•  The PCM is located in the resonance chamber in the left-hand front wing.

•  The PCM monitors and processes the input signals from the sensors and compares these with stored parameters.

•  Using this information, the PCM calculates the output signals for triggering the actuators.

•  A diagnostics check can be carried out on the PCM via the DLC-II using Mazda Modular Diagnostic System (M-MDS).
