2018 gauge cluster retrofit

[Sherrodmustang]

Tasca is saying it is on backorder now...

Not sure what is going on, they said it was at the warehouse last week.

Now they have my money tied up also.. it hasn't been refunded to my card as of yet.

Also they are saying no ETA from Ford on the part.

So, seeing as to how you are able to install the Digital Dash Cluster into the 2015-2017's, I've been curious about the modules in the 2018's (and since I have a new 2018 myself). So I went to the Ford ETIS site, registered and input my VIN. I then went to the "Vehicle Software" tab, and the returned results displayed a list all of the modules installed on my 2018 (attached image here).

Maybe this listing will help others too.

I'm posting this list here to see if the listed modules already installed into a 2018 S550 are what is needed to be present in order to swap in a Digital Dash Cluster into a 2018 - or if some of these already existing modules would also need to be replaced. I hope I'm stating that in the correct manner....

[MENTION=13960]Cobra Jet[/MENTION] you don't need to replace any modules except for the instrument cluster itself. Please view the thread here for the installation guide: https://www.mustang6g.com/forums/showthread.php?t=99275

ALL. I currently have a 72 hour subscription to Ford Service Info so if you need ANYTHING please ask so I can save it as a PDF for you. I saved the ENTIRE 2018 Mustang wiring diagram book. Took me like 3 hours lol. Not quite done with the connector views yet.

I pulled the info to compare high beams on the 2016 and 2018. Here are the differences.

2018:
High Beams
The SCCM monitors the LH steering column multifunction switch for a high beam request. When the LH
steering column multifunction switch is in the HIGH BEAMS position, the SCCM sends a message over the
HS-CAN2 to the GWM then the GWM sends the message to the BCM over the HS-CAN1.
When the low beams are on and the BCM receives a request for high beams the low beam Light Emitting
Diodes (LEDs) remain powered on and the high beam Light Emitting Diodes (LEDs) within each headlamp are
activated. This changes the headlamp beam intensity to illuminate a greater distance.
The BCM supplies a high current switched voltage to the headlamp assemblies to supply the necessary
current to operate the high beam Light Emitting Diodes (LEDs).
The BCM also provides an Field Effect Transistor (FET) protection of the high beam output circuits. When an
excessive current draw is detected, the BCM disables the affected circuit driver.


2016:
High Beams
The SCCM monitors the LH steering column multifunction switch for a high beam request. When the LH
steering column multifunction switch is in the HIGH BEAMS position, the SCCM sends a message over the
HS-CAN2 to the GWM then the GWM sends the message to the BCM over the HS-CAN1.
When the low beams are on and the BCM receives a request for high beams, the High Intensity Discharge
(HID) bulbs remains powered on and the shutter within each headlamp are activated. This changes the
headlamp beam pattern to illuminate a greater distance.
The BCM supplies a high current switched voltage to the headlamp assemblies to supply the necessary
current to operate the high beam shutters.
The BCM also provides an Field Effect Transistor (FET) protection of the exterior lamps switched voltage and
high beam output circuits. When an excessive current draw is detected, the BCM disables the affected circuit
driver.


Looks like it is extremely similar except the 2018's DO have two LEDs for high beams vs just one for low... So the message from the SCCM to BCM must be different in 2016 vs 2018. Weird that flash to pass works or it stays on holding it...

And we fix this how, lol?? :shrug:

Good job breaking that down.

 

[breeves002]

I wish I knew.... We'll see what the others say... My mind is going crazy at this point and I need a break lol.

Well just a thought:

Could it be the GWM causing trouble here?
I mean obviously the BCM is still able to activate the shutters in the headlamps (flash to pass). It just doesn’t get the high beams command right. All of those commands are being received by the GWM over the HS2 to be sent down the HS1 CAN. So the GWM is part of the command chain, too.
What if the old (pre 2018) GWM is not able to distinguish between the “flash to pass” command and the “high beams” on command coming from the new (2018+) SCCM?

I know that messing with the GWM is a bit risky since it’s the central module for all CAN-BUS ops but to me it still doesn’t sound like the problem is to be found in the BCM.

I’d put my money on GWM or SCCM or a combination of both.

There is no ABD difference between the two GWMs but I wonder if there is a firmware difference. :shrug:

 

[buzz-dee]

You’re right. The as-built is identical across the MY’s. However the part numbers and software versions differ:

2015 part# FR3T-14F642-AD Calibration FR3T-14F530-AD
2018 part# JR3T-14F642-AE Calibration JR3T-14F530-AE

Would that mean the newer firmware would work for any year? If it didn't having the same part number sounds like an invitation to screw ups.

Typically yes... I have a 2014 Fusion and I flashed my GWM to that of a 2018 fusion due to all the module mods and upgrades I tend to do... the GWM is the exact same across the board. Just the firmware is different... newer year firmwares can understand newer CAN bus messages. The GWM is basically the network router of the car.

2 of us ordered the part a couple days ago and will keep you guys updated if they work (the GWM).

 

[db252]

I’m the other guy who bought the GWM, not necessarily for the brights which would be awesome if it does fix that, but for activation of the heated steering wheel via the sync3 touch screen. I have all my other parameters configured and I know the wiring is correct because when I do a heated steering wheel module test through forscan, the wheel gets warm. It just won’t activate the switch and coincidently this goes through the GWM also.

My 18 GWM ‘should’ be here today and I will update the situation when I know.

 

[breeves002]

Db252 and I were talking about this when troubleshooting the HSW and we came to the conclusion a GWM is the likely reason the HSWM is never seeing the message from the APIM or FCIM or wherever it comes from (pretty sure APIM). I'm hopeful this will work.

However I DO NOT think it will solve the high beams issue. We'll see, but I really think thats a BCM problem. Since you can press the high beam stalk into the high beams location and they'll stay on as long as you press it either direction (forwards or flash to pass). I would be very happy if a GWM was the fix for this because it really is a cheap and easy fix.

As I'm thinking more its possible the SCCM is sending a new type of message that the GWM just interprets as a flash to pass message... That would be pretty interesting... Man I'm really hoping this works.

Can I do a little dance? (it was a guess on my part, but an educated one)

It is a current issue. :cheers:

On the 2018 equipment it is looking for a higher current draw through the LEDs to know the high beams are on. If that current draw doesn't happen the system thinks the high beams are not working. I think the CAN message for "High Beam Command" is a standard one, so it will be common on both style headlamps. However, the message for "High Beams Active" is not standard for both types of headlamps or it is proprietary and non-standard.

The only remedy I can think of is maybe swapping for 2018 headlamps if they fit...? :shrug:
