Electronic Bypass Module (EBM) Installation
The Arnott exclusive Electronic Bypass Module (U.S. Pat. No. 9,329,917) is a critical component designed to eliminate suspension dashboard warning lights that would otherwise appear after converting from air suspension. It includes complete step-by-step instructions and wiring information to make installation quick and easy. The EBM turns off suspension dashboard warning lights and is a patented design.

Operation
After successful installation, your vehicle's suspension will operate with traditional coil springs, providing a consistent ride height and handling characteristics similar to a standard coil spring equipped vehicle. The conversion kit is designed to restore the vehicle's ride and handling to factory specifications, ensuring a comfortable and stable driving experience.

- Check shock absorbers for leaks or damage.
- Ensure all mounting bolts are properly torqued during routine vehicle service.
Troubleshooting
Most issues after installing the conversion kit are related to the electronic bypass module or incorrect installation.
Dashboard Warning Lights
If suspension-related warning lights appear on the dashboard after installation, verify the following:
