OEM LED Tails not working with adapter cables?

[playmakr88]

Hey Guys,

I recently purchased a set of OEM Tails from a '05 325ci . My Car is an '03 M3 (10/02 build date). I also purchased Tail Light adapter set PN#61120153650 from FCP Euro. The OEM Tails are not providing any type of light output; turn signal, brake, etc.

I used NCS Expert to add "+LEDH" to the VO and did a "FA_WRITE on both AKMB and ALSZ. I even performed a SG_CODIEREN on the ALSZ to reset the LCM to defaults.

Has anyone seen/experienced this? No light output at all?

When I plug in my old lights, they work just fine.

You did not thoroughly look over the adapters. The adapter set is labeled left and right side. You have them mixed. The light will not function until you fix this.
