3 Series E46 316i (M43TU) SAL
1 - Storage battery
2 - High-frequency aerial
(433.92 MHz or 315 MHz)
As of ignition lock position 1 (terminal "R"), the storage battery is charged inductively. The charging process is
realized via the ring aerial of the ignition lock and via the coiled aerial integrated in the radio transmitter. An electronic
charging unit on the printed circuit board controls the charging process.
The battery is designed for a very long service life. A prerequisite is that the radio transmitter
is used.
If radio transmitters are not used, the storage battery is discharged after approx. 18 months.
With severely discharged storage batteries, the charging period is approx. 30 hours up to maximum capacity. After
charging for approx. 30 minutes, the remote control can be actuated
approx. 15 times.
6.4 Voltage monitoring
If cell-end voltage has been reached, the central locking system, for example, can no longer be locked using the
remote control. The "Convenient closing" can no longer be used, nor can the radio transmitter be initialized.
Every time a button is actuated, the storage battery voltage in the radio transmitter is monitored. Once the storage
battery signal is contained in three consecutive telegrams, it is stored together with the corresponding radio
transmitter key number for diagnostic purposes in the general module of the central body electrics. The entry is
deleted when five consecutive radio transmitter telegrams no longer contain the storage battery signal.
In the case of E38 and E39 models, this status is already indicated by a signal in the check control.
7 System initialization
In order that the radio transmitters can communicate with the vehicle, each individual radio transmitter must be
initialized with the receiver module.
Up to four radio transmitters can be initialized and used per vehicle.
Since each radio transmitter has its own key code, all existing radio transmitters must be reinitialized when, for
example, a new radio transmitter is to be added.
Initialization procedure:
1.
Open central locking system (ZV) using the car key.
2.
Get into the car and close all doors.
3.
Using the car key, switch the ignition lock briefly to ignition lock position 1 and then switch off again. The
switching time must remain under 5 seconds, otherwise the system is not ready for initialization.
4.
At the radio transmitter: Press button 2 and hold in.
5.
Press button 1 three times (in a space of 10 seconds). Button 2 must remain held in.
6.
Release button 2.
7.
The ZV signals by means of "Locking" and immediate "Unlocking" that a radio transmitter has been successfully
initialized.
