There is no bi-metal flasher. The turn signal lamps are directly driven by the BCM. See EXL-82 of 2009 FSM.

The BCM monitors current flow to the lamps and goes into fast-blink mode if the current draw is too low. See EXL-15 of 2009 FSM.

The rear turn signal lamps are on separate BCM outputs. The side and front lamps are in parallel with each side on a separate output. See EXL-82 of 2009 FSM.
