What U1411 code means?


U1411 Implausible Fuel Volume Signal ReceivedPossible Causes Setting Conditions
CAN 'C' Bus circuit is open or shorted to ground
Cluster module has failed
FCM has failed
PCM has failed
Key on or engine running; and the PCM determined that the Fuel Volume signal it received was implausible.
This code sets in 1 Trip(s).
This code will turn on the MIL (Malfunction Indicator Lamp) Vehicle Application: 2005 Jeep Grand Cherokee Laredo 4.7L, Vin N, Eng Cfg V8

Customer Concern: Has 11 codes. U0101, U110C, U0121, P0480, U1120, U0103, U1411, U110E, P000B, U0100, U0002. At this time there is a no crank condition.
Tests/Procedures: 1. Clear the codes and see what comes back. These are all communication codes.
2. Disconnect the modules one at a time when it is acting up and see when the communication comes back.
Potential Causes: Controller Area Network (CAN) C Module

Tech Tips: On this vehicle it turned out the Occupant Restraint Controller (ORC) which is on the Controller Area Network (CAN) B bus was actually causing the problem. It was also taking down the Controller Area Network (CAN) C bus at times. I hope this helps.

Jeep Grand Cherokee 2005 4.7L, CODE U1411 & U110A(or U11OA).Thanks.


https://www.techauthority.com/en-US/Pages/Home.aspx
page 4519,
the book covers that 100%

is this off a real scan tool or off dash. or what?
U codes.
wk jeep.
U1411 U1411-IMPLAUSIBLE FUEL VOLUME SIGNAL RECEIVED
U110a (yes that is a zero)
U110A-LOST COMMUNICATION WITH
SCCM - CAN C. . . . . . .
CAN B BUS CIRCUITS OPEN OR SHORTED
DTCS RELATED TO BATTERY VOLTAGE, IGNITION, OR VIN MESSAGES
FCM NOT CONFIGURED CORRECTLY
STEERING CONTROL MODULE POWER AND GROUND
STEERING CONTROL MODULE
MODULE THAT SET THIS DTC

bad communications, between the many computers.

the dealer scan tool can find this. most others not.
make sure battery is fully charged, reset the DTC errors with any scan tool and see if it comes back.
if it comes back and battery is still charged, then its real.

Code u1411 jeep liberty 2006


wow , no engine options stated, or type of driveline.... wow.
this is covered in the FSM, read that.
it states
U1411-Implausible Fuel Volume Signal Received that means to get the car fully scanned,
using a real scan tool that sees all 2006, jeep DTC errors.
including BCM codes.
the manual tells you what to do.

here is just small expert from the Factory.serv.manual

quote
Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding. (Refer to 9 - ENGINE - DIAGNOSIS AND TESTING)(Refer To List 1).
Theory of Operation
The BCM has to send the PCM a fuel volume signal over CAN C. The signal the BCM sends over CAN C is implausible.
Diagnostic Test
1. ACTIVE DTC
Ignition on, engine not running.
With a scan tool read DTCs.
Is the DTC active at this time?
Yes
  • Go To 2
No
Refer To List: 2. CAN C BUS DTCS ALSO ACTIVE
With a scan tool check for DTCs in the BCM.
Are any CAN C related DTCs active at this time?
Yes
  • (Refer to 8 - ELECTRICAL/ELECTRONIC CONTROL MODULES - DIAGNOSIS AND TESTING) for the appropriate diagnostic procedures.
  • Perform BODY VERIFICATION TEST - VER 1. (Refer to 8 - ELECTRICAL/ELECTRONIC CONTROL MODULES/FRONT CONTROL MODULE - DIAGNOSIS AND TESTING)
No
--------------------------------------------------------------------------------------------
that word CAN , means the vehicle network communications buss called CAN.
if the PCM can not TALK to the BCM. this can cause the
data to be wrong. and the
Implausible , data.
greek ,huh,
get it serviced by any ASE shop in town or if desperate JEEP.
