Voltage & Module Programming?
I recently bought a snap-on EEBC500A smart battery charger just for programming. But I cannot find anywhere online that can tell me what the charging voltage specs are for each manufacturer. Could not even find it on prodemand . Doe's any know anything or anywhere that can point me in the right direction? I would greatly appreciate it, thank you.
I don’t know if there are certain specs really. The most important thing is the battery voltage doesn’t go to low. I use a Snap-On charger and set the voltage at 14 volts. The important thing is to have a good constant voltage. Hope that helps.
I don’t know if you will find what you’re looking for. As a “rule of thumb” Asian and Domestic, I use 13.2-13.5 volts. European I use 14.2-14.5 volts. That should keep you out of trouble. Some Euro platforms require 90 amps, not sure the Snap on will do that, unless they upgraded it. Mine is 60 amp I think.
Thank you Jamey. I'll will remember that rule of thumb.
Ford recently published a General Service Bulletin on programming and it shows 12.6 to 13.6 GSB 20-7023 Its got some great information on which process to choose as well.
Thank you again for your help Chris. I will see if i can read that GSB bulletin.
After I determine battery is fully charged I set voltage to 13 volts. Except bmw I use midtronics instead of snap on. Many years ago I was flashing chrysler and was stopped by screen stating voltage to high. But then times,procedures and such has changed and probably only one to answer on new cars is mobile techs or individual dealer mechanics. I have set up computers up to 2017 so at a loss on…
Thank you Ronald. I'll take that into consideration when dealing with BMW's.
I'm assuming your Snap On charger is not an EEBC500 as that has the "flash programming" setting built in. In my experience, a battery charger is better than nothing when performing module programming but what you really want is a conditioned power supply to maintain the system power. We use a Midtronics PSC-550 for all of our programming and testing. Output specs on the unit are 13.4 Vdc/Vcc and…
BMW as as a rule of thumb cannot go over 15v cannot go under IIRC 13.8v
Thanks Paul, and yes it is EEBC500A. I will have to continue reading that article. Thanks for the link.
I don’t go by specs. 13.5 domestic and Asian and 14.4 euro. Always worked for me
Great question! I have always wondered that exact thing.
