The console between the two front seats starts behind the shifler housing. It houses the parking brake handle, optional
telephone and oddments storage tray. The rear portion of the
console houses the ashtray and covers the emergency brake
cable ends.
NOTE-
The accompanying photos illustrate a model with automatic
transmission. Manual transmission models are similar.

Central Locking and Anii-Theft
- If the starter engages, the following EWS inputs are function-
ing normally:
Ignition key
Code function
Transmission range switch or clutch position switch
Engine speed sensor
NO JE -
If a vehicle key is lost or stolen, the electronic authorization
for that key
can be cancelled using the BMW scan and di-
agnostic tools
DISplus, GTl or MoDiC.
Force applied to a ley can damage the electronic circuitry
in the key A damaged ley will not start the engine. In that
case, a new key should be purchased and initialized
by an
authorized BMW dealer.

This chapter outlines the fundamentals and equipment
requirements of On-Board Diagnostics
I1 (OBD 11) standards
as they apply to BMW vehicles. Also covered here is a listing
of BMW and OBD
I1 diagnostic trouble codes (DTCs).
ON-BOARD DIAGNOSTICS (QBD !I)
OBD II standards were developed by the SAE (Society of
Automotive Engineers) and CARB (California Air Resources
Board).
OED I1 is the second generation of on-board self-
diagnostic equipment requirements. These standards were
originally mandated for California vehicles. Since
1996 they
have been applied
toall passengervehicles sold in the United
States.
On-board diagnostic capabilities are incorporated into the
hardware and soflwareof the enginecontrol module
(ECM) to
monitor virtually every component that can affect vehicle
emissions. The
OED I1 system works to ensure that
emissions remain as clean as possible over the life of the
vehicle.
Each emission-influencing component is checked by a
diagnostic routine (called a monitor) to verify that it is
functioning properly.
If a problem or malfunction is detected,
the
diagnostic executive built into the OBD I1 system
illuminates a malfunction indicator light (MIL) on the
instrument panel.
The OBD
I1 system also stores diagnostic trouble codes
(DTCs) about the detected malfunction in the ECM so that a
repair technician can accurately find and fix the problem.

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.

DIAGNOSTIC TROUBLE CODES
(DTCs)
Below is a listing of E39 powertrain (automatic transmission
and engine)
SAE P-codes, the corresponding BMW fault
codes, and the fault code definitions.
BMW fault codes expand on the SAE sanctioned DTCs and
are accessible primarily through the BMW diagnostic scan
tool or a BMW-specific scan tool.
