What to check next
Diagnostic guidance. Suggested checks and possible repairs are separate from the owner's reported results.
Compare the left and right exterior signal lamps and document any missing or dim function. Verify the specified bulbs and inspect the affected sockets and wiring before considering another switch or control module.

Does this car have LED's or has the bulbs been replaced with LED's? If the bulbs have been replaced with aftermarket LED's this is your problem. You must have the correct bulbs to supply the correct resistance or the blinkers will cycle to quick. I would replace the bulbs at the both the front and rear even if they work. I have seen bulbs work even though the resistance is off. Please let me know.

If the bulbs are working replace them anyway. The BCM controls the bulb operation and if the resistance is wrong they will blink to fast. This can can tell you more.

Hi guys. One more thing to consider that I've run into a few times is a non-working bulb that isn't recognized. This almost always happens in the rear. There can be two or even three bulbs in one rear corner, and they may have two filaments in each one, one for the tail light that still works, and one for the brake / signal that is dead. To check for that, use the hazard flasher so both sides flash at the same time, then they're easy to compare if both sides look the same.

Discussion summary
turn signal hyper flash?
The right-front turn signal flashed rapidly despite bulb and turn-signal-lever replacement. The owner confirmed standard bulbs rather than LEDs. Contributors suggested checking bulb specification and whether every signal filament was operating.
Reported outcome: No inspection results or successful repair were reported.
The thread does not confirm the installed bulb specifications or identify a failed socket, wire or module. A bulb that illuminates is not a complete functional comparison of all signal lamps.
