U0414 Invalid Data Received from 4WD Clutch Control Module
The 4WD Clutch Control Module is present on the data bus but the values it reports are implausible — out of range, frozen, or failing the checksum or rolling-count check. The receiving modules reject the data. All-wheel-drive engagement becomes unreliable. Causes include a faulty sensor feeding the module, internal computation errors, a software or calibration mismatch after a repair, or bus interference corrupting the frames.
