Default help! bmw e65 2003

I am trying to repair light module bmw e65 of 2003.

It has defects: 4 front lamps of turn signals and reverse lamps are disable. The drivers have been checked by signal injection from working channels Ė everything is normal. Drivers show information of lamps current. The multiplexors have been replaced (HEF4051). There is no output from processor to drivers of non- working channels.The diagnosability of the module is ok, it shows all troubles. At the moment of power-up there are pulses of lamps-test on the working channels from the processorís output, and accordingly there is no on non-working channels. But when connecting of accumulator on the defective outputs the momentary units are formed. Then defective outputs come to nothing and donít react upon anything. All feedings are checked-all are normal. I suspect there is a kind of down of insertion of processorís flash. Do you have the dump to this processor?



Thank you in advance, Shukhrat.
