Code U0104 on the 2022 Nissan Altima indicates lost communication with the cruise control module. This module manages conventional cruise control as well as Nissan's Intelligent Cruise Control (ICC) adaptive system if equipped.
Cruise Control System Architecture
The cruise control module receives driver inputs from the steering wheel controls and communicates with the ECM to manage vehicle speed. On vehicles with Intelligent Cruise Control, the module also processes radar sensor data to maintain distance from vehicles ahead. This communication fault prevents these functions from operating.
Observable Effects
With U0104 active, cruise control becomes inoperative - the system won't engage when the button is pressed. If equipped with ICC or ProPILOT Assist, these features are also disabled. A warning light or message appears on the instrument cluster. Basic vehicle operation including acceleration and braking remains normal.
Root Cause Analysis
The cruise control module may be integrated with other systems or standalone depending on vehicle configuration. Check the steering wheel control switches and their wiring first - stuck buttons or damaged clock spring connections can affect module operation. Verify module power supply and CAN communication. Radar sensor issues on ICC-equipped vehicles can also trigger this code.
Repair Path
Many U0104 codes result from steering column/clock spring issues rather than module failure. Test switch inputs and wiring before condemning the module. If the module requires replacement, Nissan CONSULT is needed for programming. ICC-equipped vehicles require radar sensor calibration after related repairs.
