AvatarByHarold Trujillo Troubleshooting & How To

Keeping your 2018 RAM 2500 in peak condition is essential for ensuring reliability, safety, and optimal performance on the road. One important aspect of vehicle maintenance is managing service reminders, such as the “Perform Service” notification that appears on your dashboard. Understanding how to reset this alert not only helps you keep track of your truck’s maintenance schedule but also ensures that your RAM’s onboard systems accurately reflect its service status.

Whether you’ve just completed an oil change, replaced filters, or performed other routine maintenance, resetting the service light is a crucial step that many owners overlook. This process can seem daunting at first, especially if you’re unfamiliar with the truck’s onboard controls and diagnostic features. However, with the right guidance, resetting the “Perform Service” message can be straightforward and quick, allowing you to get back on the road with confidence.

In the following sections, we’ll explore the importance of the service reminder system, why it needs to be reset after maintenance, and what general steps are involved in the reset procedure for the 2018 RAM 2500. Whether you’re a seasoned truck owner or a first-time RAM driver, this overview will prepare you to handle your vehicle’s service alerts efficiently and effectively.

Resetting the Perform Service Light Using the Instrument Cluster

To reset the Perform Service light on a 2018 RAM 2500 through the instrument cluster, you need to access the vehicle’s driver information display and navigate the menu options. This method is straightforward and does not require any additional tools or equipment.

Begin by turning the ignition switch to the “ON” position without starting the engine. This powers up the dashboard systems. Use the steering wheel controls—specifically the arrow keys and the “OK” button—to access the “Vehicle Info” menu on the instrument cluster.

Within the “Vehicle Info” menu, scroll down to find the “Perform Service” or “Service Interval” option. Selecting this will display the current status of the service interval and the option to reset it.

To reset the Perform Service light:

  • Press and hold the “OK” button until the display changes or begins to flash.
  • Release the button when the reset confirmation appears.
  • Turn the ignition off and then start the engine to verify the reset was successful. The Perform Service light should no longer be illuminated.

If the light remains on after following these steps, repeat the process carefully. In some cases, the system may require a longer hold time on the “OK” button or a vehicle speed reset through driving.

Using an OBD-II Scanner to Reset the Perform Service Light

For a more technical approach, an OBD-II scanner can be used to reset the Perform Service light. This method is recommended if the instrument cluster reset does not work or if the vehicle’s service system requires a more comprehensive reset.

An OBD-II scanner capable of accessing manufacturer-specific codes and service functions is necessary. Many professional-grade scanners or advanced consumer models support RAM and FCA vehicles’ service resets.

The process involves the following steps:

  • Connect the OBD-II scanner to the vehicle’s diagnostic port, located under the dashboard near the driver’s side.
  • Turn the ignition to the “ON” position without starting the engine.
  • Power on the scanner and allow it to communicate with the vehicle’s computer.
  • Navigate to the “Service” or “Maintenance” section in the scanner menu.
  • Select “Reset Perform Service” or the equivalent option.
  • Confirm the reset command and wait for the scanner to complete the process.
  • Turn off the ignition, disconnect the scanner, and start the engine to check if the Perform Service light has reset.

This method can also clear any stored trouble codes related to the service system, ensuring the vehicle’s maintenance schedule is accurately updated.

Perform Service Reset Troubleshooting Tips

Sometimes, the Perform Service light may not reset as expected due to various factors. Consider these troubleshooting tips if you encounter difficulties:

  • Verify the ignition is in the correct position (ON, but engine off) before starting the reset procedure.
  • Ensure the battery voltage is adequate; low voltage can interfere with system communication.
  • If using an OBD-II scanner, confirm it supports FCA vehicles and the 2018 RAM 2500 specifically.
  • Check for active diagnostic trouble codes (DTCs) that may prevent the reset. Clear these codes first.
  • Perform a complete cycle by turning the ignition off, waiting a few minutes, and then repeating the reset steps.
  • Consult the vehicle’s owner’s manual for any model-specific variations or additional instructions.

Maintenance Schedule and Perform Service Intervals

Understanding the maintenance schedule is critical to knowing when the Perform Service light will illuminate. The Perform Service indicator is designed to remind drivers of scheduled maintenance tasks such as oil changes, fluid checks, and inspections.

The following table outlines typical service intervals and the corresponding maintenance actions for the 2018 RAM 2500:

Odometer Reading (Miles) Maintenance Tasks Notes
Every 6,000 miles
  • Engine oil and filter change
  • Check fluid levels (coolant, brake, transmission)
  • Inspect tires and brakes
 Normal driving conditions
Every 12,000 miles
  • Replace engine air filter
  • Inspect suspension and steering components
  • Check battery condition
 Includes all 6,000-mile services
Every 24,000 miles
  • Replace fuel filter
  • Inspect exhaust system
  • Flush and replace brake fluid
 Severe driving conditions may require more frequent service

Adhering to these intervals helps maintain vehicle performance and prevents the early illumination of the Perform Service light due to overdue maintenance.

Additional Considerations for Perform Service Resets

It is important to note that resetting the Perform Service light without performing the recommended maintenance can lead to neglect of critical vehicle components. The reset procedure is intended to be performed only after completing the required service.

In some cases, if the Perform Service light continues to appear despite resetting and servicing, this may indicate a malfunction in the vehicle’s maintenance reminder system or an unrelated mechanical issue. Professional diagnostic evaluation is advised in such situations.

Ensure the use of genuine RAM parts and recommended fluids when performing maintenance to uphold warranty conditions and vehicle reliability.
