Exchange of airbag control unit
E31, E34, E36 US
Situation:
The following fault may be entered in the fault memory after the airbag control unit with the
part number 65 77 8 369 828 has been fitted: "Seat-belt switch, driver or passenger -
Coding data does not match up with vehicle equipment". This fault cannot be cleared. This
fault entry is caused by the following conditions:
1.
The airbag control unit fitted beforehand had the part number
65 77 8 352 763 (no longer available from the Parts department).
2.
The lock contact of the seat belt or the seat-occupancy detector (SBE) has been
mistakenly connected to the vehicle wiring harness when a seat-belt lock has been
replaced at some previous time.
Technical background: In contrast to the old control unit, the new one checks the
connection between the seat-belt-lock contact and seat-occupany detector (SBE). The
plausibility check using the Central Encoding Key (ZCS) leads to the above-mentioned fault
entry, because the above pieces of equipment, namely "seat-belt-lock contact/SBE", are
not stored in the ZCS for the vehicles in question.
