High Speed CAN Communication Bus

…The vehicle returned to Pep Boys, where DTCs U0001 (CAN C Bus) and U0401 (Implausible Data Received From ECM/PCM) were documented. It then went to a Chrysler dealership in Florida. They evaluated it and told us it checked out and was okay to drive. After leaving that dealership, the problem returned while my family and I were traveling at highway speed. The vehicle malfunctioned and began losing acceleration. I exited the highway. When I stopped at a stop sign, the vehicle died. It restarted but again would not shift. Eventually we were able to reach a nearby gas station. The problem continued intermittently as we tried to get home. Because we could not predict when it would happen again, we…

When I was driving the gear shift into Netural, all lights on gear shift were lit up red (Park, Reverse, Netural, Drive). The message said “Press brake, Put car in P, Select Gear”. This is so scary because it has happened twice to me. When I took to Midas as soon as it happen, since they were open. The ran a code that read U0001, and read that this is a power train issue. And informed me to take to the dealership because it should be covered for the recall that’s in these models. While driving on highways I have had to put car on side of road to keep from a crash. This is a real hazard and safety concern.

THE SEAT BELT INDICATOR STAYS ON. CODE U0001 ONLY OCCURRED AT IN & OUT INSPECTIONS. CODE U1504 STEERING ANGLE SENSOR 3/2020.

THE STEERING COLUMN STARTING MAKING A LOW PITCHED WHINING SOUND FOR THE PAST 4 MONTHS. THE CAR WAS STOPPED AND PARKED AND THE WARNING CAME ON ABOUT THE SERVICING THE POWER STEERING AND NOW THE CAR HAS NO POWER STEERING. CODES: U11E8-00- & U0001-00- AND THE CAR IS NOW 1500 MILES BEYOND THE WARRANTY. WE ARE GOING TO PUSH TO THE GET THIS FIXED UNDER WARRANTY BUT AT 37K MILES THIS SHOULDN'T HAPPEN, AND AFTER RESEARCHING ONLINE THIS APPARENTLY IS A COMMON PROBLEM WITH THE POWER STEERING MODULE LOCATED ON THE THE RACK AND PINON AND THE WHOLE THING WILL HAVE TO BE REPLACED. THIS SHOULD DEFINITELY BE A RECALL AS THIS IS A MAJOR SAFETY HAZARD.

While driving all sensors began flashing simultaneously. I took to mechanic and a few codes turned up. One for speed messages. One for can bus and the other was U0001. Took to dealership service and they had it for a week. After charging battery all sensors were cleared. Same day driving home all sensors came back on simultaneously. Car began making noises and driving in limp mode windshield wipers turned on by themselves. Took car to Firestone to check battery. They replaced battery. Sensors were still flashing all the way home but no other problems. Next day i lost power steering and ability to brake. Nearly crashing the Durango. I eventually was able to pull wheel and get to side of road…

SO - I'VE GOT A 2013 500E AND IT STARTED DOING THIS LAST WEEK OR SO. THE RBC, THE ESC, THE ABS, AND EVEN THE HILL ASSIST TRANSIENTLY, AND ONCE OR TWICE EVEN WENT INTO 'PROPULSION SYSTEM SERVICE' ERROR MODE AND WOULDN'T RUN. AFTER A RE-START IT WOULD THEN RUN. EVEN DID THE BATTERY TRICK. NOT SURE IF IT HELPED OR NOT. SO, I DECIDED TO DO THE OBD2 - WITH THE KONNWEI AND THE ALFOBD - FULL PROGRAM - AND IT WAS ABLE TO CLEAR THE CODES AND PULL UP THE ERRORS : U0001, U1201, U1487 - AND EVEN THOUGH IT RECURS AND I FEEL A CLICK AND CHANGE IN BRAKING WHEN THE RBC LIGHT GOES OFF, AND THE ESC LIGHT, AND EVENTUALLY THE ABS LIGHT TOO, AND IT STARTS MAKING FUNNY NOISES FROM THE BRAKES WHEN STOPPED AND…

…In this order U0121 U1110 U1120 U11BC U12AB P057C (Brake Pedal Sensor Circuit Low) U11BF U0001 High Speed Can Communication Bus P0000

The check engine light and a (A)! light with "service auto/start stop" came on at the same time with no symptom of any issue being immediately noticeable. The Parking break "BRAKE" light on the dash light up for half a second. Then the transmission was stuck in 7th gear and would not downshift on its own. When pulling on the wheel's paddles a "shift denied" message was deplayed despite the fact i was going 10mph in 7th gear. Check engine light code was P076F and U0001 and U1199. Upon driving the vehicle again Car this time transmission got into 8th gear and stated "shift denied" and wouldn't downshift from 8th gear for any reason. I parked it for a couple days. When trying to take it to the…

…THE ENGINE CODE IS U0001. IF I HAD BEEN ON THE FREEWAY WHEN IT LOST POWER, I WOULD NOT HAVE HAD TIME TO GET OVER TO THE SHOULDER AND COULD HAVE BEEN BADLY HURT OR KILLED IF I GOT HIT BY ANOTHER CAR.

I was driving down a side street when I received several warning lights for service shifter, airbags, seatbelts as well as the engine and all gauges cutting in and out. Following that my power steering went out and I could barely steer the vehicle. I had to call roadside assistance to tow the vehicle. The following fault codes wers pulled via obdii: U0001, U0151, U0155, U017E, U0418, U1442. Each code related to a malfunction with "CAN BUS C" or what the dealership referred to as a "star connector". After further research it is apparent that this part has continued to fail on many jeep wranglers dating back to 2018 and every report I have seen the person has stated the same issue of losing…
