Understood, but is anyone able to confirm the Hazards use the TSM or not?
or does anyone have a better circuit diagram that shows the hazard components?
Welcome to the world of TSM failure...
The TSM can give a whole host of weird faults and so best just get a new one and plug it in and see if it works.
The hazard unit (red or orange relay) is an easy to obtain item but I would go with TSM first...
Good luck with the fault diagnosis.
And unfortunately there is no other schematic/wiring diagram available so your stuck with the one in the parts book....
