Air supply unit, removing and installing
CAUTION-
Maintain high levels of cleanliness around air line connec-
tions when disassembling and assembling air suspension
components. Even small dirt particles can cause
leakage in
the pressurized system.
When the airsupply unit is removed for any reason, reset ride
height using BMW scan tools DIS or
MoDiC.
- Remove spare tire.

Tilt sensor operation:
1. DWA armed, vehicle level. Tilt sensor sends HlGH sig-
nal to General Module (GM).
2. DWA armed, vehicle tilted. The fluid moves in sensor,
changing resistance value.
HlGH signal changes to
LOW signal. GM activates alarm.
If the vehicle is jacked up or lifted in any way, the angle of the
liquid changes, producing a change in the resistance value.
The sensor signals the GM to activate the DWA alarm. The
sensor resets at the new angle.
This allows the DWA system
to remain armed and to reactivate the alarm if tlie vehicle is
moved again
Locking the vehicle twice within a few seconds will deactivate
the tilt alarm sensor while arming tlie remainder of the sys-
tem. This allows the vehicle to be transported in an armed
state without activating tlie alarm.
Interior protection
The interior motion sensor is mounted in the center of the
headliner panel. Due to the design of the vehicle interior, the
sensor must be installed in the correct direction to ensure
proper operation of the system.
lnterior sensor FIS (1997 - 1999 models)
4 When the alarm system is armed, the FIS sensor emits elec-
tromagnetic waves at
a frequency of 2.45 GHz. As long as
nothing is moving in the vehicle, the waves are reflected
baclc
to the sensor at the same frequency. If a foreign object enters
the vehicle, the frequency of the reflected signal changes.
The sensor detects the changed frequency and triggers the
alarm.
Every time the DWA system is armed, the sensor adapts to
whatever objects might be stationary in the interior. This al-
lows pacltages or objects to be left inside tlie car without ef-
fecting the operation of the system. The sensitivity of the
sensor is set so that the moving object must be at least as
large as a bumble bee. This prevents a false alarm from oc-
curring if a small insect is caught in the vehicle.
FIS is switched off when the vehicle is locked two times within
ten seconds. The DWA LED will flash one time for confirma-
tion. This allows the sensor to be switched off to avoid false
alarms when the windows are left open for venting.

Airbaq System ~SRS)~
4 Sport steering wheel:
Insert screwdriver through opening in rear of steering
wheel and push against spring tension to release
airbag
unit lock.
Repeat procedure on other side of steering wheel.
Lift off
airbag unit and detach electrical harness connec-
tors.
WARNING-
Store the removedairbag unit with the horn pad facing up.
If stored facing down, accidental deployment could propel
it violently into the air, causing injury.
Once an
airbag is removed, the car must not be driven.
Do not connect the battery with the
airbag disconnect-
ed. A fault code will be stored, setting off the
airbag in-
dicator light Special tools are needed to reset the fault
memory
Once the
airbag unit is installed and all other service
procedures have been completed, start the engine and
check that the
airbag indicator light goes out. If the in-
dicator light stays on, the
airbag system will not func-
tion as designed. Have the system diagnosed and
repaired by an authorized
BMW dealer.
- Installation is reverse of removal.
MFL steering wheel: Torque airbag using specification list-
ed below.
- Sport steering wheel: Press airbag unit mounting pins into
spring
loclts in steering wheel until they snap in firmly.
CAUTION--
Do notpinch airbag harness in center of steering wheel when
installino

- Disconnect negative (-) cable from battery and cover nega-
tive terminal with insulating material.

OED-2
On-Board Diagnostics
Specialized OED II scan tool equipment is needed to access
the fault memory and
OED I1 data.
The extra hardware needed to operate the OED
I1 system
consists mainly of the following:
* Additional oxygen sensors downstream of the catalytic
converters.
Fuel tank pressure sensor and device to pressurize
fuel
storage system.
Several engine and performance monitoring devices
Standardized 16-pin
OED II connector under the
dashboard.
Upgraded components for the federally required reliability
mandate.
Malfunction indicator light (MIL)
OED II software illuminates the malfunction indicator light
(MIL) when emission levels exceed 1.5 times Federal
standards.
4 For E34 cars covered by this manual, three different MIL
symbols were used, depending on year and model.
MIL illuminates under the following conditions:
Engine management system fault detected for
two
consecutive OED iI drive cycles. See Drive cycle in this
repair group.
- Catalyst damaging fault detected.
Component malfunction causes emissions to exceed 1.5
times OED
II standards.
Manufacturer-defined specifications exceeded. Implausible input signal.
Misfire
faults.
Leak in evaporative system,
Oxygen sensors observe no purge
flow from purge valve 1
evaporative system.
ECM fails to enter closed-loop operation within specified
time.
ECM or automatic transmission control
module (TCM) in
"limp home" mode.
ignition key ON before cranking (bulb
check function).
OED
II fault memory (including the MIL) can only be reset
using a special scan tool. Removing the connector from the
ECM or disconnecting the battery does not erase the fault
memory.
