The TSM does a lot more than that. When it goes wrong all sorts of strange things happen such as the engine running all the time with ignition off, or not at all, along with random hazard lights. It is a sort of CAN bus rather than just a relay switch box.
I certainly had the uncommanded hazard light issue a couple of times although it occurred randomly and not repeatable. Regarding the TSM unit affecting the engine, clearly not by design but likely to be a back feed from some "keep alive" power source, side or hazard lights maybe.
Mogegg, I note you still have the headlight main beam issue. Did you try changing/swapping the low/high beam relay as I suggested in another thread? To reiterate there are two relays controlling high beam, one for flashing and second to latch high or low beam.
