This Service Information bulletin supersedes SI B65 36 09 dated November 2009. [NEW] designates changes to this revision
SUBJECT
Airbag Warning Lamp Illuminated, FC 93D2
MODEL
E82, E88 (1 Series)
E90, E91, E92, E93 (3 Series) E70 (X5)
E71 (X6)
Vehicles up to 9/2009 SITUATION
The airbag warning lamp is illuminated and fault code 93D2 (Passenger Off Lamp [POL]) is stored in the fault memory. No other airbag system fault is stored.
The diagnosis test plan indicates that there is either a wiring fault, or the POL is defective. The ACSM (Active Crash Safety Module) or MRS5 (Multiple Restraint System) control module will not cause this fault, but warranty records indicate that they are unnecessarily being replaced for this fault.
CAUSE
E82, E88, E90, E91, E92 and E93: Software error in the FZD (Roof Functions Center) E70 and E71: Bad connection at the FZD
CORRECTION
For the E82, E88, E90, E91, E92 and E93, program the vehicle using ISTA/P 2.35.0 or later.
Note that ISTA/P will automatically reprogram and code all programmable control modules that do not have the latest software.
For information on programming and coding with ISTA/P, refer to Centenet / Aftersales Portal / Service / Workshop Technology / Vehicle Programming.
For the E70 and E71, repair the bad connection at the FZD (most likely, the connector is not pushed in fully).
