Pressure Modulator Valve (PMV) Pressure SW (W Traction Control)

The pressure switch monitors primary brake system pressure. The normally closed switch opens when the brakes are applied (pressure exceeds 700 kPa [101 psi]). If the brakes are manually applied during traction control mode, the Pressure Modulator Valve (PMV) pressure switch input, along with the brake switch input, signal the EBTCM to disable traction control and allow manual braking.
