07 chevy uplander LS,3.9l v6,54,000mi.
It has 2 messages on the dash comp. Service vehicle soon and battery saver active.I had the alt tested off the vehicle and it was good.Took it to the local chevy dealer and they pulled the B1390 code,cleared it and it instantly came back on.Any info would be appreciated.
Thanks,Lee

B1390 is not a valid code for that vehicle. You probably want to have it read again.

It is not a good code for that vehicle.

Just curious, but why didn't the dealership diagnose the problem? Or was it intermittent when they had it? I don't see a listing of that code either, but it probably has something to do with the power sliding door system.

The battery saver is active because the module that controls the charging and power distributor system saw the battery level was lower that 10.9 volts along with more than 12AH of battery power consumption. The module will reduce the electrical load by turning things off or shedding the electrical system. If you leave the ignition turned on with the engine off for a long period of time with accessories running, the battery saver system probably will activate.

I have found the code & description online.They said app 3 hr to figure out why at $80.00 /hr.Then poss fix it.I figure there is someone who has had the same problem out here somewhere. The battery saver comes on while driving it.Lights flicker blowers fluctuate,no power doors.

Do your power sliding doors operate?

I suppose you believe everything you read online........

The factory service manual does not list that code as applying to that vehicle so you have to have the wrong code.

I told you that code was not programmed into your operating system. Did you think I just made that up? Don't bother trying to answer. You already realize your access has been removed.
