Pressure Transducers

9105-14 Fig. 5 - Pressure Switch And Pressure Transducer Wiring:

Two pressure transducers are used for brake system fault detection. Both transducers generate a voltage signal (between 0.25 volts and 5.0 volts) which is proportional to pressure. These signals are compared by the (CAB) and used to detect brake system faults that would require ANTI-LOCK braking to be disabled.

Fig. 2 - Hydraulic Assembly:

The boost pressure transducer is mounted on the bottom of the hydraulic assembly, see (Fig. 2) and monitors booster servo pressure. The primary pressure transducer is mounted on the left side of the hydraulic assembly and monitors primary master cylinder pressure, see (Fig.2).
