Code U0141 on the 2022 Dodge Durango indicates lost communication with a front control module. This module, sometimes called the Front Electronic Module (FEM), manages front body functions including headlights, front door functions, and potentially front sensor inputs.
Front Control Module Functions
The front control module handles lighting control for headlights, fog lights, and daytime running lights. It may also manage front door lock and window circuits, rain sensor input, and communicate with the main BCM to coordinate vehicle-wide functions. Some configurations use it as a sub-network controller for front-end components.
Symptom Pattern
With U0141 present, front lighting may malfunction - headlights may not turn on, automatic headlight control fails, or lights behave erratically. Front door locks or windows may not respond to commands. Rain-sensing wipers may not function. Dashboard warnings indicate communication faults.
Diagnostic Approach
The front control module is typically located in the engine compartment or behind the front fascia area. This location exposes it to heat, moisture, and potential damage from collisions. Check power and ground supplies to the module. Inspect the connector for corrosion from moisture exposure. Verify CAN communication is reaching the module.
Repair Path
Many front module issues result from connector corrosion or wiring damage due to the exposed location. Clean connectors and repair damaged wiring. If the module has failed internally, replacement requires programming with Stellantis diagnostic equipment.
