Brake Fluid Pressure Sensor Function; Brake Fluid Pressure Sensor Construction; Steering Angle Sensor Function; Steering Angle Sensor Construction - Mazda 2006 MX-5 Service Highlights

BRAKE FLUID PRESSURE SENSOR FUNCTION

• The brake fluid pressure sensor detects the fluid pressure from the master cylinder and transmits it to the DSC
HU/CM.
End Of Sie

BRAKE FLUID PRESSURE SENSOR CONSTRUCTION

• The brake fluid pressure sensor is integrated with the DSC HU/CM. Therefore if there is any malfunction of the
brake fluid pressure sensor, replace the DSC HU/CM.
End Of Sie

STEERING ANGLE SENSOR FUNCTION

• The steering angle sensor, located on the combination switch, detects the steering angle degree and the
neutral position, and transmits these to the DSC HU/CM via CAN lines.
Warning
• The following circumstances will cause the stored initialization value of the steering angle sensor
to be cleared. This may possibly cause an accident due to the DSC becoming inoperative. Always
refer to the Workshop Manual and properly perform the initialization procedure for the steering
angle sensor so that the DSC operates properly.
— Negative battery cable disconnection
— Steering angle sensor connector disconnection
— Fuse (ROOM 15A) removal
— Wiring harness disconnection between battery and steering angle sensor connector
Note
• If the initialization procedure for the steering angle sensor has not been performed, when the ignition
switch is turned to the ON position, the DSC indicator light illuminates and the DSC OFF light flashes to
warn of a malfunction.
End Of Sie

STEERING ANGLE SENSOR CONSTRUCTION

• The steering angle sensor, integrated with the
combination switch body, has a sensor unit
straddling a disc that moves together with the
steering mechanism. Therefore, if there is any
malfunction of the steering angle sensor, replace
the combination switch body.
End Of Sie

DSC INDICATOR LIGHT FUNCTION

• The DSC indicator light, built into the instrument cluster, informs the driver of the following vehicle conditions.
— DSC is operating (vehicle side-slip)
— TCS is operating (drive wheel slipping)
