Appreciation to @markfm for the heads-up on this, since it has not yet been posted to Ford's Professional Technician System (PTS) website.

Haz, how does a dealer see it then?

The Program was announced today on PTS...

Haz, can you elaborate on what the TRON does?

This is the first reference to Trusted Real-Time Operating Network (TRON) that I've seen.

 

I'm aware that an update to the Ford Diagnosis and Repair System (FDRS) was recently released. so TRON may be a new app running within FDRS used to perform certain tasks.

 

The name suggests that it facilitates communication, so hopefully, FDRS diagnostics and module updates have been improved.

 

Good luck!

Ford has issued CSB 24B54 Supplement #1 to Dealers, with a revised date for Owner Letter mailing...

 

 

...increases the allowable Labor Time to conduct the Service Procedure...

 

 

...and revises the Service Procedure to improve the programming success rate.

 

The updated Service Procedure with revised instructions shown in red text, formulated for dealership professional technicians using the Ford Diagnosis and Repair System (FDRS) to perform the software updates, is attached below as a PDF document...

 

Owners who opt to perform the software updates on their own, will use the Over The Air (OTA) automatic download and installation method.

 

In Canada, the only Supplement #1 difference is Canadian Owner Letters are expected to be mailed by mid-December 2024.

Thanks for update.   How on earth do they think the OTA is possible when you look at all the conditions (SOC, battery voltage, profile mode, etc)?  If OTA was so much better, why not do it that way at the dealer?   They should be able to force an update through secret commands.

 

I watched a tech try to do it mobile and it looked primitive. = downloaded to tool, build USB key, then insert in car USB and then start update. In my case, it failed to recogize the key and the tech stopped. I considered that as a blessing.  He was able to get window fix and the GWN done but balked on the APIM.

 

I have noticed it takes MINUTES for the vehicle to recognize a USB key (like a music USB),

Trusted Real-Time Operation Network (TRON) - System Operation and Component Description

Overview

Trusted Real-Time Operation Network (TRON) is a cyber security protocol applied to certain modules connected to the vehicle communication networks. This protocol provides a digital message authentication for data being communicated between modules on the networks, to make sure the data received by a module is the data sent by the sending module and has not been interrupted or tampered with by an outside source.

 

Trusted Real-Time Operation Network (TRON)

Trusted Real-Time Operation Network (TRON) secret data authentication security keys are applied to modules with motion control, safety critical and security critical functions. Not all modules on the vehicle will have data authentication security keys applied. The secret authentication security keys provide a digital data handshake between the sending module and the receiving module to confirm the data received has been sent by the expected source.

 

The initial secret authentication security key distribution takes place at the end of the production line, prior to the vehicle release to the dealer. The key update mechanism includes a key management client and key management server modules. The key management client is the GWM and the key management server modules are the modules participating in the TRON function. The GWM generates the keys and distributes them to itself and the server modules, one module at a time sequentially. The keys are processed by the receiving modules and stored in their memory and a backup of the distributed keys is stored in the TCU . After the vehicle's TRON has been successfully configured, the production line end of line tool sends a copy to the Ford backend data systems for storage.

 

If a TRON-capable module is replaced, the module secret authentication security key must be applied to the new module so it functions on the network when installed. When replacing a TRON capable module, run the FDRS Trusted Real-Time Operation Network (TRON) Module Authentication Diagnosis and Repair procedure to distribute a new set of secret authentication security keys to all TRON-capable modules.

 

The GWM and the TRON capable modules can set Diagnostic Trouble Codes (DTCs) if the keys are misaligned between modules, there are communication issues on the vehicle network or a module is not responding.

 

 

Component Description

Gateway Module

The GWM acts as the key management client for the Trusted Real-Time Operation Network (TRON) system for creating, monitoring and distributing the secret keys to the participating modules.

 

Telematic Control Unit Module

The TCU stores a backup of all Trusted Real-Time Operation Network (TRON) distributed keys.
