U2014 Code - Audio Control Module Hardware Component Failure

Quick Answer

Digital signals are received by the satellite radio antenna and sent to the Audio Control Module (ACM) through the satellite radio antenna cable. Common causes include Faulty Audio Control Module (ACM), Audio Control Module harness is open or shorted, Audio Control Module circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code U2014 Description

Digital 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.

Code Tech Notes

U2014:96 (Control Module Hardware: Component Internal Failure) The Diagnostic Trouble Code (DTC) sets when the ACM detects an internal fault to the built-in satellite radio receiver. This results in a complete loss of satellite radio functionality.
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 Code?

Labor: 1.0

To diagnose the U2014 code, it typically requires 1.0 hour of labor. Rates vary by location, vehicle, and shop. Many shops charge between $80–$150 per hour; dealerships and metro areas may be higher, independents may be lower.
