Remote start issue aftermarket unit

[John Buca]

Hi I'm new here, I own a 2022 Ford Ranger 3.2 Diesel, built in South Africa.

The problem I have is the following: I bought a remote start unit from J's Alarms and car audio.
I installed it via the OBD connector and the unit works perfectly.
Press the lock button on the original remote 3 times and the car starts.
The only problem is that it only works when a door is open (front or back, doesn't matter).
If the doors are closed, the remote starter doesn't work.

The solution I got was the following: "I have only heard of this issue in UK made vehicles, What they do to bypass this is add a toggle switch to one of the door pins to trick the car into thinking the door is open so it will start."

Now my question is: How do I do this?
Can someone help me with this and explain to me what to do?

Thanks in advance.

any chance the OBD port isn't getting power with the engine off unless a door is open? I'm not an engineer and am really taking a wild shot in the dark, but... it would seem to make sense that, with the port not getting power, your plug-in module isn't working.

Good Luck!

No, the unit would not work if there was not power to the OBD port.
Pin#16 is always HOT.

The issue is the ability of the module to - Wake the Can Bus circuits, which is done when the door is opened.
Now since I do not know the module and its operation (FOB), it may be a button sequence.
Lock - Start / Start (or similar) sequence to get the FOB to wake the truck.

As for the factory remote start, the doors have to be closed and locked for it to work, in fact if I recall you can hear the door locks trigger (to lock) when remote starting (Via Ford Pass), this is the reason for when via FOB you must hit the lock button

So, it may need some programming changes so the BCM can be woken up from the FOB and this will Enable the Remote Start Feature and also add the display to the IPC, which the OP needs to check if the - Remote Start menu is present on the IPC display.

Now I cannot CONFIRM this will work, but these (As-Built) data lines tie into Remote Start and needs changed to match a truck that has remote start (factory)
The part I cannot confirm is - Will this allow (FOB -remote start) to Wake the circuit with door closed. I think it will as you are reprogramming the BCM and enabling remote start.

Using Forscan:

IDK, if there is anything in the (easy menus for this) I like to dig into the actual lines and see what each code does - with the easy menu, you do this blindly and rely & trust Forscan to make the changes automatically - without knowing precisely what is being changed.

So, we need to Enable - Remote Start in the BCM and also Enable the Remote Start - Menu on the IPC screen.
Take a picture or write down what your existing lines read before you make changes, especially since you are a (ROW) and I cannot see what your (As-Built) data lines are. I can see the US Version across all trims, and you can download your As-Built Data from the Ford Services website by typing in your VIN#

So, you can try changing the following As-Built Data lines to get the Remote Start to work.
I know some have added - Start-X, but I do not know without checking the threads for them if the owners had to make any changes with Forscan to get it to work. I just know that for the addition of the (Permitter Plus) module (Ford) it requires As-Built Reprogramming

BCM:
Remote Start (Enable/Disable)
726-22-02 - 0001-0001-AAFD (xxx1-xxxx-xxxx) 1=enable 0-disable
(Change the 0 to a 1)

Remote Start Duration: Factory is set to 15 Minutes, for this line.
726-20-01 - 0303-0303-035D (x3x3-x3x3-x3xx)
0=Off / 1=5-minutes / 2=10 minutes / 3= 15 Minutes
(Change 0 to a 3) for factory settings

Remote Start Lighting (Control) Parking Lights (on) with remote start
726-41-02 - 0101-0101-0074 (xxxx-xxx1-xxxx) 1=enable 0-disable
(Change 0 to a 1)

IPC:

Remote Start Feature (Enable/ Disable)

720-02-02 - 0B88-F9B7 (Factory Lariat Setting)

720-02-02 - 1008-A9EC (Factory XL Setting)

Now this one is tricky as it incorporates various controls to Enable/Disable
so, this ties in the Trim Level (options) Heated Seats, Rear Window Heat etc.

So, for this one I will need to know what your line reads (here)
But the breakdown is this and it depends on the current features of your truck
0xxx-xxxx - Park Lock Control - Disable --- 1xxx-xxxx - Enable (So PB vs Keyed Start)
xBxx-xxxx - Passive Entry/Passive Start - Enable - x0xx-xxxx - Disable
xx8x-xxxx - Rain Sensing Wipers - Enable --- xx0x-xxxx - Disable
xxx8-xxxx - Unknown - But both truck ops are the same so it's not a setting that needs changed
xxxx-Fxxx - Heated Seats Climate Settings -Enabled - xxxx-Axxx - Disable
xxxx-x9xx - Remote Start/Rear Defrost - Enabled - so the same for both trims

Note: the last (2) hex codes of any line is the - Checksum for the Line-Code and will change automatically when anything on the line is changed. (it is a validation) of a valid program code.

How about pressing Unlock-Lock-Lock-Lock? Would the first Unlock wake the CAN bus? It might need a fourth Lock if the module assumes the door is locked before the three presses.

Remember this is a '22 ROW 6G Ranger, not a 5G. As most of us are NA 5G owners. We not be much help with this.

Thanks for all the replies.
I just found out that if I click/lock the door latch all the way with a screwdriver while the door is open, the remote start does not work.
If I put the door latch in the first position to lock with the screwdriver, the remote works. And if the door latch is open it works too.

So I do not think it has anytig to do with the power of the OBD that is connected with the remote start unit.

The remote start works with the original fob/remote of my car by pushing lock-lock-lock 3 times.

As far as I have search the web, I think it has something to do with the door latch switch??

Thanks to all for replying and have a good weekend.

 

[John Buca]

Thank you for the tremendous information!
The system I installed works un the US models flawless, but mine was build in South Africa.
They had the same problem with the UK versions and that is how I got the suggestion to bypass this to add a toggle switch to one of the door pins to trick the car into thinking the door is open.

But I do not know how to do that.

Did they post any other info of it working and did they use Door Lock or Door Ajar Circuit? or was this only an IDEA?

My concern is improper operation & faults generated by doing it.
Such as Door Ajar Warning - When Driving / Dome Lights staying on with door closed and battery drain, truck not completely shutting down modules and going into sleep mode in addition the alarm will never be armed.

IDK specifically what the different factor is between the US & ROW Ranger is for it not to work, for the most part as far as I know, the wiring is closely the same but there are variances in pinouts and switches.
I would have to see the wiring diagram for the module and the ROW truck (specifically the door lock circuit) I can only see US Version Diagrams.

I truly think it is a programming issue to enable the module to wake the truck up, this is closing the PCM Power Relay.

But if they are using the Door Ajar switch you can add a By-Pass toggle to disable the switch

The switch is closed and grounded when the door is closed, when opened the ground is removed.

So, you could get access to the Door Latch Switch, pull the connector and locate the Black/Grey Wire, this is the Ground - come up about 12 inches or so from the connector and cut the wire and then tie in a Toggle Switch in between the now (2) wire ends.
The Toggle Switch is now controlling the ground

With the Door Closed:
1 position will be as (stock) normal position (Closed) and the other will be altered position (Open) with the door closed.

This will work in theory to keep the circuit active, but for how long until the BCM shuts down the circuit. Battery Run Down Protection.
This is why I am questioning if they got it to work without creating downline issues or was this just an idea someone posted.

 

[John Buca]

Hello Airline Tech, and thanks again for your input. Much appreciated.

But your concerns were correct. I have the ground of the door latch switch and the interior light stays on and I also get a message on the dashboard that my back door is not closed properly.

So that is not the solution to the problem.

The suggestion to do a bypass with a toggle switch came from the seller of the remote start system.

It is not vital to have a remote start system, but I thought it would be a nice addition to such a nice car as a Ford Ranger.

I am starting to believe more and more that it is a programming issue of the remote start system that I bought on Ebay.

The remote start of Fordpass unfortunately does not work in the country where I live and cannot be activated here.
I live in the Caribbean, have a Ford Ranger that was made in South Africa and now have to walk all the way to my car to start it so that the air conditioning is cold before I go for a drive......
Luckily we have enough cold beer on the island.

If anyone has any ideas or options to tackle this problem, please give me suggestions.
Thanks for brainstorming with me

I'm in the US with a petrol '22 Ranger.

I installed the Start-X remote starter.

The doors and hood must be closed for mine to work (doesn’t matter if the tailgate is open or removed).

For mine, I had two options when programming. The 3-lock sequence like you have OR lock-unlock-lock. I did the latter.

Do you have the option to change how you start it?

If not, have you tried to reprogram it?

I'd probably fully disconnect it and then reinstall/reprogram it - good luck!

So, I have a question - and this ties into the BCM & IPC settings I posted above since you have an (XL)

The Start-X - works for you, and I do not remember previous thread if you have or had to add the IPC (Remote Start) menu screen.

The reason I ask is the fact that the BCM appears to be programmed for the Remote Start across all trims (US Versions) and all match the BCM (Hex Lines) Codes
So, this can be the reason why all US Versions work with the Aftermarket Units and the Ford Permitter Plus (Module) - Without Forscan Help.

However -I think that although it works, the IPC menu is not displayed to customize settings for it (Remote Start)
This is where the Trims (As-Built) Data changes across the trims

So, for the OP, I have a feeling that your truck has the BCM side of the settings turned off (disabled)

Now if you do not have Forscan to visually look at your As-Built files, you should be able to go here: Type in your VIN# and you can download the As-Built files for your truck.

Look for the Modules 720 & 726 - These are the IPC (720) & BCM (726) data lines

Note what the data lines are for:
720-02-02
726-20-01
726-22-02
and post what they read, I am mostly focused on the BCM (726) lines, if they do not match what I have posted above (THIS IS YOUR ISSUE) as I strongly feel your (ROW) is not programmed the same as the US Version and needs Forscan to change it.

You are correct, there was no setting that I edited in any menu screen.

I have the XL with 101A and ASS delete.

The Start-X has been reliable for me since November 17, 2022 - never touched it after the install.

The Start-X install entailed installing the OBD port T harness, a small connector then into the Start-X unit, and "programming" which is laid out in the images below that I cobbled from Amazon.

I don't see where you make the choice between lock-unlock-lock and lock-lock-lock (can't find the manual page).

On another note, this may have solved the mystery I had months ago when the truck would restart after stepping out of it and locking the doors:

"Turning the key to on and then to off does not totally shut the remote starter. Turning the key on and then off may cause the remote starter to start the truck again."​
