Dodge Ram Eco Mode Turn off Permanently

If you’re the owner of a Dodge Ram truck, you may be wondering what the Eco mode is and how to turn it off permanently. The Eco mode is a fuel-saving feature that automatically kicks in when your truck is idling for more than 10 seconds. It shuts off the engine to save fuel, and then restarts it when you step on the gas pedal.

While this can be a great feature if you’re simply sitting in traffic or parked, some owners find it annoying and prefer to keep their engine running at all times. If you fall into this camp, don’t worry – there’s an easy way to disable the Eco mode permanently. Simply press and hold the button on your dash that says “ECO” for about 5 seconds.

A message will appear letting you know that the Eco mode has been turned off permanently. Now your truck will stay in “run” mode no matter how long it’s idling, so you don’t have to worry about it shutting down on you unexpectedly.

Disabling MDS can be beneficial if you’re looking for more power and performance from your truck. Here’s how to do it: 1. Start by disconnecting the negative battery terminal.

This will prevent any electrical shorts while working on the vehicle. 2. Next, locate the MDS solenoid located on the driver’s side of the engine block near the oil filter housing. There will be two wires connected to it – one black and one green.

3. Using a wire cutter, cut the green wire and tape off the end so it doesn’t touch anything else. Then reconnect the negative battery terminal. 4. Finally, start up your truck and test it out!

You should notice an increase in power and performance without MDS getting in the way.

Does Tow Mode Disable Mds?

MDS, or Multi-Displacement System, is a fuel-saving technology found in certain Chrysler vehicles with Hemi engines. When activated, it allows the engine to run on four cylinders during light-load driving conditions. This can improve fuel economy by up to 20 percent.

While MDS is active, the engine will automatically switch back to eight cylinders when more power is needed. This happens seamlessly and without any input from the driver. However, some drivers may want to disable MDS altogether.

There are a few different ways to do this. One way is to simply select the “Tow Mode” setting on the vehicle’s dash control panel. This will disable MDS and keep the engine running on all eight cylinders at all times.

Another way to disable MDS is by disconnecting the battery for 30 seconds or more. This will reset the system and prevent it from activating again until the battery is reconnected. Lastly, some aftermarket tuners offer programs that can disable MDS permanently.
