Hello Guys,

G31 get LCI tail lights.

iStep Update from 18-03 to 22-11

Add HELC to FA and coded

The car says the rear turn signals are shorted.

i try this parameters:

BL_L_CCM: ccm_346 [01 5A]

BL_L_IS_LED: nicht_aktiv, default [00]
BL_L_MIN_PWM: 5% [05]
BL_L_WARMUEBERWACHUNG: nicht_aktiv [00]
BL_R_CCM: ccm_345 [01 59]
BL_R_IS_LED: nicht_aktiv, default [00]
BL_R_MIN_PWM: 5% [05]
BL_R_WARMUEBERWACHUNG: nicht_aktiv [00]

but doesnt work.

Anyone have an idea, what i can do?

Done this several times G30 and G31. Wiring, istep update and HELC was enough every time. Check wiring one more time...

You don't need this coding. Just add helc and that's it. Like @zeronoo said check the wiring.

Check your wiring. I believe there’s an extra pin & likely change in pinning on the LCI inner taillights due to the addition of the brake light function.

Wiring was okay. HELC was added. I removed the turn signal and brake light monitoring and after that it works great.

Can you add what FDL was for that?
