U0414Invalid Data Received From Four-Wheel Drive Clutch Control Module
- Generic OBD-II code · Network
- Turns on the check-engine light
- Can trigger limp mode
- How the car detects it
- U0414 is set when a listener, usually the engine controller, receives frames from the four-wheel-drive clutch control module but cannot trust what they carry. That module regulates an on-demand coupling feeding torque to the secondary axle and reports its state on the bus. GM's 2025 ECM tables (25OBDG03B) test the secondary-axle signal every 12.5 ms for faulty rolling counters, protection values or checksums; 8 errors among 18 checks, with at least 11 V and 5 s of stable operation, record a Type B fault, which lights the MIL on a second faulty trip. Ford's 2014 code interpretation also marks U0414 as a MIL code. Lost contact with the module is U0114, a software mismatch U0314. Expect an AWD warning and drive on the primary axle until the data are valid again.
