The Ram 1500 comes with a feature called Mds. This stands for Multi-Displacement System and it allows the engine to run on four cylinders when full power is not needed. This can save fuel, but it can also cause the engine to run rough when accelerating from a stop.
If you want to disable this feature, there are a few things you need to do.
First, you need to find the fuse box. It is usually located under the hood, but if you can’t find it there, consult your owner’s manual.
Once you have found the fuse box, look for a fuse labeled “MDS.” Remove this fuse and replace it with one that has the same amperage rating.
Next, you need to disconnect the battery.
This will prevent any electrical issues while you’re working on the vehicle. Once the battery is disconnected, locate the Mds solenoid and unplug it from its electrical connector. You can now reattach the battery and start your vehicle.
The Mds system should now be disabled.
- Open the hood of your Ram 1500 and locate the Mds solenoid
- Using a wrench, disconnect the negative battery cable from the terminal on the solenoid
- Remove the two bolts that secure the Mds solenoid to the engine using a wrench
- Pull the Mds solenoid away from the engine and set it aside
- Reconnect the negative battery cable to the terminal on the solenoid and close the hood of your Ram 1500
Ram 1500 Mds Delete
The Ram 1500 is a light duty truck that has been around since 2009. It’s available in both two-wheel and four-wheel drive options. The four-wheel drive option is only available on the Hemi V8 engine.
The Ram 1500 comes standard with a 3.6L V6 engine, but can be upgraded to a 5.7L Hemi V8 or a 3.0L EcoDiesel V6.
One feature of the Ram 1500 that has caused some controversy is the MDS (Multi-Displacement System). The MDS allows the Hemi V8 engine to run on four cylinders when it’s not under heavy load, in order to save fuel.
Some people argue that this system reduces the power of the Hemi engine, and therefore should be deleted when possible.
If you’re interested in deleting the MDS from your Ram 1500, there are a few things you need to know first. First, you’ll need to have a programmer or tuner that can disable the MDS system – this typically isn’t something that can be done through the factory settings.
Second, you may void your warranty by doing this modification, so it’s important to weigh your options carefully before making any decisions. Finally, once the MDS is disabled, you’ll likely see an increase in fuel consumption since the Hemi engine will no longer be able to shut off cylinders when they’re not needed.

How Do You Turn off Mds on a Ram 1500 Hemi?
If you’re looking to turn off MDS on your Ram 1500 Hemi, there are a few things you’ll need to do. First, locate the MDS solenoid on the engine. This should be easy to find as it’s usually labeled.
Once you’ve found it, disconnect the negative battery cable. Next, remove the MDS solenoid bolts using a wrench or socket set. With the bolts removed, pull out the MDS solenoid and discard it.
Finally, reattach the negative battery cable and start up your engine – MDS should now be disabled!
How Do You Turn off the Mds on a 2010 Dodge Ram 1500?

1. Turn the ignition key to the “On” position but do not start the engine.
2. Press and release the gas pedal three times within five seconds.
3. Start the engine. The MDS indicator light on the dash will now be off, indicating that the system is disabled.
Is the 5.7 Hemi Mds a Good Engine?
The 5.7L Hemi MDS engine is a good engine. It has a lot of torque and it’s very quiet. It’s a great engine for towing and it gets good gas mileage.
What Does Mds Do for 5.7 Hemi?
The MDS, or Multi-Displacement System, is a cylinder deactivation system used by Chrysler on some of their V8 engines. The system can deactivate half of the engine’s cylinders when full power is not needed, such as during highway cruising, and reactivate them when additional power is required. This allows the engine to operate more efficiently, improving fuel economy.
While the MDS system can improve fuel economy by up to 20%, it does have some drawbacks. One is that it can cause a slight drop in power when activating or deactivating the cylinders. Additionally, the MDS system adds weight and complexity to the engine, which can potentially lead to reliability issues down the road.

Conclusion
If you’re not a fan of the Multi-Displacement System (MDS) on your Ram 1500, there is a way to disable it. Disabling the MDS will result in better fuel economy and improved performance, especially when towing. Here’s how to do it:
1. Open the hood and disconnect the negative battery cable. This will prevent any electrical shorts while you’re working.
2. Locate the MDS solenoid pack on the driver’s side of the engine compartment, near the firewall.
It will have two electrical connectors and two vacuum lines attached to it.
3. Unplug both electrical connectors from the solenoid pack.
4. Use a pair of pliers to gently pull out the small plastic pins that secure the vacuum lines to the solenoid pack (they just push in).
Once they’re removed, you can pull off the vacuum lines. Make sure you remember which line goes where, as they are different sizes.
5. Reattach the negative battery cable and start up your engine – that’s it!
