ESE - 2.7L GTDI And 3.5L GTDI

WARNING: This page is about a different car, the 2015 Ford F-150. 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 audio DSP module as fluctuating AC voltage. The audio DSP module sends the signal to the LHF and RHF door woofer speakers as fluctuating AC voltage.

The ESE feature can be disabled (or re-enabled after disabling) through the use of programmable parameters and a diagnostic scan tool. For more information, Refer to: Module Configuration - System Operation and Component Description . See Module Configuration and Parameter Chart.
