Ram 1500 Air Suspension Reset: What Actually Works
There is no universal factory “reset button” for the Ram 1500 air suspension. In many cases, returning the system to normal operation means disabling Tire/Jack Mode, Transport Mode, Wheel Alignment Mode, or Service Mode, selecting Normal Ride Height, and driving the truck briefly—only if it is safe to do so.
If the truck remains low, leans to one side, displays a persistent “Service Air Suspension” warning, or cannot build pressure, a reset will not repair the underlying fault. The system may have an air leak, weak battery, blown fuse, damaged height sensor, faulty compressor, valve-block problem, or stored diagnostic code.
Quick answer: Start the engine on level ground, close all doors, turn off any special suspension mode, select Normal Ride Height, and allow the truck time to level itself. If the suspension is not collapsed and the tires have safe clearance, a short drive may automatically cancel certain modes. Stop if the truck does not rise or feels unsafe.
Before You Try to Reset the Air Suspension
Complete these checks before changing any suspension setting:
- Park the truck on firm, level ground.
- Confirm that no tire is rubbing against the body or wheel well.
- Remove unusually heavy or unevenly distributed cargo.
- Make sure the battery is sufficiently charged.
- Close the doors before requesting a height change.
- Do not work beneath a truck supported only by its air suspension or a jack.
Do not drive the truck if one corner is severely collapsed, a tire is rubbing, steering feels unstable, or the instrument cluster instructs you to stop. These conditions require inspection rather than another reset attempt.
How to Reset Ram 1500 Air Suspension Safely
The following procedure does not erase diagnostic trouble codes or recalibrate replacement components. It returns the driver-accessible suspension settings to normal and may resolve a system that was accidentally left in a service-related mode.
1. Start the Engine
Start the engine while the truck is parked on level ground. RAM manuals state that modes such as Tire/Jack Mode, Transport Mode, and Wheel Alignment Mode are intended to be enabled with the engine running.
Allow the engine to run while the system checks vehicle height and air pressure. Close all doors because an open door may delay or prevent a requested height change on some model years.
2. Check for an Active Suspension Mode
Open the suspension settings in the instrument-cluster menu or Uconnect screen. The exact menu name depends on the model year and installed radio.
- Tire/Jack Mode: disables automatic leveling while changing a tire or lifting the truck.
- Transport Mode: lowers the truck and disables automatic leveling for flatbed transportation.
- Wheel Alignment Mode: prevents automatic leveling during an alignment.
- Service Mode: appears in certain newer model-year instructions and disables automatic suspension movement during service.
Turn off any mode that should not be active. Do not confuse these settings with Aero Mode or Entry/Exit Mode, which are normal ride-height functions.
3. Select Normal Ride Height
Use the suspension height control to request Normal Ride Height. Watch the indicator lights or instrument-cluster message while the truck adjusts.
The compressor may run briefly. The truck should rise or lower evenly and then stop at the selected height. Repeated compressor operation, an unusually long running time, or no height change points to a fault rather than a setting that simply needs resetting.
4. Perform a Normal Ignition Cycle
If the suspension does not respond, switch the truck off normally and allow its electronic systems to power down. Restart the engine, close the doors, and request Normal Ride Height again.
This may clear a temporary communication or mode-selection issue. It will not fix a pneumatic leak, failed compressor, damaged sensor, wiring fault, or mechanical obstruction.
5. Drive the Truck Briefly—Only If Safe
Official RAM documentation states that driving disables Tire/Jack Mode, Transport Mode, and Wheel Alignment Mode on applicable models. The 2020 RAM 1500 manual also notes that Tire/Jack Mode is canceled when the vehicle is driven above 5 mph.
Take a short, low-speed drive only when the truck has adequate tire clearance, sits reasonably level, and displays no stop-driving warning. Return to a safe parking area and confirm that Normal Ride Height is available.
Does Holding Both Suspension Buttons for 40 Seconds Work?
A widely repeated procedure tells owners to turn the ignition on and hold the suspension up and down buttons simultaneously for approximately 30–40 seconds until a chime sounds.
However, this is not documented as a universal owner reset procedure in the RAM manuals reviewed for this guide. Button layout, suspension controls, software, and available modes differ between generations. A chime may indicate a control input or mode response, but it does not prove that the suspension has completed a factory calibration.
Do not rely on this method to erase a warning or repair a truck that is sagging. Start with the documented suspension modes and the owner’s manual for your exact model year. A persistent fault requires suspension-module diagnostics.
Reset Differences by Ram 1500 Model Year
| Model years | Generation | What to check |
|---|---|---|
| 2013–2018 | DS | Check the instrument-cluster or Uconnect suspension settings for Tire/Jack, Transport, or Wheel Alignment Mode. Controls and menu availability vary by radio and trim. |
| 2019–2024 | DT | Use the Uconnect or cluster Suspension menu, turn off special modes, select Normal Ride Height, and verify the selected height using the console indicators. |
| 2025 and newer | DT | Check the current owner’s handbook for Tire/Jack Mode or Service Mode terminology. Menu wording and available features can change with software and equipment. |
Not every Ram 1500 has four-corner air suspension. Before following any procedure, confirm that the truck is factory-equipped with the system and use the manual matching its exact year, configuration, and Uconnect version.
Why the Ram Air Suspension May Not Reset
| Symptom | Possible cause | Recommended next step |
|---|---|---|
| One corner drops while parked | Air spring, fitting, line, or valve-block leak | Measure ride height and perform a proper leak test. |
| Truck will not rise and compressor is silent | Fuse, relay, wiring, low voltage, module, or compressor fault | Check battery voltage and scan the suspension module. |
| Compressor runs repeatedly | Air leak or weak compressor | Find the leak before replacing or overworking the compressor. |
| Suspension works after warming up | Moisture, freezing, weak compressor, valve issue, or marginal electrical connection | Diagnose the system under the conditions that cause the fault. |
| Height is incorrect after replacing a sensor or component | Calibration or installation issue | Use a compatible scan tool and the correct service procedure. |
| “Service Air Suspension” returns immediately | Active or stored system fault | Read the Air Suspension Control Module codes before clearing anything. |
For a detailed breakdown of these failures, see our guide to Ram 1500 air suspension problems. If the compressor is the main concern, follow our separate air suspension compressor testing guide.
Should You Disconnect the Battery?
Disconnecting the battery is commonly suggested online, but it should not be the first diagnostic step. It may reset unrelated vehicle settings, erase useful evidence, and temporarily hide a warning without repairing the cause.
If battery disconnection is required by a manufacturer repair procedure, follow the instructions for your exact model year. Otherwise, read the suspension-module fault codes before removing power so the original problem is not lost.
When a Scan Tool Is Required
A basic code reader that only accesses engine faults may not communicate with the Air Suspension Control Module. A compatible bidirectional scan tool may be needed to:
- Read manufacturer-specific suspension codes.
- View live ride-height sensor data.
- Command the compressor or valves during diagnosis.
- Perform a ride-height calibration after certain repairs.
- Confirm whether the module sees Tire/Jack, Transport, Alignment, or Service Mode as active.
Calibration should not be used to compensate for a leaking air spring, bent sensor linkage, incorrect installation, or damaged suspension component. Repair the physical problem first.
Frequently Asked Questions
Where is the Ram 1500 air suspension reset button?
The Ram 1500 does not have a dedicated universal air-suspension reset button. The console buttons select ride height, while special modes are controlled through the instrument cluster or Uconnect settings on applicable models.
How do I clear “Service Air Suspension” on a Ram 1500?
First verify that no service-related suspension mode remains active and perform a normal ignition cycle. If the warning returns, scan the Air Suspension Control Module. Clearing the message without correcting its fault will usually make it return.
Why is my Ram 1500 stuck in Entry/Exit Mode?
The system may be waiting for the required operating conditions, experiencing low voltage, detecting an open door, or storing a suspension fault. Start the engine, close the doors, request Normal Ride Height, and check for warning messages. Do not drive if tire clearance is inadequate.
Will a reset fix a leaking Ram air suspension?
No. A reset cannot seal a leaking air spring, line, fitting, reservoir, or valve block. Continued resetting may allow the compressor to run excessively and create an additional failure. Use our air suspension leak repair guide to understand the correct diagnostic process.
Do 2017 and 2019 Ram 1500 trucks use the same reset procedure?
Not necessarily. The 2017 truck belongs to the DS generation, while the redesigned 2019 model may be a DT or a continued-production Classic DS. Menus, controls, and module procedures can differ. Identify the generation and consult the matching owner’s manual before changing settings.
Use the Documented Modes Before Replacing Parts
A Ram 1500 air suspension reset should begin by returning the system to its documented normal operating mode—not by disconnecting the battery or repeatedly holding buttons. Start the engine, close the doors, disable Tire/Jack, Transport, Wheel Alignment, or Service Mode when active, and request Normal Ride Height.
If the truck still will not level itself, stop treating the problem as a reset issue. Record the symptoms, read the suspension-module codes, test for leaks, and diagnose the electrical and pneumatic system before replacing components.
