Mazda CX-5 Service & Repair Manual: Awd Control Module

Mazda CX-5 Service & Repair Manual / Drivetrain / Driveline / 4WD / Awd Control Module

Purpose, Function

The AWD CM calculates the optimal amount of torque distribution for the rear wheels and outputs a corresponding electric current to the electronic control coupling (AWD solenoid). This calculation is based on the accelerator pedal angle, four-wheel speed, engine speed, and other related input signals, matched with the vehicle driving and road surface conditions.

Function table


Function name	Contents
AWD system control function	Based on each input signal, the electronic control current sent to the electronic control coupling (AWD solenoid) is optimally controlled.
Diagnostic system	If the self-diagnostic system detects a malfunction, the AWD warning light illuminates to alert the driver, and at the same time the system suspends control or performs other measures to prevent a loss of driving stability and protect the system. The detected malfunction is stored as a DTC in the AWD CM.

Construction

The AWD CM is installed to the right of the dashboard. (Passenger side)

Control Valve Body [Fw6 A EL, Fw6 Ax EL]
Purpose/Function The control valve body controls the hydraulic pressure generated by the oil pump by each solenoid valve. In addition, the oil passages which introduce hydraulic pressure to the pistons for each clutch and brake is formed by the switching of each built-in shift valve. ...

Turning the Engine Off
WARNING Do not stop the engine while the vehicle is moving: Stopping the engine while the vehicle is moving for any reason other than in an emergency is dangerous. Stopping the engine while the vehicle is moving will result in reduced braking ability due to the loss of power braking, which co ...
