Ram 1500 Auto Start Stop Disable: Full Guide 2019-2026
The Ram 1500 auto start stop disable process is simple if you only want the system off for the current drive. Press the factory Stop/Start OFF switch, and the truck disables Autostop until the next ignition cycle.
Ram does not provide a normal factory setting that keeps Stop/Start switched off after every restart on the 2019 through 2026 trucks covered here. The 2024, 2025, and 2026 Ram documentation all state that the system returns to ON after the ignition is cycled.
If pressing the button every drive is the problem, a plug-and-play preference-memory module is the least invasive automatic option. The important part is matching the module to your exact model year because 2019 through 2024 and 2025 through 2026 trucks use different aftermarket installations.
What Determines Your Ram 1500 Disable Method
Three things determine which Ram 1500 start stop disable method makes sense: model year, factory system configuration, and the result you want.
Recommended Best Deal Products
The first split should always be 2019 through 2024 versus 2025 through 2026. Current module manufacturers use separate products for these two groups and specifically warn against installing the older device in a 2025 truck.
Check Your Model Year
For 2019 through 2024 Ram 1500 DT trucks, available preference-memory modules commonly connect at the vehicle’s gateway wiring below the steering column.
For 2025 and 2026 Ram 1500 trucks, use only a device specifically listed for those model years. Current 2025 through 2026 products use a different installation location and electrical connection.
Check Your Factory System
On the 2024 Ram 1500, Ram describes Stop/Start as part of eTorque-equipped configurations. The system uses the motor-generator and hybrid electrical system to restart the engine after an Autostop.
The 2026 owner’s manual documents both 48-volt eTorque Stop/Start and 12-volt Stop/Start configurations. Ram specifically states that 12-volt Stop/Start trucks use a main and supplemental battery.

Decide What You Actually Want
There are three different goals owners often describe as “permanent disable.”
- Disable it for one drive: Press the factory Stop/Start OFF switch.
- Automatically retain OFF after restart: Install a compatible preference-memory module.
- Physically or electronically alter the factory system: Battery, sensor, wiring, or programming modifications require much more caution.
For most owners searching this keyword, the second option is what they actually want.
How to Disable Ram 1500 Auto Start Stop
If you only want Auto Start/Stop disabled for the current trip, no tools or modifications are required.
Ram’s official procedure is essentially the same across the verified 2024, 2025, and 2026 documentation.
Find the Stop Start OFF Switch
Look at the center switch bank near the rotary transmission selector on applicable Ram 1500 configurations.
The button carries the circular-arrow “A” Stop/Start symbol with OFF beneath or beside it. Ram’s own illustrations show the control adjacent to the transmission and four-wheel-drive controls.

Press the OFF Switch
With the truck running:
- Press the Stop/Start OFF switch.
- Confirm the indicator light on the switch illuminates.
- Check the instrument cluster.
- The cluster should display STOP/START OFF.
- Autostop is now disabled for that ignition cycle.
Ram confirms this exact switch-light and cluster-message behavior in its 2024 and 2025 documentation. (Mopar Vehicle Information)
You can drive normally after disabling it. The engine should not enter an Autostop specifically because of the Stop/Start function while the system remains switched off.
Restart the Ram 1500
This is where the factory method becomes inconvenient.
Ram states that Stop/Start resets to ON every time the ignition is turned OFF and back ON. That behavior is explicitly documented for 2024, 2025, and 2026.
So the factory button is a temporary disable, not a stored permanent setting.
How 2019 to 2024 Ram 1500 Memory Modules Work
For a compatible 2019 through 2024 Ram 1500, a preference-memory module is the cleanest option when you want the truck to retain your previous ESS selection.
These devices do not need to remove the factory Stop/Start system. Instead, they restore the previous button preference automatically when you start the truck.
Use the Gateway Module Connection
Two current manufacturers describe the 2019 through 2024 solution as an inline gateway connection.
Autostop Eliminator lists its device as compatible with 2019 through 2024 Ram 1500 models, including eTorque, and says it installs into the gateway module.
4D Tech gives more detail. Its current device plugs inline with the factory harness at the 12-pin gateway connector below the steering wheel.
The basic installation sequence is:
- Park the truck and switch the ignition off.
- Access the gateway-module area beneath the steering column.
- Locate the correct 12-pin factory connector.
- Disconnect that connector.
- Connect the module inline between the factory harness and gateway.
- Secure the wiring so it cannot interfere with pedals or steering components.
- Start the truck.
- Test the factory Stop/Start button.
- Switch Stop/Start OFF.
- Restart the truck and verify the preference is retained.
Always follow the instructions supplied with the exact device you buy because connector access and harness design can differ between manufacturers.
Check 2021 Trucks Before Ordering
4D Tech publishes an unusual compatibility warning specifically for some 2021 Ram 1500s.
If pressing your factory Start/Stop button does not make the OFF indicator respond normally, 4D Tech says its device will not work with that configuration. (4D Tech)

Know What Permanent Means
A memory module is often marketed as a “permanent disable,” but that wording can be misleading.
The device is generally remembering your preferred factory switch state. You can still press the factory button and turn Stop/Start back on when desired. Both major products researched for this guide retain the factory button’s operation.
As of August 2026, the researched 2019 through 2024 Autostop Eliminator is listed at $99.99. Prices can change after publication.
How 2025 to 2026 Ram 1500 Start Stop Differs
Do not buy a 2019 through 2024 module for a 2025 or 2026 Ram 1500.
Current manufacturers separate the newer trucks into their own product group. 4D Tech explicitly says its 2019 through 2024 device will not work on a 2025 Ram pickup. (4D Tech)
Use the 2025 to 2026 Specific Module
Autostop Eliminator currently lists a dedicated device for the 2025 and 2026 Ram 1500.
The manufacturer states that the device:
- works with its listed Ram 1500 engine configurations, including RHO
- retains factory ESS button operation
- uses a plug-and-play connection
- installs in the passenger footwell area
- automatically restores the driver’s previous Start/Stop preference
That passenger-footwell installation is a major reason not to follow older gateway-module tutorials blindly.
Follow the Newer Installation Procedure
The manufacturer lists a 10 mm deep socket or wrench, flat screwdriver, and cutting snips for its current 2025 through 2026 installation.
It also estimates the installation at under five minutes for its own product. Treat that time as a manufacturer estimate, not a guaranteed DIY time.
The safe workflow is:
- Verify the product specifically lists your 2025 or 2026 Ram 1500.
- Shut the truck off.
- Follow the manufacturer’s passenger-footwell access instructions.
- Disconnect only the connector identified in those instructions.
- Install the module inline.
- Secure the harness exactly as instructed.
- Reassemble the trim.
- Start the truck.
- Verify the factory ESS button still operates.
- Test whether your last OFF preference returns after another ignition cycle.
Which Permanent Disable Methods Carry More Risk
A method that prevents Start/Stop from working is not automatically a good permanent-disable solution.
Battery, sensor, fuse, and wiring changes can affect systems beyond ESS. This matters even more on newer trucks with more complicated battery-management architecture.
Auxiliary Battery Removal
Some owners of 2025 Hurricane-powered Ram 1500s have experimented with removing the supplemental battery.
One documented 2025 Ram 1500 Standard Output owner reported removing the auxiliary battery and disabling Start/Stop without diagnostic trouble codes during that owner’s testing. The owner used an AutoAuth-capable scan tool to check modules afterward. (5th Gen Rams)
That is one owner-reported modification, not an official Ram procedure.
The 2026 Ram owner’s manual also warns that 12-volt Stop/Start configurations have two batteries and that both must be disconnected to completely de-energize the 12-volt electrical system. Ram directs owners to an authorized dealer for the proper disconnect process.
That factory warning is enough reason not to recommend auxiliary-battery removal as the first solution.
If battery cost is part of your decision, our Ram eTorque battery replacement cost guide covers the broader battery-service topic.
Battery Sensor Disconnects
Do not unplug a battery monitoring sensor simply because doing so may prevent Start/Stop from becoming ready.
The Stop/Start controller considers battery charging state and 12-volt electrical demand when deciding whether Autostop is available. Ram lists battery charging and excessive 12-volt loads among conditions that can inhibit Autostop on the 2024 system.
Forcing a system unavailable by creating an electrical abnormality is different from properly disabling the feature.
Fuse Removal
There is no verified factory procedure in the researched Ram documentation that says to pull a fuse to permanently disable Start/Stop.
A fuse can feed more than the single behavior you are trying to change. Do not use a fuse-pull method unless the exact circuit and consequences have been confirmed from factory service information for your model year.
Wire Cutting
Cutting factory wiring is unnecessary when the factory OFF switch and reversible inline modules already exist.
Permanent wiring changes also make later troubleshooting harder. They can create a second problem when a technician tries to diagnose an unrelated electrical complaint.
AlfaOBD Coding
We did not find a verified, repeatable AlfaOBD setting that permanently disables ESS across 2019 through 2026 Ram 1500 DT trucks.
Ram owner discussions involving 2021 and 2022 DT trucks specifically report that the desired Start/Stop configuration was not available through AlfaOBD. That is community evidence rather than official AlfaOBD documentation, so we would not publish an unverified coding path as a working solution. (5th Gen Rams)
If your truck already has Start/Stop faults instead of normal operation, diagnose those faults rather than trying random configuration changes. Our Ram eTorque problems guide covers related electrical and Stop/Start symptoms.
Factory Button vs Memory Module vs Electrical Modification
The best method depends on whether you want convenience or an actual modification to the truck.
| Method | Best For | Works After Restart | Modification Level | Reversible | Our Recommendation |
|---|---|---|---|---|---|
| Factory OFF button | Occasional ESS disable | No | None | Yes | Safest factory method |
| Preference-memory module | Owners who want OFF retained | Yes, restores preference | Low | Usually yes | Best for most owners |
| Coding changes | Advanced configuration work | Not reliably verified | Moderate | Depends | Do not use without verified procedure |
| Battery modification | Electrical diagnosis or custom work | Can disable ESS | High | Depends | Not first choice |
| Fuse or wiring modification | Specialized electrical work | Depends | High | Often harder | Avoid for routine ESS disable |
For most 2019 through 2026 Ram 1500 owners, there is little reason to disturb the battery system or factory wiring just to stop pressing one button.
A compatible preference-memory module achieves the desired behavior while retaining the original control.
Which Ram 1500 Disable Method Should You Choose
If you only dislike Start/Stop occasionally, press the factory OFF button. It costs nothing and changes no hardware.
If you own a compatible 2019 through 2024 Ram 1500 and want OFF remembered, use a verified module made specifically for 2019 through 2024 DT trucks.
If you own a 2025 or 2026 Ram 1500, use a device explicitly designed for the newer electrical architecture. Do not reuse instructions or modules marketed only for 2019 through 2024.
If you want to modify batteries, sensors, wiring, or vehicle coding, treat that as an electrical modification rather than a simple Start/Stop disable. Verify the complete procedure for your VIN and configuration first.
The least invasive method that gives you the behavior you want is usually the correct one.
Why Ram 1500 Start Stop May Not Activate
An enabled Stop/Start system does not shut the engine off every time you stop.
The official 2024 Ram 1500 manual lists several conditions that can keep Autostop from activating. (Mopar Vehicle Information)
| Condition | What You May Notice | What to Check |
|---|---|---|
| Driver seat belt unbuckled | Autostop stays unavailable | Buckle driver’s belt |
| Driver door open | Engine remains running | Close driver’s door |
| Steep grade | Autostop may be inhibited | Normal system behavior |
| Cabin temperature demand | Engine stays running | HVAC demand may be high |
| Full defrost at high blower | Autostop unavailable | Defrost operation |
| Engine not at operating temperature | ESS remains not ready | Allow engine to warm |
| High engine or exhaust temperature | Engine continues running | Normal protection strategy |
| Battery charging | Autostop may be unavailable | Check battery condition if persistent |
| Transmission not in Drive | No Autostop | Select Drive when appropriate |
| Hood open | System inhibited | Close hood |
| 4WD LOW selected | Autostop unavailable | Normal system behavior |
| Tow Haul selected | Autostop unavailable | Normal system behavior |
| Accelerator input | Engine continues running | Release accelerator at stop |
| Heavy 12-volt load | Autostop may be inhibited | Reduce electrical demand if practical |
Ram also says the system can go several consecutive drives under extreme conditions without meeting every criterion required for Autostop.
So an engine that stays running at one traffic light does not automatically mean Start/Stop has been permanently disabled.
If the cluster displays SERVICE STOP/START SYSTEM, that is different. Ram identifies that message as a system malfunction requiring diagnosis.
Best Way to Disable Ram 1500 Auto Start Stop
For most owners, the best Ram 1500 auto start stop disable method is either the factory OFF button or a year-compatible preference-memory module.
Use the button if you want zero modifications. Choose a reversible memory module if you want the truck to restore your OFF preference automatically.
The critical fitment break is 2019 through 2024 versus 2025 through 2026. Do not install an older gateway-style product on a newer Ram unless that exact device manufacturer specifically lists your year.
Battery removal, sensor disconnects, fuse tricks, and unsupported coding changes add unnecessary variables when a reversible solution already exists.
Ram 1500 Auto Start Stop Disable FAQs
Does the Ram 1500 Have a Permanent Auto Start Stop Off Setting?
Not through the normal factory controls covered in the researched manuals. Ram states that the Stop/Start system resets to ON after the ignition is switched off and back on. A preference-memory module can automatically restore OFF without removing the factory function.
Does Pressing the ESS Button Permanently Disable Start Stop?
No. Pressing the factory Stop/Start OFF button disables Autostop for that ignition cycle. After you turn the ignition off and restart the Ram 1500, the factory system returns to ON.
Can I Disable Start Stop on a Ram 1500 eTorque?
Yes. You can use the factory Stop/Start OFF switch on equipped trucks. Current 2019 through 2024 aftermarket memory modules also specifically list compatibility with eTorque-equipped Ram 1500 models.
Is the 2025 Ram 1500 Start Stop System Different?
The factory OFF-button behavior remains similar, but aftermarket installation is different. Current manufacturers require a separate 2025 through 2026 device rather than the gateway module sold for 2019 through 2024 trucks.
Will a Start Stop Eliminator Disable the Factory Button?
Not with the two researched plug-and-play products. Both manufacturers state that their modules retain the factory Start/Stop button, allowing you to change the ESS preference later. Verify this feature on any other product before buying.
Does a Start Stop Eliminator Affect Remote Start?
The researched 4D Tech 2019 through 2024 module specifically states that remote start remains functional. Do not assume the same for every aftermarket module because wiring and control strategies can differ between products.
Can I Remove the Auxiliary Battery to Disable Start Stop?
Some owners have reported doing this on newer Ram 1500s, but Ram does not present auxiliary-battery removal as the normal ESS disable method. The 2026 manual warns that two-battery Stop/Start configurations require both batteries to be disconnected to fully de-energize the 12-volt system.
Why Does My Ram Say Start Stop Not Ready?
The system may be waiting for normal operating conditions. Battery charging, HVAC demand, engine temperature, Tow Haul mode, 4WD LOW, an open hood, and several other conditions can prevent Autostop even though ESS remains enabled.
