Steering Wheel Switches
E46 vehicles are equipped with either
the multi-function (MFL) steering wheel
or the sports steering wheel.
Incorporated into each steering wheel
are an SRS airbag, horn contacts,
selected cellular phone and radio
controls and cruise control buttons.
To replace the steering wheel switches,
remove the airbag first. See
721
Airbag System (SRS)
.
WARNING!
Improper handling of the airbag
could cause serious injury. Store the
airbag with the horn pad facing up. If
stored facing down, accidental
deployment could propel it violently
into the air, causing injury.
CAUTION!
Special test equipment is required to
retrieve SRS fault codes, diagnose
system faults, and reset/turn off the
SRS indicator light. The SRS
indicator light will remain on until
any problem has been corrected and
the fault memory has been cleared.
