Solenoid Valve SLC2, TCM AF 40 (531)

Solenoid valve SLC2, TCM AF 40 (531)

Location
The solenoid valve is mounted in the gearbox valve housing.

Main use
The valve controls the pressure in clutch C2. The valve is active in gear positions P, R, N, D (gears 1, 2 and 3).

Type
Electromagnetic, variable PWM). controlled.





Activation
The control module activates the valve by pulsing it with B+ (300 Hz PWM). The valve is powered from control module pin 17 in the connector that makes contact directly with the gearbox on the bottom of the control module. The valve is grounded from pin 18. The current varies between 0 - 1000 mA. The solenoid is normally open and the hydraulic pressure drops as the current increases.
