How to trigger Secondary Bootloader
Posted: Mon Feb 16, 2026 1:09 am
I have fitted a 2021 Mustang Mach-e powertrain to my1965 Ford Falcon . I amusing v2.3.70 with a valid Extended License and a OBD Link/ Kvaser interface.
I am unable to write to the GWM (Gateway Module A) at address 716-01-01 The "Write" button is missing and the software does not trigger a Secondary Bootloader (SBL) download, even when connected to the internet.
I need to change716-01-01 (Airbag /RCM Presence) to "Not Fitted" to clear network faults.
Can anyone please provide a Test Build or specific SBL files to unlock the writing for this GWM strategy?
Thankyou for your help with this build!
