How to Reset Mack and Volvo EPA 07 to GHG17 Engines Using JPRO

Resetting the parameters or performing adaptations for Mack and Volvo EPA 07 to GHG17 engines is an essential process for ensuring optimal performance after maintenance, such as DPF replacement or SCR system servicing. The JPRO Diagnostics tool simplifies this procedure. In this blog post, we will guide you through the steps for resetting these engines using the JPRO tool.

Steps to Reset Mack and Volvo Engines with JPRO

1. Connect the Tool

- Begin by plugging the JPRO diagnostic tool into the vehicle’s diagnostic port (either a 9-pin or 16-pin connector, depending on your vehicle).

- Ensure that the laptop or tablet running the JPRO software has a stable power supply to prevent any interruptions during the process.

2. Launch JPRO and Connect

- Open the JPRO Diagnostic Software on your device.

- From the interface, select the specific Mack or Volvo vehicle you are working on.

- Wait patiently for JPRO to establish communication with the engine control unit (ECU) and display the relevant engine data.

3. Access Engine Reset Functions

- Navigate to the Aftertreatment System or Engine Service menu within the JPRO software.

- Look for the options related to Reset Functions. Depending on the engine model and after-treatment system, you may find options such as:

- DPF Ash Accumulator Reset

- SCR System Reset

- DEF Dosing System Reset

- EGR Adaptation Reset (if applicable)

4. Perform Resets

- Choose the appropriate reset option based on the maintenance service performed:

- DPF Reset: If you have cleaned or replaced the DPF filter, select "Aftertreatment DPF Service Reset."

- SCR/DEF System Reset: If you replaced components of the SCR system, DEF tank, or doser valve, initiate the SCR System Reset.

- EGR Adaptation Reset: For repairs related to the EGR system, perform the EGR Valve Reset or Adaptation.

- Follow the on-screen prompts to confirm the action. JPRO may require you to ensure certain conditions are met, such as:

- The engine being off or idling, depending on the reset performed.

- No active fault codes that could interfere with the resetting process.

5. Clear Fault Codes

- After completing the necessary resets, navigate to the Fault Code section within JPRO.

- Clear all inactive or historical fault codes related to the maintenance tasks you performed.

6. Verify Success

- Conduct a Post-Repair Diagnostic Scan to ensure:

- There are no active fault codes remaining.

- The engine and after-treatment system are operating within specified parameters.

- Monitor live data for key performance indicators such as soot levels, DEF dosing rates, and SCR efficiency.

Tips for Success

- Software Version: Ensure your JPRO software is updated to support the specific Mack and Volvo EPA 07 to GHG17 engines.

- Stable Connection: Use a reliable diagnostic adapter (e.g., Nexiq, Dearborn, or JPRO’s own adapter) to prevent any connection disruptions.

- Check Pre-Conditions: Confirm that all maintenance procedures have been completed accurately before performing any resets.

- Document Changes: Keep a detailed record of the resets and related service procedures for future reference.

In conclusion, using JPRO to reset Mack and Volvo EPA 07 to GHG17 engines is a straightforward process that, when done correctly, helps maintain the efficiency and performance of your vehicle. Always ensure you follow the outlined steps and tips for the best results. Happy diagnosing!
