U3000Control Module
- Generic OBD-II code · Network
- How the car detects it
- U3000 is the catch-all for a fault inside the module that stores it; the attached failure-type byte says what kind. GM's front camera module uses :41 checksum, :42/:44 memory, :49 internal electronics and :51 not programmed, all without MIL, and then drops adaptive cruise. In a GM brake module the same code covers hardware self-tests and is Type A, while Ford's 2014 Boss 302S list marks U3000 in the PCM as MIL-relevant. Ford SSM 47982 notes that the cruise module of 2017–2019 Super Duty trucks can log U3000:49 after a weak battery: if it stays away after clearing, the module is kept. Mazda (15-002/19) replaced forward cameras that stored a permanent U3000:04. The module named in the scan matters more than the code.

- PossibleModule software or calibration that needs an update or reprogramming
- PossibleReal internal defect such as memory or processor failure in the module
- RareModule running too hot, e.g. a windshield camera in strong sun
