U2014 - Audio Control Module Hardware Component Failure
U2014 Possible Causes
- Faulty Audio Control Module (ACM)
- Audio Control Module harness is open or shorted
- Audio Control Module circuit poor electrical connection
How is the U2014 code repair?Start by checking the "Possible Causes" listed above. Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector's pins.
U2014:09 (Control Module Hardware: Component Failure) The DTC sets when the ACM detects a fault in the internal gyroscope. The gyroscope is not serviceable.
What is the cost to diagnose the U2014 code
Labor: 1.0The cost to diagnose the U2014 code is 1.0 hour of labor. The auto repair's diagnosis time and labor rates vary by location, vehicle's make and model, and even your engine type. Most auto repair shops charge between $75 and $150 per hour.

U2014 MeaningDigital signals are received by the satellite radio antenna and sent to the Audio Control Module (ACM) through the satellite radio antenna cable. The satellite receiver is internal to the ACM. When a satellite radio subscription is activated, the Electronic Serial Number (ESN) of the built-in satellite receiver is associated with the Vehicle Identification Number (VIN). As a result, the ACM cannot be swapped from one vehicle to another. If there is an open in the satellite radio antenna circuit, there is no satellite audio. The audio system display indicates a satellite antenna concern when the audio system is operated in satellite radio mode.
The primary source of vehicle location for the navigation system is the Audio Control Module (ACM) receiving the position signal through the Global Positioning System (GPS) antenna (integral to the satellite radio antenna). In addition, the ACM receives the navigation rolling wheel count signal from the Instrument Cluster (IC) (which gateways the signal from the ABS module). This secondary signal is used to calculate vehicle position when the GPS signal is lost. It also supports the adaptive learning function of the ACM, whereby the ACM can compensate for long-term differences between the GPS signal location and the actual distance traveled by the vehicle.
