Does that mean that they are still present? Or they were fixed? This are all the codes that were stored when they changed the battery
U0101-LOST COMMUNICATION WITH TCM
For a complete wiring diagram, refer to the Wiring Information.



  • When Monitored:
    • With the ignition on.
    • Battery voltage between 10 and 16 volts.
    • Ignition Off Draw (IOD) fuse installed.
    • Totally Integrated Power Module (TIPM) is configured correctly.
  • Set Condition:
    Bus messages not received from the Transmission Control Module (TCM) for approximately 500ms.

Possible Causes
CAN BUS CIRCUITS OPEN OR SHORTED​
DTCS RELATED TO BATTERY VOLTAGE, IGNITION, OR VIN MESSAGES​
TOTALLY INTEGRATED POWER MODULE POWER AND GROUND​
TIPM NOT CONFIGURED CORRECTLY​
TOTALLY INTEGRATED POWER MODULE (TIPM)​
MODULE THAT SET THIS DTC​

U0415-IMPLAUSIBLE DATA RECEIVED FROM ABS
For a complete wiring diagram, refer to the Wiring Information.

Theory of Operation


The messages sent on the CAN bus are distinguished by an identifier (ID). Each CAN ID is defined to contain a certain number of bytes. The Transmission Control Module (TCM) verifies that it has received the proper number of bytes for each ID.





  • When Monitored:
    Continuously with the ignition on, one valid CAN ID received at least once, and no U0002-CAN Bus Off Performance DTC present.
  • Set Condition:
    When the TCM detects an incorrect CAN ID from the ABS control module.

Possible Causes
FCM CAN BUS DTCS PRESENT​
ABS DTCS PRESENT​
TRANSMISSION CONTROL MODULE (TCM)​

If the codes are no longer present or stored and have been erased....it's possible the battery was causing your issues.

The first two are concerning as outlined above. I don't have info for the others but looking up some of them it seems they're all electrical related codes. One refers to the passenger seat recline, another is liftgate related, another is Park Sense related, etc.

If you're still getting a check engine light then bring it in to see what the current stored codes are.

Those codes were stored before they replaced the battery. I haven't check if they are still stored since the new battery was put in place. But p0018 still comes up. Ima end up taking it to them again when the cel comes back on.

Hey people. So on friday they put a new pcm. Today sunday the check engine light came back. I will be doing a claim since i have the used car warranty to return the car. Now once i return this durango i am not sure if i will be picking a new durango or go with the cx9. Lets see.

The new pcm came after they replaced the battery, camshaft and crankshaft sensors. Not trusting this vehicle anymore.
