With all the Bimmers I've had over the years, not once was I ever given a copy of the actual Service Bulletin...just the SIB# on the invoice.

Sorry!

Can anyone else access the details of this SIB?

TIA

SUBJECT
Clock Resets and/or Battery Discharged

MODEL
E70 (X5)

SITUATION
The customer states that the clock resets. In extreme cases the battery may become discharged.
INSTR (Instrument Cluster) fault "A559 Supply was switched off (terminal 30g_f)" may be stored.
CAUSE
The terminal 30g_f fault stored in the Instrument Cluster does not indicate a defect in the cluster, rather a disconnection of the power supply of the instrument cluster by the JBE (Junction Box Electronics), to protect the battery from becoming fully discharged. This disconnection can be caused by any one of the following:

• Frequent wakeups
• Closed circuit current faults
• Sleeping inhibited
• Driving profile
• Starting capability limit reached

PROCEDURE
Follow the DIS test plan for the instrument cluster fault. The test plan will be amended to bring up the Energy Diagnosis test plan. The Energy Diagnosis test plan can also be called up manually by selecting "Function selection/Complete vehicle/Body/Power supply/Energy diagnosis/Execute energy diagnosis".
Once you get to the results screen "The energy diagnosis procedure analyzed following information from the vehicle:" select [1] Notable information (number 1). The number that is indicated in parenthesis is the number of most likely causes. Always select button [1] first and continue troubleshooting as per the test plan.
Refer to SI B61 08 00 for more information on closed circuit current diagnosis.
WARRANTY INFORMATION
Covered under the terms of the BMW New Vehicle Limited Warranty.

SUBJECT
Closed-Circuit Current Measurement

MODEL
All

SITUATION
Increased closed-circuit currents may occur permanently or intermittently and cause the battery to discharge prematurely. The increase in closed-circuit current may be caused by a faulty control unit, or by the installation of a non-approved accessory.
In a situation where a vehicle has broken down due to a discharged battery, for diagnostic purposes it is important not to disconnect the battery. This is because a control unit will be reset if the battery is disconnected. Following a reset, the faulty control unit may start functioning correctly again, making accurate diagnosis impossible.
To correctly measure closed-circuit current, the 50-amp clip-on probe can be used in conjunction with the DISPlus to properly diagnosis closed-circuit current problems over an extended period of time. Refer to Service Information B04 07 01 for information about the 50-amp clip-on probe used with the DISPlus. A new 50-amp clip-on probe (refer to SI B04 16 04) can be used with the GT1 in conjunction with the MIB (Measurement Interface Box). Refer to SI B08 02 04 for information about the MIB.
PROCEDURE

1. It is very important that any "Power management" faults stored are diagnosed and corrected and that the "Energy Diagnosis" test plan be carried out before the following procedure is performed.
2. Check and test the battery using the BMW Battery Tester. Refer to SI B 04 25 02 for information about the BMW Battery. If necessary, recharge or replace the battery.
3. If the battery is installed in the trunk, open the trunk and turn the lock to the locked position using a screwdriver or similar (simulates the trunk lid being closed). The hood must be closed.If the battery is installed in the engine compartment, open the hood and pull the front lid contact switch fully up and lock in this position (workshop position, simulates the front lid being closed). The trunk must be closed.
4. With the exception of the trunk/hood above, all other doors/lids must be closed.
5. In order to simulate normal closed-circuit conditions:
   • Turn the ignition on and activate all electrical consumers, including any accessories. Turn the ignition off. In some cases, a drive cycle may need to be carried out in order to duplicate a closed-circuit current problem.
   • Open and close the driver's door (simulates somebody getting out).
   • Lock the car, arming the DWA if this is installed.
6. In general, closed-circuit current consistently over 50 mA must be investigated. Depending on the vehicle's equipment, closed-circuit current by vehicle model is approximately as follows:

E31
50 milliamps after 16 minutes
E32
50 milliamps after 16 minutes
E34
40 milliamps after 16 minutes
E36, Z3
30 milliamps after 16 minutes
E38
50 milliamps after 16 minutes
E39
40 milliamps after 16 minutes
E46
40 milliamps after 16 minutes
E60, E61, E63, E64
40 milliamps after 60-70 minutes
E65, E66
40 milliamps after 60-70 minutes
E53
40 milliamps after 16 minutes
E70
40 milliamps after 60-70 minutes with TCU (30 minutes without TCU)
E83
40 milliamps after 16 minutes
E90, E91, E92, E93
40 milliamps after 60-70 minutes with TCU (30 minutes without TCU)
E85
40 milliamps after 16 minutes
E52
50 milliamps after 16 minutes

1. If the nominal milliamp reading is not achieved after the appropriate time, refer to the attached troubleshooting charts:
   • E60, E63, E64 Closed-Circuit Current Troubleshooting E6x up to 9/05 production
   • E60, E61 Closed-Circuit Current Troubleshooting from 9/05 production
   • E65, E66 Closed-Circuit Current Troubleshooting up to 3/04 production
   • E65, E66 Closed-Circuit Current Troubleshooting from 3/04 production
   • E90, E91, E92 Energy Diagnosis Hints
   • E70 Energy Diagnosis Hints.

CLOSED-CIRCUIT CURRENT MEASUREMENT WITH THE DISPLUS/GT1:
Note: This technique with a DISPlus/GT1 is particularly suitable for extended measurements and provides a graphical readout of recorded measurements over time. It is recommended for situations where the use of a multimeter provides insufficient information for problem diagnosis.
Select "Oscilloscope display" on the Oscilloscope settings screen to start recording measurements. Select the Log Scale/Lin Scale button to switch over to the Log Scale. This will provide the best visual trace of the closed-circuit measurement. Note: Pressing the "Oscilloscope settings" button will delete any recorded measurements.
Oscilloscope Setting

• Select "Writer mode".
• Select "Current 50A" under "Test connection".
• Select "=" under "Type of measurement".
• Set "Measuring range" to "10 A" scale.
• Set "Frequency range" based on how long a trace is required. Refer to the chart below for examples.

Frequency range - The frequency range determines how frequently and for how long a measured value is recorded. The larger the frequency range, the more frequently a measured value is recorded, and the shorter the maximum stored recording duration.
Examples:
Set "Frequency range"
Number of Measurements
Maximum duration of recording
2 mHz
1 per second
83 minutes
1 mHz
1 every 2 seconds
2.7 hours
0.4 mHz
1 every 5 seconds
5.5 hours
0.2 mHz
1 every 20 seconds
27.7 hours
Oscilloscope Display

• Select "Oscilloscope Display".
• A box will pop up calibrating the 50-Amp clamp. Make sure the clamp is not connected to anything and then select "OK".
• Once the display screen is present, the measurement will be started. Select Log Scale/Lin Scale to switch over to Log Scale. The Log Scale screen will then be displayed in 3 different measurement ranges. This ensures that when the closed circuit current measurement drops through the various ranges, the reading will be graphically displayed on one screen without changing settings.

Displaying and Understanding Measurements (see illustration below):

• Stop recording measurements by pressing the "Hold Screen" button. Note: If the "Hold Screen" button is pressed again, the recorded measurements will immediately be deleted and new measurements started.
• Recorded data may be called up by pressing the screen button "Memory" and paging through with the aid of the "arrow keys" on the upper corners of the screen. When the maximum recording duration has been used, measured values can be called up for a total of 10 screens.
• Momentary current fluctuations are normal and should be ignored. The "Maximum" display captures these momentary fluctuations and also should be ignored.
• An increased closed-circuit current will also be intermittently measured for a few seconds due to the use of remote-control keys of other vehicles, or other radio transmitters in the frequency range 315 MHz. In these cases, the General Module wakes up for key identification, then goes back to sleep when its own key is not recognized. This is normal operation.
• On vehicles equipped with BMW ASSIST, there are additional current fluctuations as high as 500ma that last for approximately 2 minutes. The fluctuations occur every 15 minutes for up to 14 hours after key off. This is considered the normal operation of the TCU and should not be considered a fault. This also applies to 2005 TCUs that are installed into earlier production vehicles as replacement parts.
• On E65 and E66 vehicles equipped with Comfort Access, the Troubleshooting attachment for vehicles from 3/2004 has been updated to include additional information on how to troubleshoot the Comfort Access system. Thanks to Sergio Escudero from Braman Motorcars for this information.
