For those new to this stuff: 4 Ways To Get Rid of Hyper Flash For LED Turn Signal Lights

I chose the 3rd option, as the turn signal circuitry in the Innova is still the 'old school' type that uses a discrete flasher relay separate from the on-board computers.

The fourth option, the one which the OP mentioned, will only work on certain cars and will require the necessary software that allows you to change computer parameters. That is, if the particular car supports the command. The aftermarket bluetooth OBD2 pluggables will typically only allow you to read realtime values, extract DTCs, and reset DTCs. It typically won't let you change anything.

May I ask where you've got the LED flasher relay? I have a 2018 Innova. Though I wonder if it also uses the same type of flasher relay as the old Innova, I still want to know where to get the flasher relay. Thanks!
