EXCERPT:
Closed-circuit (standby) current cutout
The electrical closed circuit cutout function switches off loads which consume closed circuit (standby) current at terminal 30. The closed circuit current cutout is controlled by the load cutout relay K72.
A voltage filter is additionally integrated in the relay K72 to filter the ripple of the electrical system. This filter is necessary for the motors of the steering column and seat memory.
The following systems are connected to the closed circuit current cutout:
•7 series, E38, up to model year 1996: Seat adjustment, rear head restraint adjustment, steering column adjustment and sun shade.
•7 series, E38, as of model year 1996: Seat/steering column memory
•5 Series, E39: Seat/steering column memory
The relay K72 is driven via terminal 15 and the "load cutout" signal from the general module of the ZKE III
Load cut-out signal
The load cutout signal is switched by the general module of the ZKE III.
When terminal R is switched on, B+ is switched from the general module to the relay K72. The general module switches off the B+ supply 16 minutes after switching off terminal R.
The relay is switched on again together with switching on terminal R or terminal 15 or, when a signal change takes place at an input of the ZKE III; e.g. opening a door, opening the front lid, unlocking a door.
When terminal 15 is switched on (signal at Pin 8 of relay K72) the closed circuit current cutout relay switches on the B+ supply for the connected loads irrespective of the status of the load cutout signal.

Symptom list in the case of complaints regarding the audio system
This symptom list contains radio complaints which are not caused by device malfunctions. Replacing the radio will not eliminate the problem.
Reception
Poor reception with radio BMW Business CD RDS (world device CD 43)
Cause: Incorrect reception area set.
Radios concerned: Business CD RDS (world set CD 43)
Situation: The Business radio CD RDS (world device CD43) is designed for all reception areas in the world. If the right reception area is not set in the radio menu ”AREA”, the result can be poor reception.
Action: Setting the reception area
Procedure: Initial commissioning of the radio (replacement device, new device)
•Fit replacement radio in vehicle and switch on radio.
•The message ”NO AREA” appears in the radio display (only during initial operation of the radio)
•Now switch to the required region (”Europe”, ”USA”, ”Canada”, ”OC+RDS”, ”Japan”).
a) On E46 radio and DIN unit with ”Station button 1”.
b) On E39 radio with first softkey (Station button 1).
•Now switch off radio (AREA is saved).
Procedure: Changing a reception area that has already been set
a) On E46 and E39 radios
•Switch on service mode (switch on radio and press ”m” button within 8 seconds)
•Now press the ”+ button” as many times as required until ”AREA” is displayed in the radio display.
•Use ”Station button 1” now to select the suitable AREA in the menu and switch off the radio (AREA is stored).
b) On DIN radio
Same procedure as for E46, E39 radio
On the DIN radio, depending on the set reception area, a CODE input might be necessary after the changeover.
Temporary reception cutout
Cause: Radio searches for better alternative frequency in the reception chain. Here the received station has to be interrupted briefly, which leads to gaps in reception.
Radios concerned: Reverse and Business
Note: RDS may be switched off in critical areas. In the case of the ”Professional” radio this search for alternative frequencies is carried out with a second receiver. This is the reason that there is no temporary cutout with this radio.
Temporary reception fall-off, lattice fence effect
Cause: Multipath reception fall-off - concept-related on VHF - multipath cancellation effect due to wave overlay.
Radios concerned: Reverse or if no aerial diversity is fitted.
Note: Can be remedied using aerial diversity (only in conjunction with Business and Professional)
Interference noise or crackle on classical music stations
Cause: Classical music stations often broadcast with low modulation in order to avoid distortion. As a result, interference is distinctly more discernible.
Radios concerned: All
Note: No corrective measures possible as the fault is caused by the broadcasting station.
RDS
The radio does not set better alternative frequencies on the stations stored under the station buttons.
Cause: Frequencies have been stored before the station name appears in the display or the station has no alternative frequencies.
Radios concerned: All
Note: When storing the station, wait until the station name appears in the display.
Radio does not set an alternative, better frequency. Only the frequency appears in the display.
Cause: RDS is switched off.
Radios concerned: All
Note: By pressing the RDS button, the station name appears in the display and a search is conducted automatically for the best alternative frequency.
In certain areas no alternative frequencies are found although they can be set with a manual search.
Cause: In areas that have stations with permanent regionalization, alternative frequencies cannot be found when regional mode is switched on (REG=ON) if they have another regional identifier.
Radios concerned: All
Note: REG by pressing the RDS button for a longer period (display: REG=OFF) or switch off the REG button.
Receiver jumps of its own accord to another station (or several other stations)
Cause: The regional station function is switched off in the radio and the station being listened to broadcasts regional programs.
Radios concerned: All
Note: REG by pressing the RDS button for a longer period (display: REG=OFF) or switch on the REG button.
Traffic information
Radio increases the volume of its own accord or following traffic information it no longer reverts to normal volume.
Cause: The station has forgotten to reset the traffic information identifier (TA) (common occurrence with private stations).
Radios concerned: All
Note: The old status can be restored by switching off the traffic information function (press TP).
The volume of traffic information increases several seconds before the actual message is received.
Cause: The station often broadcasts the traffic information identifier (TA) too early (a common practice in order to broadcast the time for traffic information memory).
Radios concerned: All
Note: No remedy; caused by the station.
Traffic information volume too loud
Cause: The traffic information volume can be varied during the announcement. The set volume is stored automatically.
Radios concerned: Business and Professional.
Note: During traffic report, set volume lower.
Minimum setting of traffic information volume too loud or too quiet.
Cause: Basic traffic information volume set too loud or too quiet.
Radios concerned: All
Note: Adapt basic volume as part of diagnosis procedure or in service mode.
Cassette / CD operation
Cassette playback too fast or too slow
Cause: Cassette has been recorded on a home unit with another speed (too slow or too fast)
Radios concerned: All
Note: Check playback using other cassettes.
During the music track search, the cassette does not stop between the tracks.
Cause: The breaks between the tracks are too short.
Radios concerned: All
Note: For the music track search, there must be breaks between the tracks of at least 4 seconds.
Cassette / CD operation is interrupted by the radio; unable to return to the cassette / CD operating condition.
Cause: The TP function is on and the station inadvertently broadcasts the traffic information identifier (TA). This interrupts the cassette / CD operation.
Radios concerned: All
Note: The old status can be restored by switching off the traffic information function (press TP).
Volume / speakers
Speed-dependent volume increase is too weak / too strong
Cause: Set speed dependent volume characteristic curve is not adapted to the vehicle.
Radios concerned: All radios except of the Top HiFi System is fitted.
Note: Change the speed dependent volume (GAL) control setting in the DIS under service functions. GAL1 corresponds to the smallest volume increase, GAL4 or GAL6 are the greatest rises.
Speed-dependent volume is not increased
Cause: Top HiFi System fitted
Radios concerned: All E38 and E39 radios with Top HiFi System.
Note: In conjunction with the Top HiFi System, only one characteristic curve is permanently stored in the Top HiFi amplifier. The different GAL stages in the radio are not in operation.
Volume between two stations or between radio station and cassette or CD differs greatly on switching over.
Cause: Radio stations can broadcast at different modulation levels. The cassette or CD might have been recorded at a different volume.
Radios concerned: All
Note: Check playback using other stations, other cassettes or CDs.
Loudspeakers boom, rattle or do not produce the desired sound pattern
Cause: Loose speaker cables can strike body components or neighboring body components can also vibrate.
Radios concerned: All
Note: Check cables over the entire length and fix with insulating tape as required. Attention should also be paid to ensuring that no neighboring body components are able to vibrate.
Temporary failure of opposing speaker
Cause: Abrupt changeovers from stereo to mono give the impression that a loudspeaker fails.
Radios concerned: All
Note: In the event of audible interference in reception, reproduction is switched over from stereo to mono as such interference is perceived to be unpleasant in stereo.
Station storage
It is necessary to reprogram the stations when driving through different broadcasting areas.
Cause: The station with the strongest signal in the relevant area can be selected with the auto-store function.
Radios concerned: Business and Reverse
Note: Activate auto-store function by pressing and holding the FM button. Selection of station buttons in FMA mode.
