1. Disconnect and reconnect the battery/ECM hard reset technique

This technique is relatively easier. All you need to do is disconnect your battery, wait for a while, and reconnect it. It will effectively reset the check engine light on your Dodge Ram 1500.

Start by opening the hood of your truck and locating the battery. Once you’ve found it, disconnect the negative terminal first and then the positive terminal.

Wait for at least 30 seconds before connecting the terminals to their original position. Make sure you connect the positive terminal first and then the negative terminal.

Close the hood of your truck and start the engine to see if the check engine light has reset.

If the light is still on, move on to the next technique below.

2. Turning the ignition on and off

This method is also quite simple. All you need to do is turn your truck’s ignition on and off 3 times in a row.

Start by turning the key to the ON position for about 5 seconds without starting the engine. Then, turn the key OFF and wait for at least 10 seconds before turning it back ON.

Repeat this process 3 times, and then start your truck’s engine. Hopefully, this will fix the engine light; otherwise, move to the next method.

3. Use an OBD-II scanner/reader.

This technique requires an OBD-II scanner or reader, which you can easily purchase from any auto parts store.

An OBD-II scanner allows you to read and clear the diagnostic trouble codes (DTCs) from your truck’s computer. By doing this, you can easily reset the check engine light on your Dodge Ram 1500.

Connect the OBD-II scanner to your truck and turn it on. Once connected, you should see the DTCs displayed on the screen.

Clear the codes and turn OFF the scanner. Start your truck’s engine, and the engine light must go off.

If you don’t have an OBD-II scanner, you can take it to any auto parts store or mechanic, and they can reset the check engine light for you. Or get your personal one from one of the best tuners/programmers for Hemi 5.7 RAM 1500 trucks here.
