Problems with 2007 Liberty instrument panel

Hey all,

I recently bought a used 2007 Liberty and I love it except for a few things. About 4 days after i bought it the check engine light came on. I took it to Advance Auto Parts to have the scanner hooked to it and it came back with a U1403 (implausible fuel level) Shortly thereafter it went off. Now as i'm driving around occaisonially the instrument panel will dim and show different warning lights such as BAS/EPS? ESP (traction control in the middle) and the check engine light came back on. When i shut the vehicle off all the lights go off except for the check engine light, and all seems to be working properly. I know little more than to change a tire check and change oil so any help would be appreciated.

That may not be the instrument panel itself, except the the panel going DIM...

If the EPS/BAS, ABS, and the SKID mark indicator come on, that means there is a problem with the system. Mine does it, and all them are on, STILL on (bad clock spring angle sensor). That's because either a sensor is bad, or the clock spring angle sensor is bad. If it comes on while you are driving, it is detecting an intermittent problem with the same areas; a sensor with intermittent readings, a short (rear mostly), tire rotation not matching front to back...

When I went on a trip to Missouri, on the way back, the jeep began to shudder and buck a little. I thought, OH GREAT, the transmission is going. Shortly after, all those lights came on. Then they would go off, then the same thing would happen again. So, when they went off, I pressed the button on the column for the ESP off, and it stopped all that shuddering and stuff from happening, and I was able to ride it with no incident; the lights remained OFF. For some reason, it was detecting wheel slip, and applying the breaks, then it realized there was an error, and let go, then flagged all the MILS accordingly.

What you do, when all the lights are off, press press the ESP OFF button, so the skid marks light up, then drive it, see what happens. That shuts the ESP off, so if it is a error in that area, the MILS won't come on.

I dunno why the CES light comes on... If you are getting implausible fuel level, check to see if the fuel pump was recently replaced. I was just at a shop a few weeks ago. They previously replaced the fuel pump in a Liberty, and the woman brought it back, while I happened to be there, for that problem. They fixed it, just a possible solution... It could also be a problem with the circuit at the tank... If the fuel gauge acts normal, who knows.

What sucks, is if one sensor is bad, ABS, BAS (Breaking assist), ESP, all get shut down, and none of it works once they all light up. They all depend on those sensor readings, exclusively.

I am having similar issues with my '06 Liberty Sport. Gascap indicator comes on despite having just replacing it, various warning lights coming on and going right back out, interior lights going on and off by themsleves and last night-I lost all dash lights for a few seconds and when they came back on-so did every warning light in my dash.

I lost the #2 position of my blower and was advised to replace the resistor. I am wondering if there is a short in there too. Will be replacing the blower resistor tomorrow. I wish you luck!

thanks for all the input powerslave. Let me clarify those lights just happened to stay on this time around they're usually random and nothing stays on whenever it does it with the exception of the check engine light. I guess it may be who of me to take it to the dealer and let them look at it. Little upsetting since i've only had it for roughly a week

ok guys i have something of a resolution, i replaced the BCM and discovered a faulty ground wire. Now every so often when i have my headlights on making a right hand turn with my turn signal the headlights flicker for just a second. Could this be the turn signal switch?
