Headlight TMS errors, help please
I am getting errors 8041F0 and 8041FF
Driver/Right headlight driver module (TMS): Coding error How do I go about fixing this in E-sys? Or do I need something else? This was after doing a halogen to xenon retrofit. My BMW dealer says the modules and wiring is fine as they are communicating, but they cannot do any intializing for the TMS unless they recode, which will then wipe my xenon VO retrofit... Is there a way to code them properly in e-sys, or do I need something like rheingold/ista+? |

Then coded the LWR out. Still getting the same error... Last edited by wings516; 01-19-2021 at 07:39 PM.. |

I did not... I have not seen any writeups about the ICM. I currently do not have the height/vertical sensors installed, so I have disabled LWR in the FEM module.
Is that in ESYS? Same procedure as FEM Cafd? Thank you again for your help. Last edited by wings516; 01-20-2021 at 09:28 AM.. |

But you only have to activate the VO, mark the ICM (or ICMQL) and Hit the button „Code“. Please do not scare. There are many error messages in the car after coding, but they disappear after the ignition is switched off / on. In the ICM is 1 value which differs between Xenon and Halogen. |

When you say there is 1 value that differs between Xenon and Halogen in the ICM, do I need to FDL code that inside of there? Or will the CAFD flash take care of that? Thanks |

Flash is the wrong word for that.
Flash would mean an software update. But you only need to code these 2 ecus. With the CAFD was a mistake from me, because i thought the TMS is a new ecu and appears in the ecu tree. But i read that the TMS will be coded together when the FEM will be coded. So the FEM or ICM don‘t need a new CAFD. You only have to activate the changed VO and Code (Button „Code“) these 2 ecus. No need to FDL Code something, because this 1 value will be changed by coding the ICM. |

Here i found some hints that sometimes a new FEM is needed.
https://f30.bimmerpost.com/forums/sh...808444&page=14 The VIN will be transfered by coding, so i think that‘s no problem. |

Plenty of people have done this with success, so I must be missing something... ISTA clearly is pissed about the FEM not being encoded, but I have done a new CAFD code on it three times now... The folder turns rainbow after I do it. I'm wondering if I am missing something there as well... |

The problem here, however, is that there seem to be cars in which the TMS modules can be seen and coded directly in E-Sys, and with some models these do not exist, even if they have Xenon. My old F30 (built 2014) also had Xenon, but I don't see any TMS modules when I call up the data from earlier. That's exactly what I don't understand until now. In the meantime, however, you can check whether the values have been set correctly. E.g. in the FEM the value "XENON_OUTPUT_L" and "XENON_OUTPUT_R" should set on "output_channel" after coding. And in the ICM the value "IcmKod_I_HSS_Connect" should be "05_Xenon_or_IAS". |

I am trying to run ISTA P now and I am getting this error... Not sure what to do about this and not much info online. I was going to try and encode the FEM through this, but I'm hitting another wall. |

Are you sure you installed xenon and not led? From my understanding xenon you won't see tms modules in ecu tree. The only times I've ever seen initialization prompt and tms codes was for led headlights not xenon.

Do you have to VO code these extra modules or should they automatically appear after VO Coding 522/524? Last edited by wings516; 01-21-2021 at 07:16 AM.. |
