Remote start issue aftermarket unit

[airline tech]

From what I can tell, everything on the Truck side should be set.

I think it's in the Start-X module or the T-Harness may not be wired (pinned) correctly.

I cannot find a wiring diagram for the Start-X (T-Harness) that they supply with the unit.
It taps in the backside of the DLC.

Now Referencing the Factory DLC (Front Facing Connector)
This is the OBD Port

Note:
Pin #16 is Power (Always Hot)
Pins #4 & #5 are Grounds

Pin #6 = HS Can High
Pin # 14 = HS Can Low

Pin# 3 = HS2 Can High
Pin # 11 = HS2 Can Low

Backside of the DLC - This is what Start-X is tapped into
This is C2431

So, the Start-X (T-Harness) is just jumper harness (pass-through) powering, non-start-x related wiring, and you will see a splice point or 2 wires running into the connector tap points.

So, T-Harness connects to this connector 14 Wires
Runs to the Start-X module connector
Then reconnects those 14 wires with either spliced wire taps or double wire into the connector pin slots.

I am thinking the Strat-X is tapping 4 total wires, I am not positive on this
But should be tapping:
Power & Ground
HS1 Can - High & Low

The reason for the Start-X, Lock -Unlock-Lock or whatever sequence options it has is to trigger a cycle on the HS1-Can bus to internally power the circuit to produce a (Start Signal)

When you use Start-X - do the doors Unlock & Lock (Cycle)?

Both Power Feeds into this connector are always HOT and Start-X I believe kills that power until it internally sees the (Button Press-Sequence) on the HS1-Can bus (with the doors closed)
or it drops the Ground for the Start-X module.

When you open the door, you are triggering the HS1-Can bus to power and Start-X is now powered, by either opening the power feed or applying the ground.
Depends on how it is wired.

It you can, as it is most likely wrapped if spliced - you will not see it
so hopefully they double wired into the connector end that connects to the backside of the Gateway DLC and note all wires they have tapped.

My ROUGH GUESS is they tapped Pins
#13 for Power
#19 HS1 Can Low
#20 HS1 can High
and Pin #1 or Pin#14 for Ground

As for the Truck, it should be set up, for some reason the Start-X module appears to not being able to power itself from the door lock cycles along the HS1-Can bus.

I did find this install video for a Ford

Start-X Remote starters - How to install - Amazon remote start - YouTube

Are you performing the initialization sequence like in the video?

Here is another install from another aftermarket unit.

J's Alarms 2020 Ford Ranger Remote Start How To Install Video

I did note in the comments section of this unit that some in the UK experienced the same issue you are having - only works with the door open, no resolution that I found.
between
So, if you are programming it the way the manual calls out and the way the video states and the unit is wired correctly then there is still a setting in the As-Builts that differs between the UK and US version trucks.

So, if this turns out to be As-Built data related, you may try this:

Get access to the Ford Services website:

Index - FordServiceInfo.Com

Download yours and then search for (On-Line) sales of other Rangers preferably in the US Market and use the posted (in the sales ad) for the truck - use the VIN# from that ad.
It would be easier if you find an exact trim to match yours to simplify the compare.

There are (on-Line) As-Built data compare programs but I never got them to work correctly.
So, I did this (Old-School) saved the As-Built data download as a PDF File and then printed it.

Side by Side compare each Hex File and (Highlight) the ones that differ.
Note: To make the process easier, only look at the last 2 characters on each line, if they differ between (the side by side compare) highlight the line.

Then use this website:

AsBuilt Databases - CyanLabs

In this website it will breakdown what each Hex-Line is: and what the line codes are programmed to do.
You will not see the PCM Hex-Codes though.
This is what I use to locate the Hex-Data and what it does, I have various trim levels and a excel spreadsheet made up for all the modules.

The lines that differ - use the website above and find that line in the modules and determine what option is different. (What specific is changed on the line?)

I would focus on the BCM & IPC
Since we have covered the Remote Start, then we need to look at any differences in door lock control, wake circuit-door ajar, anything to do with remote functions

NOTE: This is important
When you click on a - Module Database, you will see a POP-UP AD, just click close or the (X) in the top corner to CLOSE the ad.
Then the database will open to view it:
I made the MISTAKE of clicking -OPEN (Just once) and spent hours removing all the web browser search engines it downloaded.
I will not make that mistake again.
So, when presented with that POP-UP, always close it or (X) out of it.

So, as you can see this process is time consuming, but it MAY just highlight the As-Built data that is different and needs to be changed to enable.
My guess would be about 2-3 hours to go through all modules and research all differences

Hi, did anyone find a solution for this. I bought remote start for 2020 ranger. I am in the uk on a RHD uk ranger and it only works with the doors open. If I close all doors it refuses to work.
it seems like there should be a simple solution to this. I am begging someone if they know how to rectify this for the uk market or if there is a product that does remote start as simple as this for the uk market?

 

[airline tech]

To my knowledge - NO.
I still think it ties into the As-Built Data, something is different
The only way to help (isolate) would be to use the process I posted above and do a compare between the (UK) and (US) As-Built data.

Just to confirm - You installed Start-X? or another brand, and it connects to the Gateway Module via (T-Harness) the Gateway Module is the module where the OBD Port is, the OBD Port is on the front face and the rear connector is the (T-Harness) connection
Did the instructions include a wiring diagram? or a pic of the connector as it may be wired differently and causing the issue.
I am curious if they have the (power feed) running to Pin #24 instead of Pin #13

Pin #24 for this connector feeds power to the Gateway Module & IPC & SCCM (Steering Colum Control Module) - This would be a always hot circuit but it uses the Can Bus to trigger them on - (The Wake Circuit)
So when the door is opened (the wake circuit is triggered)
This power feed comes from the DC/DC Converter

Pin #13 - Is a direct feed off the battery and passes power though this connector and then to the front DLC (OBD) Port (Pin #16)

So basically we need to know - which of the (2) power wires is the Remote Start Module (Spliced Off of)
You can test this with a (Ohm Meter) Continuity, I am assuming that the main (T-Harness) has matching factory wiring and then the branch off (spliced) connector that feeds the Remote Start box has 4-wires (One of the wires is the Power) and we need to know, which wire that power is spliced into.

The unknown question is which wire does the US Version Use (Pin #13) or (Pin#24)
I am guessing they use Pin#13 but would need a US Version to confirm it or someone with Start-X installed to confirm.

Simple Check - With the (T-Harness) disconnected and using a meter (Ohms Scale)
Probe the (Start Box) connector and then match the (T-Harness) to Pin #13 and Pin #24
1 will show (open) and Continuity on the other.

This is just a hunch I have and we can verify, some harnesses connectors being wired incorrectly for the power feed as a possibility

 

[airline tech]

Actually it would be great knowledge to know - Start-X or (xyz) brand of how they have all the connectors pinned;
I cannot locate any information or documentation other than - Plug it in and a special sequence in the process for (lights), this would be part of the module programming.
I am looking for (SPECIFIC) wire pinouts.
The majority of that connector = Can Bus Circuits, I am curious what specific wires the Start-X and other remote start modules are wired to.
I cannot find that info, and the only way to get it = Ohm them out.

 

[zeuscraig1]

This is the simple diagram. It was fitted correctly Where the obd is located. I know this because I got the correct lighting sequence occurred, and the fact it remote starts but only with the doors open.
Now if I Installed it the exact same in a U.S Ranger I gurentee it will remote start with the doors closed.

Is your truck a manual or automatic transmission? Maybe this has something to do with your issue.

 

[zeuscraig1]

It is an automatic. I have met all the conditions for remote start etc.
Which is why it worked. But it only works with the doors open. I close the doors it doesn’t remote start

 

[airline tech]

The reason I am questioning the wiring is an attempt to pinpoint what is different and would like to start at (Step 1) the wiring pinouts.
Is your Ranger or the module (pinned) differently?
For your module and even the US Version as well as the Ford Perimeter (Plus) modules (which one of the Power wires are being used and do all modules use the same.

The reason I am questioning the Power - is that when you have the door open, the Wake Circuit has been triggered - thus the Can Bus has signaled to apply power to the GWM , IPC and SCCM.
So (this may) be the difference (IDK) I need get a confirmed power diagram from a US Version module.
More Detail: Pin #24 is always hot and feeds the IPC, when you close the door the IPC powers off.
When you open the door the IPC Partially powers up from the wake circuit.
And if wired (power-tapped) off of Pin #24 this may be the reason for it only working with the door open.
Is the US Version wired the same - ?? This is unknown

If they have it tapped to Pin #13 - then its not a power issue as this is - direct feed off the battery, however the BCM is providing the power - it does not take a Wake Signal for this power.

So we need a (Side x Side) compare of your version module & GWM connector to verify they are the same or different than the US Version Rangers

If they are identical then we need a (Side x Side) compare of the As-Built Data to find the Hex-Line that is disabling it from (sending) Remote Start signal when the doors are closed and generating a Wake Signal to the BCM / PCM via the Can-Bus

I am confident I can locate the issue but need help from others on this to provide wire pinouts from both the UK and US, as they are not within the service manuals as this is a (aftermarket) solution and I cannot locate a detailed wiring diagram for this.

I am focused more on the wiring diagram due to the (2 separate power) sources and which one of the 2 - does the US Version use and does it match yours.
Someone with Start-X or similar on here will need to check which one of the 2 the module is tapped into.
and does your GWM connector pinout match the one posted above?

I know for sure the wiring at the DLC (OBD-Port) will be the same, but that does not confirm that the GWM Connector is the same pinout - this may be wired differently - some ROW Rangers have wire pinouts that are different.

This is the diagram for my fortin remote start

 

[Superspirit]

And another that might be helpful

 

[airline tech]

Awesome Thanks So Much:

But just wanted to make sure its understood that there is a slight error on this diagram, not that it affects the Remote Start (Hook-Up) but wanted to highlight the error.

The color pic of it from the back side is also helpful.

This clarifies that they are using Pin #24 for Power and the Start Module is needing a Can Bus signal to (wake it) - that is not happening, and we just need to find the right (As-Built) setting the UK Version needs, we need to find a setting that will allow (authorize) the Start Module see that the Can Bus has sent a signal for it to wake.


Thanks Again for the awesome post and information.

 

[zeuscraig1]

Amazing work. I have tried searching but to no avail. We can use forscan to change the code. But which module and line is unknown to me.

so conclusion: there is no power coming into pin 24 when the doors are closed, but when opened, power is initiated. Reason why remote start is not working correctly.
Is the usa version built the same? If so, then it must be down to coding Within the vehicle.
sadly I think this might beat us

No, you should have a constant power on Pin #24 as its a direct feed of off the DC/DC convertor.
The Can Bus signal to all the modules on this circuit (acts as a switch) to power the modules up and shut them down (sleep-mode) when in sleep mode there is still power on the modules for memory

The DC/DC Convertor - does have a HS1 can signal to it - but it is used for Engine Status and provides power output to the - Ignition out Signal.
So power is available on Pin #24 at all times along with all the modules on the circuit.

Lets use the IPC as an example here:

The IPC provides a startup/shutdown sequence also known as a welcome/goodbye strategy. The IPC initiates and follows a progressive strategy providing increasing IPC functionality from IPC wake up to ready to drive status. This sequence begins at RKE unlock or driver door open through the ignition RUN state. During this period, the IPC provides increasing functionality from backlighting or illuminating gauge rings, gauge pointers, illuminating the PRNDS, backlighting of the message center display, displaying a message center splash screen, gauge and LED prove out, gauge sweep and finally normal IPC operation.

So with this example - everything on the circuit above is receiving a (Wake-Message) to power up. (Normal Ops) via Door Ajar or Unlock
This is how the Remote Start Module is seeing a Can Bus Message to (Wake) its following the IPC Power.

Since I am not clear as far as the remote for the remote start module:
Is it using a separate FOB and if so, do all the other functions work (door locks)?
or is it using factory remote and the Remote Module uses that frequency?

Another for all - Is this issue only for RHD Trucks? as I am not sure of this question
Another: For the affected Rangers - Do you have a Hood Ajar switch on the truck?

Anyway - The Remote Module needs to be able to receive the proper Can Bus Message that a remote start request is (requested & wake the module) then it communicates to the BCM and are all the required parameters set for the request to be commanded, if yes the BCM begins the Remote Start Sequence.

So we need to find the work around (missing link) to get the module to see a (Request) and Wake it - as when you open the door - it wakes and remote start operates normal.

The ROW Rangers have some known differences in wire pinouts but the Can Bus message should be the same - Lock & Unlock
I do not think this is the issue, I think its more getting the FOB signal to transmit on the Can-Bus when the door is closed and actually wake the circuit.

This:

The BCM activates the wake-up control circuit when a key is inserted into the ignition lock cylinder or a remote start request is received (if equipped with factory remote start). or driver door opened.

There is another instance that is not mentioned and that is the TCU, when Ford Pass checks in on the health - the Wake Circuit is triggered on the same as if you were to remote start via Ford Pass.

So the missing link is getting the Remote Module to actually communicate to the BCM (that a remote start request is (active) and provide that wake signal with the door closed.
To T-Shoot it down some:
When you attempt to remote start with the door closed, does anything at all happen?
Parking Lights Flash, Door Locks -Click or any relay power click heard?
Does the Horn Chirp?
