Hi,
I have an E60 530D with AHL but the AHL dosn't work. The headlights won't even do the self test when you turn you car on. I checked the connections to the SMC modules and they are good. So i figured i'll try to look at the coding and see if a problem exists there but when i try to read RSMC and LSMC via NCS i get an error.


Does this mean that both my SMC are fried? Or NCS just can't communicate with those ECUs and i have to use some other program.

I also get two faults.

No. This means the LM is fried.
Had the same problem.

You need a new LM.

But my lights work. So does it mean there is some specific chip that has gone bad on the LM?

C_o_s_m_i_n

Yes. It burned out only the communication part between the LM main processor and the ALC modules form the headlights.

I see. Thnx.
