Technical Service



This Service Information bulletin supersedes SI B61 08 00 dated December 2010.



[NEW] designates changes to this revision



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.



[NEW] To correctly measure closed-circuit current, the 50-amp clip-on probe (previously used with the MIB) or the 100-amp clip-on probe can now



be used in conjunction with the IMIB (Integrated Measurement Interface Box) to properly diagnosis closed-circuit current problems over an



extended period of time. Connect the amp clip-on probe directly to the IMIB Measurement input 3 (green socket). Refer to SI B04 35 09 for



2010 BMW 335Cic Convertible (E93) L6-3.0L Turbo (N54) 50



information about the IMIB.



WARRANTY INFORMATION



Not applicable



Procedure



PROCEDURE



1. [NEW] It is very important that any "Power management" faults stored be diagnosed and corrected, and the "Energy Diagnosis" test plan



carried out before the following procedure is performed. Only perform this procedure if closed-circuit current violations are listed in the "Most



Likely Cause" list.



2. [NEW] Check and test the battery using the BMW Battery Tester. Refer to SI B 04 25 02 for information about the BMW Battery. Refer to SI



B61 02 11 for vehicles equipped with advanced onboard battery diagnostics that do not require the BMW Battery Tester. 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.



2010 BMW 335Cic Convertible (E93) L6-3.0L Turbo (N54) 51



6. In general, closed-circuit current consistently over 50mA must be investigated. Depending on the vehicle's equipment, closed-circuit current



by vehicle model is approximately as shown above.



7. If the nominal milliamp reading is not achieved after the appropriate time, refer to the attached troubleshooting charts. On 2005 MY 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 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.



^ E60, E63, E64 Closed-Circuit Current Troubleshooting E6x up to 9/05 production



^ E60, E61, E63, E64 Closed-Circuit Troubleshooting E6x 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



^ Normal closed-circuit current values for E65, E70, E60, E61, E63, and E64



CLOSED-CIRCUIT CURRENT MEASUREMENT WITH THE IMIB



Note:



This technique with an IMIB 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 provided insufficient information for problem



diagnosis.



1. The IMIB can be accessed from any ISID within the workshop.



2. Select "Activities".



3. Select "Measuring devices".



4. Select from the "Level 1" column, "Measuring devices", and then "OK".



5. From the "Connection manager" screen, select the free IMIB and "Set up connection".



6. The "Measures devices" screen opens on the "Multimeter" tab.



7. Select the "Oscilloscope" tab.



8. Highlight the "CH1" tab to activate channel 1.



9. Under channel 1, "Source", scroll with the arrows to select "Clip-on probe 50A".



10. Make sure that clip-on probe is not connected to the battery cable, and acknowledge the pop-up message with "OK".



11. Change the "A/Div" setting to "1A".



12. Under the "Time" selection box, change the "Time/Div" setting based on the number of measurements needed (5 ms to 200 s). The longer



times should be selected when performing the measurement over an extended period.



13. Select "CH 1" under "Cursor" to monitor the actual readings.



14. Select "Record" if performing long term measurements.



15. After performing the measurement, select "Record" again; the display will change to "Compress" and display the recorded data on the 1



screen.

He said/She said: 2016 Mazda CX-3 CUV Review

By: Dan Heyman & Lacey Elliot When I was asked to take the 2016 Mazda CX-3 for a spin, I found myself surprisingly excited considering that this type of a car—small/compact crossover—isn’t usually my cup of tea; as a certified auto journalist, and thus, somewhat unbalanced, I’m a big station wagon and hatchback kind of guy. I’ve always felt they provided all the creature comforts of an SUV or CUV, while still providing an engaging ride. However, the CX-3 is a Mazda, and Mazda has to be respected for always finding a way to add that certain je ne sais quoi that makes a car fun to drive and behold, whether that has to do with some funky styling, a firm chassis or engaging powertrain. That’s what happens when you’re known for continually building one of the world’s most exciting, fun-to-drive and above all, affordable, sports cars on the market: the MX-5. Styling So, with that in mind, I sauntered up to our CX-3 tester, finished in brilliant Soul Red metallic paint, and took it in. T...

Product Review: MyZone® Heart Rate Monitor

Today I’m writing up my review of the MyZone® HR monitor! I’ve been using mine now since May and have tested over a range of activities, so now I really believe I can give y'all a fair and informative review. Now, let’s start with the basics. I have the MyZone® MZ-3 physical activity belt, which retails for £129.99 – which, for a heart rate monitor, is fairly pricey considering you can get something like a Wahoo TICKR belt for ~£65 . Purchasing through a MyZone® representative is generally the best way: these tend to be personal trainers or gyms affiliated with the brand. For example, where I live you can get a belt through Henley Fitness Space and save something like ~10% off the RRP. Comfort wise it took a bit of adjusting for me to get used to the belt, but once I found the right position (which for me was just underneath my sports bra) I actually barely noticed the belt was there – which surprised me considering how bulky the monitor is. I find that in this position it sits jus...

Mercedes-Benz ML63 AMG Reliability - 2018 Ratings

New AMG SUV is the first full-size SUV which has that two way of building combined. 2 separate 1/4 mile records were made by two separate RENNtech cars at Palm Beach International Raceway on Wednesday night. The C350 took everything up a notch, but again not a night and day experience, while the C63 is otherworldly, its power devastating, adhesion and correlating road manners unfathomable for such a solid, substantial four-door sedan. I took my girlfriend to an Italian restaurant in Austin, Texas that we had both wanted to try for a while. While the show car does not look anything like the current Impreza, equally Subaru insists the concept鈥檚 styling forms only a guide to the production WRX. The interior of this car has been designed to have an elegant yet sporty look that matches perfectly with the vehicle鈥檚 overall appeal. To get the power onto the road, the rear tires are wider than the front ones on a mid-engined car - usually about 30% wider. Also look for a return of the hybrid S...

Product Review: Garmin Vivoactive 3

So. It’s now been a few months since I’ve had the Garmin Vivoactive 3 and I now think I’ve taken it for enough of a spin to make my full and honest opinion. In short, I very much enjoy the watch and it’s a great training tool but still certainly has its downfalls. The Garmin Vivoactive 3 is a multisport watch with built in wrist HRM, and as with all wrist based HRM that’s were it tends to fall flat. I use my watch primarily to track my rowing, however I’ve also tested it on runs, cycles, swims, ergs, indoor cycles and weights so I’ve tried it all (except golf…). I think the best way to break down my review is to split it into the sports, so I’ll start with the main one for me: rowing. Rowing On the erg I split between either using the ErgIQ app which I downloaded, or just the ‘indoor rowing’ application already on the watch. Out of these I find the ErgIQ gives me the best data, though the concept2 PM5 set up at Leander seems to be slightly temperamental with whether they’ll pick the wa...

We Rank The 5 Audi RS Cars Sold In The US From Worst To Best

Amazingly, only six RS cars have even been sold in the US. RS is to Audi as AMG is to Mercedes and M is to BMW. Even though BMW and Mercedes are quickly expanding their performance portfolios in the US, Audi has lagged behind in offering RS cars in North America. In fact, there was a time when Audi only sold one RS model at a time. This means that (excluding generational overlap) there have only been six different RS models on sale in the US. With only six cars to choose from, we decided to rank the five best RS cars that have ever been sold in the US from so-called "worst" to best. Coming it at number five (the lowest spot) is the RS5. We decided to put the B8 and B9 generation RS5 on this list because neither is our favorite RS car. The RS5 had a few issues. For instance, the engine was out passed the front axel line, which caused understeer. The first RS5 had a naturally aspirated 4.2-liter V8 , which sounded great, but the new car uses a 2.9-liter twin-turbo V6 which a...

2018 Mercedes-Benz AMG C 63 Expert Reviews, Specs And Photos

Under its rear hatch lies a two-cylinder diesel that generates 47 hp, which would have been fairly weak in 1960, much less in the era where the average Hyundai generates up to 200 hp. The new rear fenders make the AMG GT C a total of 2.25 inches wider than the AMG GT and AMG GT S, giving it exactly the same dimension as the AMG GT R at the rear of the car. These are the same rubbers that Nissan used during their 鈥榠nfamous鈥?fast lap of 7mins 29secs at Nurburgring, a timing which was controversially disputed by Porsche recently. 2017 Porsche 991.2 Carrera GTS Photos Redesign for USA, Canada, UK.
