Solenoid valves SLU, TCM FA 57 (531)
| Solenoid valves SLU, TCM FA 57 (531) | 
| Main use | 
To regulate the oil pressure to the lock-up clutch.
| Type | 
Electromagnetic, PWM governed.
 
   
   | Activation | 
The solenoid is governed from pin 25 (B) on TCM using a 300Hz PWM signal. Grounding takes place on pin 12 (B) on TCM. The current varies between 0-1000 mA. The solenoid is closed when current is not applied. 0A = low oil pressure 1000mA = high oil pressure.
| Pin no. | Interface | Description | 
| 25 (B) | 300Hz PWM voltage | |
| 12 (B) | ground |
