You’ve probably noticed your Ram 1500 sitting at an unusual height or displaying a suspension warning light. Don’t worry – the air suspension system might just need a reset. This sophisticated system that gives your truck its smooth ride and adaptive height capabilities can sometimes get confused, but a proper reset can often fix things without an expensive trip to the dealer.
What Is the Ram 1500 Air Suspension System?
The Ram 1500’s air suspension isn’t just fancy tech – it transforms how your truck handles different situations. Unlike traditional spring suspensions, this system uses air-filled springs that can be adjusted on the fly.
The system consists of several key components:
- Air springs (replacing conventional coil or leaf springs)
- A compressor that fills these springs with pressurized air
- Height sensors monitoring the truck’s position
- An electronic control module managing the whole system
This setup gives you real advantages on the road. Your truck rides smoother over bumps, maintains level height even when loaded with heavy cargo, and provides better stability and handling. You can even adjust the ride height for different situations – lower for highway efficiency or raise it for off-road adventures.
The downside? More complexity means more potential trouble spots, especially with components made from thermoplastic materials like cylinders and pistons that might not hold up as well as metal parts in traditional suspensions.
Three Ways to Reset Your Ram 1500 Air Suspension
Method 1: Using the Suspension Buttons
This is the quickest and easiest reset approach:
- Park on level ground (this is crucial)
- Turn the ignition to “ON” but don’t start the engine
- Find the suspension buttons on your center console (they show a truck icon with up/down arrows)
- Press and hold both up and down buttons simultaneously for about 40 seconds
- Wait for the confirmation chime
- Release the buttons and let the system recalibrate
This simple method often fixes minor glitches and should be your first attempt when troubleshooting.
Method 2: Using the Infotainment Display
If your truck has the Uconnect infotainment system, try this software-based approach:
- Park on level ground with the ignition in “ON” position
- Navigate to the Settings menu on your touchscreen
- Find and open the Suspension Settings section
- Select either “Transport Mode” or “Wheel Alignment Mode”
- Let the system raise to its normal ride height
- The system will calibrate and reset itself
- Remember to switch back to “Normal Mode” when finished
This method works well for resolving calibration issues through the truck’s software interface.
Method 3: The Battery Disconnect Reset
When the other methods fail, this more drastic approach can work:
- Check the air suspension fuse first to make sure it’s not blown
- Open the hood and locate the battery (right side of engine compartment)
- Using a proper wrench, disconnect the negative terminal first
- Keep the cable away from the terminal to prevent accidental reconnection
- Disconnect the positive terminal next
- Wait at least 30 seconds (a full system reset)
- Reconnect in reverse order: positive terminal first, then negative
Be aware this will reset all electronic systems in your truck – you’ll need to reprogram radio presets, clock settings, and other personalized electronics.
Common Air Suspension Problems and Troubleshooting
The air suspension system can experience several issues beyond those fixed by a simple reset:
Complete System Failure
When your system becomes entirely unresponsive with no lights or auto-leveling, you might be facing controller module or compressor failure. This is one of the most serious and expensive problems, potentially costing around $2,000 at dealership rates.
Cold Weather Performance Issues
Many Ram owners report air suspension problems in freezing temperatures:
- Issues begin appearing around 28°F
- Complete system “freeze up” can occur at -20°F or below
- Temperature-related failures might leave you stranded in winter conditions
Diagnostic Checks
Before diving into expensive repairs:
- Check the air suspension fuse – a blown fuse is an easy and inexpensive fix
- Consider purchasing AlfaOBD software for Android devices to access system information and error codes
- Look for air leaks around springs, lines, and fittings
Maintaining Your Air Suspension System
Regular checks significantly extend the life of your air suspension system:
| Service Interval | Normal Use | Heavy Towing/Hauling |
|---|---|---|
| Inspection Schedule | 7,500-10,000 miles | 5,000-8,000 miles |
| Components to Check | Air springs, lines, fittings, air filter | Same, plus compressor health |
| Warning Signs | Uneven ride height, compressor running excessively | Same, plus suspension warning lights |
During routine service:
- Check air pressure levels in all springs
- Inspect for leaks in the system
- Replace the air filter when necessary
- Clean sensors if they’re covered in road debris
How you drive matters too. Avoid deep water crossings or large obstacles that might damage components. Distribute cargo weight evenly to prevent undue stress on the system.
Alternative Solutions for Persistent Problems
If you’re facing ongoing air suspension issues, especially in extremely cold climates, you might consider alternative solutions.
Converting to Traditional Suspension
Some owners replace their troublesome air suspension with conventional components:
- Conversion kits using Bilstein shocks and salvage yard springs cost approximately $600
- Many owners report improved reliability after conversion
- Some even prefer the ride quality of the traditional setup
This conversion involves removing all air suspension components and installing conventional shocks and springs. Mechanically inclined owners sometimes perform this work themselves, though professional installation is recommended.
Warranty Considerations
Before converting your suspension:
- Check if your truck is still under warranty
- Understand that conversion will likely void suspension-related warranty coverage
- Weigh the cost of potential warranty repairs against conversion costs
Cold Weather Workarounds
If your system fails during extremely cold weather:
- Check the air suspension fuse once temperatures normalize
- Consider disconnecting the battery overnight and reconnecting in warmer conditions
- Some owners use engine block heaters or park in garages to maintain system functionality
Practical Tips for Daily Driving with Air Suspension
When your Ram 1500’s air suspension is working properly, these tips help maintain its performance:
- Allow the system to fully adjust before driving off after startup
- Use the “Entry/Exit” mode when parked to make getting in and out easier
- Switch to “Aero” mode on highways for better fuel economy
- Raise to “Off-Road” height only when necessary and reduce speed while elevated
- Return to normal ride height before highway driving
- Listen for unusual compressor sounds that might indicate problems
The suspension control buttons let you manually adjust between these height settings:
- Entry/Exit: Lowest setting for easy access (not for driving)
- Aero: Slightly lowered for better aerodynamics at highway speeds
- Normal: Standard driving height
- Off-Road 1: Moderate lift for light off-road use
- Off-Road 2: Maximum height for serious obstacles (speed limited)
Real-World Owner Experiences
Many Ram 1500 owners share mixed experiences with the air suspension system:
“After three years of trouble-free operation, my system suddenly stopped working in January when temperatures dropped below zero. A simple fuse replacement fixed it completely.”
“I loved the air suspension until it failed at 67,000 miles. The $2,400 repair bill convinced me to convert to traditional springs and shocks. Now I have no worries about it failing again.”
“The trick to keeping the air suspension working is regular maintenance. I’ve gone 120,000 miles with only minor issues by having it checked at every oil change.”
“Mine would randomly drop overnight. After three reset attempts using the button method, it’s been perfect for months. Don’t give up on the simple fixes first.”
Making the Most of Your Ram’s Air Suspension
