Troubleshooting Guide
- Valve does not shift or responds slowly: Check solenoid coil for burnout or open circuit; check power supply voltage; check for contamination causing the spool to stick.
- Internal Leakage: Worn spool or seals, or contamination causing improper sealing.
- Valve sticking: Often due to inadequate fluid cleanliness, insufficient lubriion, or internal damage.
- Excessive noise: Can be caused by excessive vibration, voltage fluctuations, or issues with the solenoid.
- No function despite signal: Check the amplifier (for 4WRA), wiring, and connections between the control unit and the valve.
Maintenance Requirements
- Regularly check the solenoid coils and valve spool for wear.
- Maintain fluid cleanliness to prevent contamination, which is a primary cause of valve failure. Ensure the filtration system is functioning properly.
- Periodically inspect electrical connections and seals.
