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.

05 chrysler 300 code u1120 and u0121


Both of these have to do with the ABS system. U codes are lost communications codes from computers. Sometimes they are the wires. When you have different computers not communicating. Since yours are both from the ABS, I suspect the ABS module has died. Still could be the wire though (not likely). Check the wire for resistance. if good( less than 5 ohms) then the module has died. When you have ABS system malfunctions, the brakes revert back to the old system. Meaning if you hit the brakes to hard, they could lock the tires and have a skidding effect. BUT the brakes still work, they will stop the vehicle. Basically it is your call to have them fixed.

Code u1120 Lost Wheel distance what does this mean and how do I repair it?


U1120 means the abs module has lost communication with speed sensors. You'll need a scanner to monitor speed sensors. If problem is in module you won't get communication with scanner. Follow your brake lines from master cylinder to ABS pump/module, on the side of in is a wired connector. Undo it and check for moisture or corrosion. Get some dielectric gel and smear it good on all contacts. And plug back in and retest. Might need new module or speed sensor

U1120 The code U1120 means, lost wheel distance message. The powertrain control module(PCM) is not
receiving a signal from the anti-lock brake module. The problem could be a short in the bus circuit,
the PCM or the anti-lock brake module. This type of problem is best diagnosed by the dealer or a
local shop with the proper diagnostic scanning equipment. Hope this helps.

Engine light comes on problem code is U1120


U1120 means the PCM doesn't receive a vehicle speed signal from the Anti-lock brake Module over the CAN C bus. This can be caused by the ABS module, PCM or something wrong with the can bus. This might be just an erroneous code and may never set again

Dodge codes.


U codes are undercarriage codes, It can be possible that this code is directly related to a mistake done while the oil was changed. Although a description of the code will help a little more.
