Is jump starting bad for the other car's computer?

Old wive's mechanics tale?

A month ago my car wouldn't start in the morning. Jumped it and off I went and no more problems.

Today same thing happened.

Intermittent dead battery. Jump started and off I went. No trouble rest of day.

Neighbor said that jump starting from a newer car is bad for the car's computer (and I guess electrical system).

Is this BS? If done right is there a danger to the charger car?


Will take the battery out tomorrow and check age and charge, etc.

Car had it's 30k service check 4 months ago.

I can't figure out why I am having this intermittent problem.

*Remove the battery and throw it on a trickle charge and test it.
*This way by having the battery out you are bleeding off the voltage from the vehicle.There are a lot of small transistors that retains/keeps power up to 30 minutes of battery disconnection(DME main relay).
*If your battery is 4 years old,I recommend replacing it.More so now that winter is coming and I have seen a few frozen batteries living/making a living in NY.
*It may also be possible that you have a parasitic draw.But since this is the first (if you are going to replace the battery) battery replacement you are going through I would say very unlikely.


*Disconnect battery and bleed off remaining power.There is a possibility that you may have a malfunctioning/sticking relay or transistor that wakes up the control unit associated with it.
Thats like looking for a needle in a haystack so by removing power to it completely gives it a fresh and renewed state of operation the next time it "boots up".

I can't figure out why I am having this intermittent problem.

All the methods were covered in the previous post as to how to handle the battery.

What I will add is an answer to your question. Yes it can damage the other cars ecu.

It can also damage your ecu and other components. When you jump a car off there are tons of things that can happen. First your alternator is in overdrive so to speak handling the load of what your car needs plus the extra resistance of the other cars battery plus its current needs to crank.

If the cables get crossed up you can short out your own cars system plus it can fry the other cars stuff. Then theres the moment you disconnect the battery cables. You voltage levels jump up sky high for that instance as you have lowered the resistance on the other end.

Best way to jump start another vehicle if you have to do it is hook up both ends of the cables before ever cranking either car. Then crank the car that has the good battery first. Wait a few minutes for the other cars battery to build up some. Then try to crank the one having problems. The turn OFF the car with the good battery. THEN disconnect the cables.

How else do I charge it if not with another battery?

We did everything except turn off the charger car before removing the batteries. If done the "best way" can there still be harm done?
Thanks for the advice.

intermittent stuff drives me nuts.

If you own a car or a lawnmower then you should own a battery charger. Thats how to charge it.

Go to walmart or an autoparts place and buy a $39.95 battery charger. Thats how to charge the battery. If you buy a good one it should say something like "New electronic pulse technology reverses the natural insulating sulfate buildup on plates".

This will actually extend the life of your battery while recharging it.

You did not mention the age of your car, but at 30K miles, a new battery would be a good idea, as mentioned by a previous poster. The battery is the easiest part to replace, and not all that expensive. If replacing the battery eliminates the problem, well, you're good to go.

If not, at least the battery was getting old, and you will have peace of mind through the winter.

In the meantime, you are dicking around jump starting the car, running a risk of possibly damaging the ECU or the alternator. Not worth it.

Mein Auto: A few choices
The ideal way to jump start a car is with the other car OFF. There is no risk of damaging anything on the other car if its off. (Unless you connect cables wrong, like Crowz said, but if you can't handle that, you shouldn't be attempting a jump start)

Jump starting a car this way, you are basically using the other battery in place of yours.

Once you start the other car, you are using their battery AND alternator. The risk to the ECU in the other car (again, assuming you don't connect cables wrong) is VERY close to zero. It would be very difficult to damage it, but anything is possible. The bigger risk is to the alternator. Starting a car requires a LOT of current, and the alternator is not always capable of supplying that much.

In a nutshell, jump your car with another car that has a big battery while that car is completely off, and you will have to really screw it up to damage anything.

Doesn't the charging system do the same thing (other than that "pulse technology stuff")?

I can go get one but when you need to go to work - you need to go to work. A battery charger takes quite a bit of time to charge up a car, doesn't it?

The battery was replaced when I bought the car 16 months ago.

By the way, it started right up this morning. and I pretty much think I won't have any problems again for a while if this issue follows the pattern...

I'll definitely start with looking to see if the battery is defective but this intermittent stuff is killing me.

A modern charger takes about 15 minutes to get a battery crankable, if it takes longer than 15 min its time for a new battery

Also there is a TSB I posted on here about some cars not going into sleep mode and killing the battery.

Wow!

I did not know that.

SOLD.

Do you have the link to the TSB or to BMW TSB articles in general?

I bet it is a computer glitch - if it is not an looming battery failure.

I just finished look thru my stuff and cant find the exact tsb nor can I find where I posted it on here before which I know I did. There are actually several that fit this across different years and with different equipment.

The only one I found is this one which isnt the one I had in mind :

Accessories and Optional Equipment: All Technical Service Bulletins
Campaign - Telematics Control Unit Inspect/Replace
B84 01 04
February 2004
Phone, Navigation Systems
Service Engineering
This Service Information bulletin supersedes S.I. B84 01 04 dated February 2004.
PERFORM THE PROCEDURE OUTLINED IN THIS SERVICE INFORMATION ON ALL AFFECTED VEHICLES THE NEXT TIME THEY ARE
IN THE SHOP FOR MAINTENANCE OR REPAIRS AND PRIOR TO RETAIL DELIVERY.
[NEW] designates changes to this revision
SUBJECT
Service Action: Check and Replace TCU
MODEL
E46 (3 Series), E85 (Z4), E53 (X5), E83 (X3).
SITUATION
Low ambient temperatures (below 32F) may cause the TCU (Telematics Control Unit) to go into reset mode. The result is that calls to BMW Assist or
"SOS" calls will not be completed.
Once in reset mode, the TCU will remain in this condition even with the ignition turned off. This could result in a discharged battery.
This Service Action will check the TCU and replace it if necessary. Copies of the customer notification letter and Q&A are included.
To minimize customer's inconvenience caused by this service action, pick-up (and deliver after repair) the affected vehicle from customer's home or
provide appropriate alternative transportation.
Customers will be impressed when you return their cars cleaned inside and out and with a full tank of gas. Reimbursement information for the vehicle
fueling and valet costs may be found in the Warranty portion of this bulletin.
AFFECTED VEHICLES
This Service Action involves E46 (3 Series), E85 (Z4), E53 (X5) and E83 (X3) vehicles which were produced from 8/2003 to 11/2003.
In order to determine if a specific vehicle is affected by this Service Action, it will be necessary to utilize the "Service Menu" of the DCS (Dealer
Communication System). Based on the response of the system, either proceed with the corrective action or take no further action.
The Chassis Number Ranges listed below are only for informational purposes and are not to be considered as the only deciding factor.

CAUSE
Telematics Control Unit (TCU).
PROCEDURE
1. Read the ESN number from the label in the Owners Manual insert. The ESN is shown immediately above the bar code.
Note:
If the Owner's Manual insert cannot be located, connect the DISPlus/GT1 and perform a "Short test". Select "Control Unit Functions" / "TCU
Telematic Control Unit" / "only US" / "Read ESN number", and press "Display" to read the ESN number.
2. Using the TIS website, in the "Bulletins and Measures" section, press the special button marked "TCU lookup".
Follow the on-screen prompts to enter the vehicle VIN and ESN, then press "Enter" to display whether the TCU must be replaced, or not be
replaced. Press the "Print" button and attach the printout to the repair order.
3. For vehicles where the TCU does not have to be replaced, no further work is necessary.
For vehicles where the TCU must be replaced, switch off the ignition and remove the TCU, which is located behind the trim in the left luggage
compartment (on convertibles the TCU location is on the left rear bulkhead, accessed via the trunk).
4. Before installing the replacement TCU, make a note of the Electronic Serial Number (ESN) and copy this information onto the "TCU Registration
Form" attached to this Service Information, and fax the form to the number indicated on the form. This will register the new TCU to this vehicle.
5. Remove the ESN label from the replacement TCU, and affix the new label over the existing label on the Owner's Manual insert (P/N 01 49 0 157
963).
6. Install the new TCU and code it with DIS CD36.1 or higher (E46, E53) or CIP 10.1 or higher (E83, E85).
7. NOTE: In order that the TCU replacement is properly recorded, FASTA must be activated in the DISPlus/GT1. For details on activating FASTA,
refer to SI B07 07 01.
Using DISPlus/GT1, select "Diagnosis" and delete any stored fault codes.
8. Test the BMW Assist service for proper operation by placing a test call.
Note:
The MFL button on the steering wheel must not be used.

First thing first. Once the car starts the battery is no longer in use (the battery only gets charged if needed and a relay takes care of that).

If you connect the cables properly there is no demage to ECU done at all as long as you hook plus to plus and minus to minus. Once this is done voltage evens out but never goes beyond 14-16 Volts (as the alternator produces this much) unless you are jumpstarting a car from a tracktor trailer with a 24 Volts battery then your ECU will indeed get fried.

When you do a paralel connection (as the jump start is done), the voltage stays about the same but it never passes the source voltage. The only change that happens is you get more Amperes (Working Power).

The only demage that is possible is actualy the person who is helping you jumpstart your car. His/Her alternator will have to work very hard to provide the juice needed for your Starter.

Umm wrong. A battery is in series with the charging system at all times. It is never "disconnected" from the charging circuit. The system charges at all times trying to keep the voltage at a set point. If that point is 14 volts which is normal on most new vehicles then it will try to maintain 14 volts. Notice thats 14 volts not 12 volts. Your battery is 12 volts. By applying 14 volts to it the 12 volt battery is "charged". If the system maintained under 12 volts aka lets say 9 volts and stopped charging when the voltage was higher than 9 volts then the battery would eventually run down as it would be putting out 12 volts and the accessories and such would be running off the battery all the time.
So no there isn't a relay that turns the battery off when you crank your car.

if you had to jump the car twice already, your battery is most likely on its last leg. working at a tire store as a kid, we always had people with battery problems at the hottest and coldest time of the year. this is when your battery starts to feel the stress of life, so to speak.

when a battery goes it is similar to an alternator failure... you may be able to trickle charge it time and time, but at the end of the day it will ultimately fail, and problems with your battery are suggestions that it is time.

i agree that you should have a battery charger in your garage for emergency use, and especially if you have a car that sits for a period of time.

Crows, have you ever disconnected the battery while the engine is running? If you did that you will notice that the car runs without a problem.

Second, if the battery and the alternator was in series, you will get 12V+14V = 26V. Caboom all circuits are fried Looks like you need to review your physics, the chapter about Electrical current.

But my bad, I should haave said a regulator not a relay (this was old school).

Yeah Ive done the pulling the battery loose while the motors running on OLD cars. I dont recommend it anymore as it frys todays setups.
Plus I meant connected not in series. The battery is ALWAYS connected no matter what the alternator is putting out or doing. The Alt just puts out extra juice as needed. It doesnt control the battery what so ever.

You can always try for the ol' push start. It does work and no, it won't damage the car if done right. I've done it with both an E39 and my own E46. No adverse effects in either case.
But, as noted above, your battery is probably due for replacement.
