Question OBC Issues

Hey Everyone,

My first thread so here it goes:
Had my alternator replaced a few months ago by an indy shop, and started having problems with the OBC. Would only show outside temp (and was accurate), but I couldn't scroll through anything else or change the time.
Just had my GM5 repaired, so had to disconnect the battery again, and after hooking everything back up, my OBC reads only dashes (--:--) and I can't get it to do anything else.
I've found the OBC test pages in my Bently manual, but was hoping for a little input before I start messing around with things.
Anyone ever seen this or know what's going on???

Thanks so much!!

based on the dashes you have drawn, have you set the clock?

OK, I was able to get the clock to reset so now it shows the time, but it still won't toggle through any of the other functions, i.e. mpg, average speed, miles to go, outside temp, etc..

Any insight???

Hmmmm, sounds to me as if the car has forgot that it's coded for obc. My 325i didn't come with OBC originally and only had the --:-- (or the time once I set it). Then when I bought an OBC stalk and re-coded the car for it I had all the other options. If you have access to DIS, PA Soft or some other software to do it, you can recode it. Personally I used DIS v44 to do it.

Maybe have it recoded, using PA soft is the cheapest way that I can think of, that's how I added the OBC in my car.
