you tried reprogramming/reflashing FRM3 with ISTA/P ? Most of these control units that fail have updated software available.

If after programming and encoding with ISTA/p same issue, i would recommend replacing FRM3. Not all FRM3 modules can be repaired only with bench programmer. Some have defects in flash memory.

Through ISTA+/P, one FRM block will not be able to be updated, there will be a complete update of all blocks according to plan. I wouldn't like to. Or is it possible to program only FRM through ISTA?
I can update the software in FRM3 via WinKFP

Try disconnect alarm button wires from FRM. may be problem in car (aftermarket alarm system etc.).

I wote for this
Sometimes those are surprisingly well hidden somewhere.

Hello everyone. 

I repaired FRM 3. A common problem with EEE. I considered D-Flash a programmer and with the help of the DFlashtoEEE program I got a new EEE. I wrote it down in the block and everything seemed to work.

But there is one problem.

The emergency light alarm itself turns on (turn signals). It turns on even without ignition. It works 5-6 times and turns off and after 2 minutes it turns on again and so on endlessly. ISTA sees that it is the alarm that is turned on. Error on the emergency light alarm button. The button itself does not work, the light bulb on it is lit, but it is impossible to turn off the emergency light alarm. The button was changed and it didn't help.



I will attach here a photo of the block, D-Flash, EEE faulty and EEE which I fixed and recorded in FRM3 through the programmer. 



FRM rebooted via ISTA. It helps for 5 minutes, then this problem appears. 

FRM by default encoded with an empty MAN file - did not help. 


Tell me, what could be the matter? Replacing FRM with another unit ? Maybe someone has faced such a problem. Regards

Write this and coding .....

It didn't help. Same problem. I understand that the short circuit is in the FRM3 itself

Updated FRM3 via WinKFP did not help, most likely a short circuit in the FRM3 block itself

Did you even try to read faults from it?

Of course I tried. Primarily. There are errors on the faulty emergency light alarm button. The button was changed immediately. It didn't help.
