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.

Hello, I have a problem with my Saturn Astra 2008,


U0121 Lost Communication With Electronic Brake Control Module

As with most trouble codes, the U0121 code gives a general diagnosis. Review the info on this link. Look through the service bulletins. The problem could be a loose plug or faulty wiring to one of the modules or between modules that are listed in the article. I hope this helps somewhat. Good Luck......

Hi there:
DTC U0121 - Lost Communication With Anti-Lock Brake System (ABS) Control Module


If the fault come back again, this is being caused by a failed ABS module. You will need to replace the module and run the verification process to correct your concern. To run the verification process you will need access to a full level scan tool (as factory scan).


Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day.

Same problem. ABS light, Brake ligth. Speedometer not working. I un hooked the nbattery for a while and all seem to be woring for now? Any ideas


Hi these trucks are know for the front hub bearings to fail., the wheel speed sensor is located in side of them and serviced as a unit. Mostly the set the abs light while doing slow turns your will hear the abs motor and feel the break pedal pulsate.

Abs light, brake light, engine light stay on but do not flash


Well, that sucks, for sure. The only commonality I can see between the engine, abs, brake light and speedometer is possibly a bad vehicle speed sensor. But when you throw in the codes for lost comm and cluster error, that muddied the water a bit. I am sure that there are separate fuses for the trailer wiring harness (my 04 chevy has separate fuses, surely an 09 dodge does) so I doubt trailer wiring could have done all this. A lost comm could be caused by a blown fuse. I would inspect every single fuse I could find in the entire vehicle, also, I have researched your problem a bit and have found a couple possible fixes. One is that the abs sensor on the rear differential is known to be sketchy and needs to be changed. The other is cleaning any ground cables that are connected to the fuse box on the front left fender. I hope this helps!

Speedometer stoped working ,at first sometimes it worked sometimes did not now wont work at all,allso abs and brake and motor light on when speedo wont work,2001 dodge ram 4x4 with 360 engine


Probably either your PCM or Vechile Speed Sensor. The VSS sends an AC (alternating current or sine) wave to the PCM and according to the frequency of the wave, tells the PCM the speed with which the vehicle is moving. It will be mounted to your transaxle, and I would look into this before the PCM.
