BMW F10 LED Blinker Not turning on.

JohnnyMozzarella · 10-14-2021, 10:40 AM

All,

Does anybody know where the power comes from on the LEFT LED turn signal on an F10 series BMW? My LED blinker is out and I've replaced the LED Module as well as the TMS module. The side blinker works fine. I know there is some corrosion on the TMS module connector inside the blinker, but is that where the power comes for the LED blinker only? I have Xenon headlamps.

I know I have to program the TMS module then do the adaptation learning resets, but I dont think the TMS module withholds power to the LED Blinker. Makes me think the connector to the TMS module is messed up since there is corrosion on the connector inside unless there is some fuse that is out.

BLUF - left LED Blink is not getting power nor blinking.

1. already swapped TMS module
2. already swapped LED blinker module
3. I think its the ballast OR the TMS Module connector (where ever power comes from)
4. Could it be a fuse somewhere? I dont know where those fuses are?
- still no power or blinking on the LED Module

There is no LED module as far as I'm aware, just the TMS and ballast

If you did swap the TMS, you'll need to VO code it to the car via Esys and then initialize it through ISTA.

If you have had a short in your side marker LED, and that short has exceeded a certain count tracked by the FRM (footwell module), you'll need to run ISTA to reset the counter.

The power to your left headlight assembly (E86) is provided to your headlight assembly connector E86*1B, via pin 5 from Fuse 30F on fuse panel Z3, in the rear trunk.

The side marker is controlled via the LIN Bus from the FRM, which is on E86*1B, pin 8, (white/red stripe wire) separate from the low/hi beam signal from the FRM, which is on E86*1B, pin 6 (white/purple stripe wire).
