Mazda CX-5 Service & Repair Manual: Driver Side Air Bag Module [Standard Deployment Control System]
Purpose
-
When the driver-side air bag module receives an impact from a frontal or frontal offset collision, the operation (deployment) of the air bag mediates the impact to the head and face of the driver.
Function
-
When the driver-side air bag module receives an impact from a frontal or frontal offset collision, the air bag is operated (deployed) by the operation signal sent from the SAS control module.
Construction
-
The driver-side air bag module is installed to the center area of the steering wheel.
Operation
Inflator operation
-
The driver-side air bag module operates (deploys) the air bag by activating the internal inflator.
-
The inflator operates (deploys) in the following order:
1. When an operation (deployment) signal is received from the SAS control module, the igniter built into the inflator generates heat and ignites the ignition agent.
2. The ignition of the ignition agent causes the combustion of a gas generating agent which forms nitrogen gas.
3. The nitrogen gas is cooled at the filter and the filtrate is injected into the air bag.
Fail-safe
-
Function not equipped.

Purge Control
Outline
An appropriate amount of evaporative gas is fed into the intake manifold
by the purge solenoid valve operation according to the engine operation conditions.
This ensures driveability and prevents release of evaporative gas into the atmosphere.
The PCM drives the purge so ...
