AI DamageU0104 code: Lost Communication With Cruise Control Module
Code U0104 is named in 6 US owner complaints. Models: 4, model years 2017–2023.
What the code means
Lost Communication With Cruise Control Module. Generic meaning per SAE J2012 (the same for all makes).
How to read U0104: the letter U means network communication between modules; the second digit 0 marks a generic SAE code shared by all makes; the last three characters 104 identify the specific fault.
Codes for cameras, radars, blind spot and parking sensors. These units sit in bumpers, grilles and mirrors, so even a light impact shifts them or breaks mounts. After bumper or windshield work they need calibration on a rig, which is a separate and noticeable cost.

What owners report
Excerpts of owner complaints in the original wording. Owner statements not verified by the regulator; personal data removed.
I disconnected the battery ground cable from the chassis for 15 min and reconnected, but the errors come back on instantly once the van is started up. With my OBD scanner, there is a code being set U0104-00. I have not paid yet to have the van inspected formally by the dealer.
The vehicle was taken to the dealer, where a transmission flush was performed; however, the failure persisted. The dealer performed a diagnostic scan and retrieved DTC: U0104 and U0104-00. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 56,200.
Next time the vehicle starts, sometimes they are gone, then come back while driving, other times they are there from the start. U0104(00) [0xC10400] Data bus, cruise control module - no communication
