Mazda CX-5 Service & Repair Manual: Evaporative Emission (Evap) Control System
Purpose, Outline
-
Prevents release of evaporative gas into the atmosphere.
-
The intake manifold vacuum introduces evaporative gas to the intake manifold via the charcoal canister and the purge solenoid valve.

DSC HU/CM
Outline
A high reliability, reduced size and weight DSC HU/CM, integrating both the
DSC HU and the DSC CM, has been adopted.
DSC HU Part Purpose/Function
According to DSC CM signals, the DSC HU controls (on/off) each solenoid valve
and the pump motor, adjusts fluid pr ...
DSC HU/CM Removal/Installation
WARNING:
If the DSC HU/CM configuration is not completed, it could result in an unexpected
accident due to the DSC being inoperative. If the DSC HU/CM is replaced, always
use the automatic configuration function so that the DSC operation conditions
are correct.
If the DSC re ...
