System context
Where this product sits in the control chain.
Manage trailer ride height, load-dependent pneumatic state and auxiliary-axle operation while preserving the intended braking architecture.
Suspension pressure, height or load input, electrical command and configured axle logic.
Lift or lower command, suspension air delivery or an output representing trailer load state.
Application decision record
What must be confirmed.
The review separates selection, installation and field evidence so responsibility and open points remain clear.
Selection inputs
- Axle count, suspension layout and lift-axle operating sequence
- Mechanical linkage geometry or electrical command logic
- Pressure, voltage, port and connector interfaces
- Automatic, manual and override behaviour required by the vehicle
Installation review
- Confirm ride-height datum and linkage travel without over-centre movement
- Verify hose routing through full suspension and steering travel
- Check raised and lowered axle states at relevant loads
- Protect electrical interfaces and confirm fail-state behaviour
Service evidence
- Loaded and unladen suspension-pressure observations
- Valve, cable or linkage position in each operating state
- Axle raise/lower sequence and delay
- Recent suspension, alignment or ride-height changes
Verification focus
Four checks that deserve an explicit record.
