The AccuAir e-Level+ system is a sophisticated air suspension control unit designed to provide precise and customizable ride height management for vehicles. This quick user guide outlines its primary functions, operational features, and basic maintenance procedures, including calibration and troubleshooting.

Function Description

The e-Level+ system allows users to control their vehicle's ride height with accuracy and ease. At its core, the system utilizes height sensors to monitor the vehicle's position relative to the ground, enabling automatic adjustments to maintain desired settings. It offers three savable ride heights, allowing users to quickly switch between preferred positions such as "Raised," "Ride Height," and "Lowered." This capability is particularly useful for navigating different terrains, parking, or achieving a specific aesthetic. The system also incorporates a RideMonitor™ mode, which, depending on its accuracy setting, continuously monitors and adjusts the vehicle's height to compensate for changes in load or road conditions, ensuring a consistent ride. An ActiveStart™ feature is also available, which can be configured to automatically adjust the vehicle to a pre-set ride height upon startup. The system includes a compressor status indicator, providing feedback on the air compressor's operation, which is crucial for maintaining air pressure in the tank.

Usage Features

The e-Level+ system is operated via a user-friendly touchpad, which features dedicated buttons for each of the three savable heights (1, 2, and 3), as well as individual controls for raising or lowering each corner of the vehicle. There are also "All Down" and "Program" buttons, the latter of which is central to accessing settings and initiating calibration.

Saving Heights: To save a new ride height, the user first manually adjusts the vehicle to the desired position using the individual corner controls. Once the desired height is achieved, the user holds down the corresponding position button (1, 2, or 3) for three seconds. The position indicator will flash and then become solid, confirming that the new height has been saved. This allows for quick recall of frequently used heights.

System Settings: The touchpad also provides access to various system settings. By momentarily pressing the "Program" button, users can enter the settings menu. Here, adjustments can be made to features such as "Backlighting Increase" and "Backlighting Decrease" to control the brightness of the touchpad's illumination. The "Ride-Height On-Start" setting determines whether the vehicle automatically adjusts to a specific height when the system is powered on. The "RideMonitor™ Mode" can be toggled on or off, and its accuracy level can be set to one of three options:

• Accuracy #3 (Most Accurate & Most Adjustments): Provides the most precise height control with frequent adjustments.
• Accuracy #2 (Factory): The default setting, offering a balance of accuracy and adjustment frequency.
• Accuracy #1 (Less Accurate & Fewest Adjustments): Offers less precise control but with fewer adjustments, potentially suitable for certain driving conditions or preferences. The "ActiveStart™" feature can also be enabled or disabled, and the "Tank Pressure Setting" allows users to define the desired air tank pressure.

Individual and Paired Controls: The touchpad includes distinct sets of arrows for "Front Controls," "Rear Controls," and "Individual Controls." The "Paired Controls" allow for simultaneous adjustment of both front or both rear wheels, while the "Individual Controls" provide granular control over each corner of the vehicle, enabling precise leveling or custom stances.

All Down Feature: The "All Down" button, when held for 5 seconds, will fully lower the vehicle, providing a convenient way to achieve the lowest possible stance.

Downloadable App: For enhanced control and additional features, the e-Level+ system supports a companion mobile application. Users can download and install the "e-Level+ APP" from the Apple App Store or Google Play Store, extending the system's functionality to their smartphone or tablet.

Maintenance Features

The e-Level+ system requires calibration, especially if height sensors are used or if any suspension components are changed or replaced. Calibration ensures that the system accurately reads the vehicle's height and can make appropriate adjustments.

Calibration Procedures:

• Automatic Calibration: This is the initial calibration process. To perform it, the user holds the "Program Button" and "Position 1" button simultaneously until calibration begins. During this process, the vehicle will automatically raise and lower to learn the sensor travel and suspension parameters. It is crucial that the vehicle is parked on level ground and clear of any obstructions during this procedure, as the vehicle will move significantly. This calibration is essential for the system to understand the full range of motion of the suspension.
• Recalibration “LITE”: If the system has already been calibrated, a "LITE" recalibration can be performed by holding the "Program Button" and "Position 2" button simultaneously until calibration starts. This process retains previous range and height settings while continuously improving the system's accuracy. It's a quicker way to fine-tune the system without going through the full initial setup.
• Manual Calibration: For users who wish to manually define the maximum travel, a manual calibration is available. This is initiated by holding the "Program Button" and "Position 3" button simultaneously until calibration begins. The user must first raise the vehicle to its maximum safe travel position before starting this calibration. While it is a full calibration, it provides the flexibility to set the maximum travel according to specific preferences or vehicle limitations.

Error Codes and Troubleshooting: The system is equipped with a diagnostic feature that indicates errors through flashing patterns on the position buttons and color changes in the corner arrows. This allows users to identify and address issues promptly.

• Flashing Trouble Codes: All three position buttons flashing simultaneously indicate a general error. Specific flash patterns correspond to different issues:
  • 2 Flashes: Tank pressure is not increasing as expected. This suggests a problem with the air supply. The recommended action is to verify that all tank ports are plugged.
  • 3 Flashes: Height sensor travel is too small during calibration. This indicates that the sensors are not detecting sufficient movement during the calibration process. The user should re-check sensor travel.
  • 4 Flashes: Pressure sensor not detected. This means the system is not receiving input from the pressure sensor. The user should check that the pressure sensor is connected.
  • 5 Flashes: Sensor corner association error. This implies a problem with how the sensors are linked to specific corners of the vehicle. The user should verify correct plumbing and sensor wiring.
• Corner Error Indication: The corner arrows on the touchpad can also turn red to indicate sensor or valve errors.
  • A single RED up or down arrow on a corner suggests a non-functioning valve or a mechanically disconnected sensor.
  • If both the UP and DOWN red arrows on a corner are red, it indicates that the sensor is either not connected or is not reading as expected electrically.
• Up or Down Strobing Red Arrows: These strobing patterns provide information about the vehicle's voltage:
  • If the red arrows are strobing UP, it signifies that the vehicle voltage is ABOVE 16 volts.
  • If the red arrows are strobing DOWN, it indicates that the vehicle voltage is BELOW 10.5 volts.

These detailed error codes and indicators empower users to diagnose and potentially resolve common issues, or to provide specific information to AccuAir Tech Support for more complex problems. Regular calibration and attention to error codes ensure the optimal performance and longevity of the e-Level+ system.
