I’ll try to be as quick and to the point as I can be while trying to be very descriptive; please bear with me. I’ve been having an issue with my Chrysler 300. The code it throws up is U1403.

Here’s what I know:

• U1403 «Implausible Fuel Level»

• As soon as I clear the code, it comes back.

• Pulling fuses and disconnecting the battery does not clear the code.

• From what I’ve read, it’s a communication code; The PCM is not receiving a fuel signal. The instrument cluster picks up information on the fuel level, and passes it along CAN B bus to the FCM, which passes it along CAN C bus to the PCM (if I understand that correctly).

• The fuel gauge works fine.

• MIL light is off, but code scanner says MIL is on. KOEO -> My check engine light works, so it can’t be an LED.

• At a glance, nothing behind the cluster seems unplugged.

• Sometimes when I insert the key in the ignition, for a split second the cluster lights go on — maybe this indicates an electrical problem?

• The battery in the car is new.

• Instrument cluster has no problem telling me what my range is, gas mileage is, how much fuel I have left, and so on.

Here’s what I’ve done:

• Made sure cluster was connected

• Made sure there were no gnarly/obvious disconnects

• Cleaned (sanded the surface) of ground wire connections; One in the engine bay by the jumping post, one behind the instrument cluster, one under the steering wheel. The wire in the trunk looks OK.

• Made sure PCM and FCM were connected and that all connections/pins were clean.

• Checked all of the fuses and made sure none of them were bad. In the front and the back of the car.

I was wondering if anyone has experienced this before. If so, what fixed it? What might be something I could try? Additional things that I think would help, if possible; Does anyone have some sort of diagram that shows what CAN B and C buses look like and where they’re found? I think everything from the fuel tank up to the instrument cluster is fine — is there a way to check if fuel level (that, specifically), is being sent over the wires away from the cluster? How about into the cluster?

Thank you all so much for taking the time to read this. This has been a really frustrating problem, considering the car seems to be perfectly fine but won’t pass emissions.
