HI mates,
I have a Merc C220 in the workshop with airbag light on. Scanned with diag and shows about 7 faults: one of them is 2/2 for faulty srs ecu. Tried clearing thru diag with no luck, codes are still current. Simulated some of the faulty component codes with resistors and still same current faults come up. This makes me think that the srs derm has exceeded its limit for crashes or its dump is corrupt. Tried reading with UPA two ways:
as MC68HC11E9 and E9-old. The MCU mask is E28B.
There are 2 MCU's on the board, however, so I am not sure which one to read, so I read the easier one to get to. I attached both crash dumps for E9 and E9-old.
Can someone have a look and see which one is the proper one and help me clear it.
SRS p/N: (000-820-81-26). Not
sure of the Bosh number because someone took off the sticker.
Thanx in advance:top:
