Solenoid valves SLS, TCM FA 57 (531)

Location

Solenoid valves, TCM (531)





Main use

To regulate the oil pressure to the various clutches/brakes in the transmission.

Type

Electromagnetic, PWM governed.





Activation

The solenoid is governed from pin 26 (B) on TCM using a 300Hz PWM voltage. Grounding takes place on pin 36 (B) on TCM. The current varies between 0-1000 mA. The solenoid is open when current is not applied. 0A = high oil pressure 1000mA = low oil pressure.
