Mazda CX-5 Service & Repair Manual: Engine Transaxle Integration Control [Fw6 A EL, Fw6 Ax EL]
Outline
-
The TCM controls engine output torque and reduces transaxle output shaft torque fluctuation during auto shifting, and reduces shock occurring from the vehicle during shifting.
Construction
Operation
-
During auto shifting, the TCM sends the torque reduction request signal using the CAN system and temporarily reduces the engine output torque by the engine ignition timing retard control. As a result, transaxle output shaft torque fluctuation is reduced during auto shifting by smooth engagement of the clutch.
-
In addition, the TCM receives the engine output torque from the PCM via the CAN signal to determine the clutch engagement pressure according to the engine output torque. As a result, the clutch hydraulic control setting accuracy is increased and smooth shift performance is achieved.

Magnet Clutch [Manual Air Conditioner]
Purpose
The magnetic clutch transmits the rotation force from the engine to the shaft
in the A/C compressor.
Function
The magnetic clutch engages or disengages the magnetic clutch and the A/C
turns on or off by switching the power transmission from the engine.

Generator Control [Skyactiv G 2.0]
Outline
Idling stability has been improved by optimum control of generator voltage
according to engine operation and electrical load conditions.
The PCM determines the engine operation and electrical load conditions based
on the input signals from each control part and controls ...
