DACMC - 2.3L

WARNING: This page is about a different car, the 2018 Ford Focus. However, it is still accessible from the selected car via links, so may be relevant.

The DACMC ESE functions only operate while the engine is running.

The DACMC is a digital signal processor that consists of an internal analog/digital converter and tone generator.

The DACMC uses engine rotation speed data, engine torque data, and accelerator pedal position data from the PCM to calculate the targeted frequency needed to enhance engine noise within the passenger compartment. The DACMC ESE frequency signals are output to the audio DSP module as fluctuating AC voltage. The audio DSP module sends the signal to the LHF, RHF, RHR, and LHR door midwoofer speakers as fluctuating AC voltage.

The DACMC requires PMI when it is replaced.
