon on the instrument cluster? Can you share photos of auto hold working?

I believe there are 2 "auto" holds. Correct me if I'm wrong but,

 

1st one is on the "newer" cars and active. It is a "hill assist" hold for inclines

 

2nd one is able to be turned on or off. works differently and has different function, such as at a drive through and you don't want to keep your foot on the brake or put it in park, then you can turn it on and will keep you stationary while in Drive mode, until you hit the gas (or at least this is how the Sonata one works) Kind of silly in my opinion

Auto hold - When enabled (in a supported vehicle...) and you come to a complete stop, you can then let your foot off the brake, and the vehicle remains stopped until you give it gas.

hill start assist - If the vehicle senses you are on an incline, when you release the brake pedal it holds the vehicle for a few seconds or until you give it gas, allowing you time to get your foot from from the brake to the gas.

Stop and Go Adaptive Cruise - if stopped behind another vehicle, while brake is pressed, pressing RES + will put it in stop mode. You can release the brake and it will stay until you press RES+ or give it gas (and the vehicle in front you is moving), then it will go on its own with the space you set from the car in front of you, up to the speed you have set.

Thanks for the clarification. Based on that, my 2024 Edge does have hill start assist. It does not have auto hold. I am positive that my 2021 also had the same. 

It seems like there is some confusion regarding auto hold which is a physical button and not an option on the Edge?

For that VIN and generally for 2020 Edge -- which is the latest listed model year shown -- no mention or depiction of AutoHold switch or circuits/connectors in the China region Wiring Resource, though the China region Workshop Manual includes identification of the Instrument Panel Cluster's AutoHold Reconfigurable TellTale (RTT) indicator lamp in an IPC illustration...

...and as you mentioned previously, a single reference to AutoHold in the China region HTML format Owner's Manual, which is the only format in which the Owner's Manual is offered...

Good luck!

2024 Edge Workshop Manual - China region...

 

Placing your device cursor over underlined acronyms may yield popup full-words meanings for acronyms.

 

Auto Hold

The auto hold feature is activated and deactivated through the use of the auto hold switch located on the FCIM . For the system to activate, the vehicle must not be moving, the driver safety belt must be buckled and the driver door must be closed.

 

The ABS module receives the driver safety belt buckle status from the RCM and driver door status from the BCM , while brake system pressure and the wheel speed are received from ABS sensors. This information allows the ABS module to determine if the vehicle is stopped. Once the previous conditions have been met the auto hold feature can be activated. When the switch is pressed, the FCIM receives a ground signal from the auto hold switch and sends an auto hold message to the GWM over the HS-CAN3 . The GWM relays the message to the ABS module over the FD-CAN .

 

The ABS module then sends a message to the instrument cluster through the GWM indicating the auto hold feature has been activated and the instrument cluster illuminates the auto hold indicator.

 

The auto hold indicator illuminates when the IPC receives a message from the ABS module through the GWM .

 

Once the auto hold feature is activated and the driver presses the brake pedal, the ABS module closes the isolation valves in the HCU to maintain the current brake system pressure at the wheel ends. The ABS module maintains the pressure until the driver presses the accelerator pedal, shifts the transmission into PARK or after a specific time limit has been reached. The ABS module engages the parking brake after 2-10 minutes, depending on the grade of incline the vehicle is currently stopped on, the steeper the grade, the shorter the time.

 

Auto Hold Switch

The auto hold switch is a momentary contact, push button switch and is part of the FCIM .

 

Normal Operation and Fault Conditions

Vehicles equipped with EPB are also equipped with an auto hold feature. This feature must be enabled by the driver by pressing the auto hold switch once the driver seatbelt is buckled and the driver door is closed.

 

Pressing the auto hold switch in the FCIM enables the auto hold feature, but does not activate auto hold. When the switch is pressed, the FCIM sends a message to the ABS module indicating the system has been enabled. The ABS module then waits for messages from the RCM and BCM as well as ABS sensor information to indicate the auto hold feature can be activated. Once all criteria has been met, the ABS module activates the auto hold feature.

 

In the case of a system error, the instrument cluster displays messages and icons.

 

China region Search-function is not locating Auto Hold switch and other FCIM controls in Wiring Diagrams or Workshop Manual procedures, and no China-region Owner's Manual is shown.

 

Hopefully, the above verbiage provides you sufficient Auto Hold awareness at this stage of your inquiry.

 

Good luck!
