Vehicle: 2013 Lincoln MKZ. Have you ever had trouble with the electrical system on a newer Ford? It's possible the Battery Monitoring System needs to be reset. In this Diagnostic Quick Tip, National Field Trainer Jason Gabrenas shows you how to reset the system using a scan tool.
Starting with the 2011 model year, Ford and Lincoln vehicles use what's called a battery management system and what that does is it'll help conserve the battery's power.
Say you have got the radio on for a long period of time or something like that, it'll turn off some accessories to try and conserve that power.
Now you can either let the system sit for eight hours to reset itself or you can force it with a scan tool. I'm going to show you how to go through it using the scan tool to save that eight hours.
We already have the vehicle loaded in here, so we're just going to go into the Scanner. and that [the test] is located inside the Body Control Module so we'll go there. It is a Functional Test and it's right under Battery Monitor System Resets. We just go in there.
It wants to have the ignition on; the ignition is already on so we're good to go there and hit continue.
Then it's going to tell you when it needs to be done. So it needs to be done either when the battery's replaced, the BCM is replaced, or when you're instructed by the workshop manual.
And that'll be that case where if you left the key on and the radio doesn't work anymore, something like that, because it shut it off, you'd have to go in there and do that function as well.
So we'll just hit continue. It's going to cycle through the test. Tell us the test is complete and we're done.
That was pretty quick. A couple of seconds will save you eight hours of letting that battery sit.
