Hello everyone,

I want to change the rear light from my 2018 Insignia B to Buick Regal MY 21(china) full led.

In the model from Insignia B/Buick Regal from 2018 to 2020 is the the brake and tail light led but turn, backup and fog are standard Bulb.

The "new" 2021 -2024 buick china have full led.

Dose anyone have successfully disabled the bulb check in the bcm?

Very King regards 😀

if the bcm its the same, should be possible.

have you a vin?

The BCM from my bcm i have. InsigniaB_MY18.zip

But to find a vin from buick regal china i was unsuccessful.

It very hard to find any useful data oder information.

Hi. Yes, the check can be disabled. I did this on a Buick using Calibration 7. What is your car's VIN?

From Insignia 2018 W0VZX6ECXJ1099744

Hi. I don't have BCM cals from chinese Regal. But I can find chinese VIN and check cals in TIS.

You need to use this one calibration:

If you need VIN and you can download calibrations for it I can send it to you.
