System Operation: ESE
WARNING: This page is about a different car, the 2018 Lincoln MKC. However, it is still accessible from the selected car via links, so may be relevant.
ESE is an audio system feature that enhances certain engine tones typically induced under wide open throttle or heavy part-throttle conditions. The system uses a DACMC (contained within the ACM) and the audio system speakers.
The DACMC determines the engine tone to enhance based upon engine rotation speed data, engine torque data, and accelerator pedal position data from the PCM. The data from the PCM is processed and converted into an analog audio signal, transmitted to the DACMC internal tone generator, and output by the ACM to the LHF and RHF door midwoofer speakers as fluctuating AC voltage.
