If you own a truck equipped with a 6.7 Cummins engine, you may have noticed the “Perform Service” message appear on your dashboard. This indicator is part of the truck’s onboard monitoring system, reminding you that scheduled maintenance — such as an oil change or fuel filter replacement — is due. However, after completing the maintenance, the light doesn’t automatically reset. Here’s how to manually reset the Perform Service light on a 6.7 Cummins engine.

Step 1: Turn the Ignition Key

Insert your key into the ignition and turn it to the “On” position, but don’t start the engine. This will activate the dashboard lights and electronic systems.

Step 2: Access the Menu

On most Ram trucks with the 6.7 Cummins diesel, you can use the steering wheel control buttons to navigate through the information display. Use the arrow buttons to scroll until you find the “Vehicle Info” or “Service” screen.

Step 3: Select “Reset Perform Service”

Once you’re on the Perform Service reminder screen, press and hold the “OK” button (or the right arrow button) for a few seconds. You should see a confirmation message, such as “Perform Service Reset” or “Reset Complete.”

Step 4: Turn the Ignition Off and On Again

Turn the ignition off, then start the truck to verify that the message has cleared. If the Perform Service light no longer appears, the reset was successful.

Alternative Method (If the Above Doesn’t Work)

Some older models or trims may require a slightly different approach:

1. Turn the ignition to “On.”

2. Press the accelerator pedal three times within 10 seconds.

3. Turn the ignition off.

4. Start the engine to confirm that the light has reset.

Why the “Perform Service” Light Appears

The Perform Service indicator is designed to help maintain optimal engine performance and fuel efficiency. Common triggers include:

• Crankcase filter replacement intervals

• Oil or fuel filter service reminders

• EGR or emissions system maintenance alerts

Neglecting these reminders can affect the reliability and longevity of your 6.7 Cummins engine.
