Mazda CX-5 Service & Repair Manual: Pressure Sensor [Two Step Deployment Control System]
Purpose
-
The pressure sensor determines at an earlier stage whether to detonate the air bag on the side of the vehicle (around front door) receiving an impact. This is for improved accuracy of the side air bag operation (deployment).
Function
-
When the vehicle is involved in a side-impact collision, the pressure sensor detects air pressure applied to the internal front door and sends an air bag deployment signal to the SAS control module.
Construction
-
A pressure detection sensor is built into the pressure sensor.
-
Located inside the center of the front doors.
Operation
1. If the vehicle is involved in a side-impact collision, air pressure is generated in the sealed front door and applied to the pressure sensor.
2. The pressure detection sensor built into the pressure sensor detects the pressure and converts the pressure into an electrical signal at the signal processing circuit.
3. The pressure signal, which is converted to an electrical signal, is sent to the SAS control module.
Fail-safe
-
Function not equipped.
