Fuel Injection I
- As an alternative, harness connector housing can be sepa-
rated so that electrical
checlts can be made from backof con-
nector.
4 If replacing ECM, disconnect control module harness con-
nector (arrow) by releasing fastener and pivoting connector
up and
off ECM.
CAUTION-
Be sure ignition is OFF before disconnecting or reconnecting
DME system components.
- Remove ECM from retaining brackets and lift off holder.
- Installation is reverse of removal.
- Before attempting to start engine, use BMW service tester
DISplus, MoDiC, GTI or equivalent:
- Code replacement ECM with application information (i.e.
engine code, transmission type, etc.).
Align ECM to EWS (electronic immobilizer).
Siemens MS 41.1 ECM pin assignments
ECM pin assignments are given in Table b. For engine man-
agement system schematics, see ELE Electrical Wiring
Di-
agrams.
CAUTION-
a Always wait at least one minute after turning off the ignition
before removing the connector from the
ECM. If the con-
nector is removed before this time, residual power
in the
system relay may damage the
ECM.
Always connect or disconnect the control module con-
nector and meter probes with the ignition
off
When malting checks at the ECM itself, a breakout box
should be used to allow tests to be made with the connector
attached to the ECM. This also prevents damage to the small
terminals in the connector. As an alternative, the harness
connector housing can be separated so that electrical checlts
can be made from the back of the connector.

1 Central Locking and Anti-Theft
NOJE-
A single unlock request from the driver's door with the FZV
key unlocks the driver's door only.
A second unlock request
unlocls the remaining doors and trunk. This feature can be
modified for individual users with the Key Memory capabil-
ities to activate all lock actuators simultaneously See Car
Memory
/ Key Memory later in this section.
Starting with 2000 models, the battery in the FZV ignition
Icey is recharged by the ignition switch ring antenna while
the ley is in the ignition switch.
Transmitter self-test (models to
1999)
Press buttons 1 and 2 at the same time. This starts ltey trans-

If batteries are replaced within one minute of removal, it is
not necessary to

Tlie state of charge of key batteries has no effect on elec-

batteries.
The state of charge of key transmitter batteries is monitored
by the
GM. Once the voltage level of the transmitter drops be-
low
4.5volts, the LED no longersignals transmitteroperation.
Convenience opening, initialization and self-testing are no
