And according to the ETM, the turn bulbs are not supervised by the external lamp monitor. At least not directly like the other bulbs. The turn signal flasher monitors the bulb current and if it doesn't have the load of 2 bulbs it flashes fast.

There is a tap to the monitor relay from the output of the flasher, maybe this is a special input to the monitor that looks for the fast flash pattern to turn on the warning light?
