Now the alarm is going off on it's own. BMW-planet schematics will not open. I emailed them and in the course of helping me figure out why I could not see them they found a problem with internet explorer 8. They are working on a fix.

 

Ski...you're having a tough time catching a break on this. Glad BMW-planet is on it too. This document states alarm activation due to rapid battery discharge among other things. Doesn't solve your problem
but at least explains your alarm.

Antitheft Alarm System
Functional description, see BMW Technology:

TIS -> Documents> SI Technology -> 61 09 03 (031)

Notes on function
The DWA electronics are integrated on the ultrasonic signal/interior sensor control unit. They evaluate the signals relevant to the alarm system and decide whether the alarm should be triggered. The control unit is connected to the data bus K-CAN SYSTEM, across which it receives the signals of the door modules and CAS and body base module control units. In addition, a separate DWA data bus is connected to the control unit, across which the signals between the DWA electronics and the control unit emergency siren/inclination sensor (SINE) are transferred.

The inclination sensor and the emergency siren are grouped as one component. They are linked to the DWA electronics across the DWA data bus.

The inclination sensor monitors the horizontal and vertical position of the vehicle and issues an alarm signal in the case of a position change.

The emergency siren emits an acoustic alarm if required. The alarm is triggered when the siren receives a corresponding command from the DWA electronics.

In addition, an alarm is triggered independently of the DWA electronics under the following conditions:

Emergency siren is disconnected from the vehicle electrical system

Disconnection of the vehicle battery

Rapid discharge of the vehicle battery

Overvoltage in the vehicle electrical system (voltage > 16 V)

So that the emergency siren can operate independently of the vehicle battery, it is given a rechargeable battery that is charged when the engine is running.

 

Thanks. At least I know the alarm is not another symptom. I have no idea what to do next other then disconecting computers. Anything to watch out for if I do that?

 

I hope this isn't too much information. Check out Terminal 30g-f about 3/4 of the way down. It talks about the KGM shutting down the TCU, MASK, and CCC. Maybe related to
your bluetooth, audio, and iDrive malfunctions.

Energy diagnosis: Terminal control
The terminal control is distributed across various control units. The following block diagram provides an overview of the control units involved and the integration in the vehicle electrical system.

Terminal 30g-f: Terminal 30g-f is a terminal 30 that is only switched off if faults are detected.

As of model year 09/2005, the micro power module will be eliminated as an independent control unit. The KGM controls terminal 30g-f across a bistable relay that is firmly soldered on the board of the control unit. The bistable relay can be switched off or on. As a rule, the bistable relay is always switched on. The bistable relay has two relay coils and it always remains in the last state activated (switched on or switched off).

In the event of faults, before the KGM finally switches of terminal 30g-f, a reset is run for 10 seconds. This removes any failures of the defective control unit. If the fault is persists 5 minutes after the reset, terminal 30g-f is switched off.

There are the following three fault cases:

The DME/DDE permanently monitors the state of charge of the battery using the IBS. When the starting capability limit is reached, the IBS wakes the vehicle and the DME/DDE sends a message to reset terminal 30g-f. The KGM receives the message and switches the bistable relay off for 10 seconds.
If the state of charge continues to deteriorate after the reset, the DME/DDE sends a message to cut off terminal 30g-f. The KGM receives the message and switches the bistable relay off after an after-run time of 2 minutes.

As of terminal R off, the KGM monitors whether the vehicle is able to go into the idle state. The vehicle can only enter the idle state when all the control units are ready for this. If not all control units have signalled readiness after approx. 60 minutes, the KGM switches terminal 30g-f off for 10 seconds.
If not all control units have signalled readiness 5 minutes after this reset, the KGM switches terminal 30g-f off after an after-run time of 2 minutes.

A few minutes after terminal R off, the vehicle has normally switched into the idle state. As of the idle state, the KGE counts how often the vehicle is wakened. The KGM switches terminal 30g-f off for 10 seconds when a vehicle has been wakened unexpectedly more than 30 time with terminal R off.
If the vehicle is wakened 5 more times unexpectedly after this reset, the KGM switches terminal 30g-f off after an after-run time of 2 minutes.

In all cases of the reset and cutoff, a fault is entered in the KGM. The reset or cutoff of terminal 30g-f is independent of what triggered the detected fault. The reset and cutoff are only an attempt to remedy the fault in the vehicle and prevent it from not starting. The reset cutoff of terminal 30g-f does not necessarily mean that there was a fault in a consumer unit of terminal 30g-f.

The switch-on condition for terminal 30g-f is switching on terminal R. For this reason, with terminal R or terminal 15, terminal 30g-f is always switched on.

Control units supplied by terminal 30g-f:

CA- Comfort Access

CDC- CD changer

Instrument cluster

M-ASK- Multi Audio System Controller

CCC- Car Communication Computer

CNAV- Navigation system China

JNAV- Japan navigation system

KBM- Body base module (as of model year 03/2007)

TCU- Telematic Control Unit
(as of model year 09/2006, only US version)

ULF- Universal charging and hands-free unit


Terminal 15: Control of terminal 15 is by the CAS depending on operation of the start/stop button (with the key inserted in the key slot).
The gearshift mechanism of terminal 15 is switched in the CAS via semiconductor switch. A relay in the distribution box is activated via the output of a semiconductor switch. The relay switches the voltage of the battery to approx. 4 fuses in the rear distribution box. The consumer units of terminal 15 are essentially supplied from here.

Control unit supplied by terminal 15:

FLA- High beam headlight assistant


For safety reasons, some control units have a terminal 15 line directly from CAS, e.g. the LM (light module) or the CVM (convertible top module).

Terminal 87: The DME/DDE controls terminal 87 via a relay in the E-box or integrated supply module, as the case may be. Terminal 87 is switched on as soon as terminal 15 is switched on. After terminal 15 has been switched off, terminal 87 is switched off by the DME/DDE with a slight delay.

Control unit supplied by terminal 87:

VTC- Valvetronic


Terminal R: Terminal R is not present as a hardware terminal. One control unit is directly supplied by the CAS via terminal R:

ACSM- Crash Safety Module

 

Great info. Am I reading this correctly? Due to the battery being discharged to fast or the car waking up to often the radio, bluetooth etc. are shut off? If so all is still related to the battery draining. Any ideas on fixing the root cause of these problem?

 

Thanks 503inOK

That has to be the best page of info I have read on the E60... ever.

 

From what I understand battery voltage is monitored and functions disconnected/disabled to preserve enough battery capacity to start the car. Without getting the fault codes read it may be difficult
to determine the module/modules causing the problem. Pulling fuses to power down a module also removes it from communicating on the bus. I'm not sure if the KGM would interpret that as a faulty
module and proceed with shutdown. As a process of elimination it's worth a try. The only ones to watch out for are airbags and seatbelt tensioners disconnected from the crash safety module then reconnecting the battery. The fault code requires a dealer reset.
Too bad we can't monitor bus activity and determine what the modules are saying. A trip to the dealer to check fault codes may be in your future.
I hope you can get it sorted out on your own. Let me know if you need module/fuse locations.

 

Haha I don't make the news...I just report it

 

I've got permission from the boss (wife, it's her car) to order Auto Enginuity or Bavarian Technic scan tools. Both of these tools are supposed to be able to everything we need a scan tool to do. I have Auto Enginuity for my truck it works great. It does every test and scan on my truck as the dealer can.

If I need it I'll get it. I be getting one of these tools eventually. I have the fuse locations unless there are more then what is listed on the sheet in the tool compartment. The fuses I know of are right above the battery and in the glove box. I don't know where the modules are.

 

Concur! This is "keeper" information. Thanks 530inOK.
I also had problems with BMW-Planet schematics, glad to see they are correcting this.
