Pneumatic Lift Axle Control
Controls pneumatic axle lift mechanisms on multi-axle trucks. Raises unneeded axles when unloaded to reduce tire wear and improve fuel economy, and lowers them when loaded for legal weight distribution.

|---|---|
setMode(mode) | Directly switches the axle state by reconfiguring pneumatic valve targets. |
toggleMode() | Swaps between lifted and dropped axle states. |
module.setMaximumSupplyPressure(maxSupplyPressure) | Sets the maximum supply pressure. |
module.setMaximumSupplyPressureChangeRate(maxSupplyPressureChangeRate) | Sets the maximum supply pressure change rate. |
Hooks
| Hook | Description |
|---|---|
initLastStage(jbeamData) | Connects to the primary and lift pneumatic actuators and sets the default 'lift' mode. |
updateGFX(dt) | Dynamically adjusts maximum supply pressures and updates dashboard indicators for axle state and pressures. |

Cross-Flow Valve Controller
Controls pneumatic cross-flow valves that connect air springs on opposite sides or axles. Allows pressure equalization between air bags for improved ride quality or load sharing.
Low Air Pressure Warning
Monitors pneumatic system pressure and triggers dashboard warnings and audible alerts when air pressure drops below safe operating thresholds. Critical safety system for air brake equipped vehicles.
