Solenoid Test (Inlet Valves)

SOLENOID TEST (INLET VALVES)

This test allows the technician to place individual inlet valves into a pressure-hold position by activating its corresponding solenoid with the Scan tool. When in the pressure-hold position, the valve will not allow hydraulic pressure to the wheel circuit.
During an ABS event, the control module activates an inlet valve solenoid when it detects that a wheel is rotating too slow.
