Understand your Check Engine Light: Quickly understand what those active fault codes mean with detailed information to help you know what is going on.
Identify the cause and take action: Get detailed explanations of fault codes specific to Cummins engines. You can use this information know what to do and how to proceed.
Track how many times they that fault occurred: You will see the count and be able to use that information to track if this is the first time this issue is coming on or it's an ongoing issue.
It doesn't just cover your engine: You will notice we cover transmission, abs, chassis, cab & body as well. We try to report to you everything that is going on with your vehicle.
Resetting Fault Codes: The reset of fault codes covers both active and Inactive codes.
Active codes: These are alerts for current issues that need immediate attention.
Inactive codes: These are records of past problems. They’re helpful for spotting patterns or issues that might come back again.
Reset all modules: We perform the reset on all the available modules that we are connected to, including transmission, body, cab & chassis systems.
Importance of resetting codes: Clearing these codes after you fix an issue keeps the diagnostic system focused only on what’s currently active. This is crucial for verifying that repairs were successful and for maintaining accurate, up-to-date vehicle diagnostics.
Reset aftertreatment
Purpose: This essential feature enables users to reset the Engine Control Module (ECM), facilitating the regeneration of the Diesel Particulate Filter (DPF) following maintenance or replacement of exhaust system components.
Usage: The reset should only be used under severe fault conditions after necessary repairs have been made, ensuring the system is correctly recalibrated and ready for operation.
Typical repairs include:
Diesel Oxidation Catalyst replacement: Necessary for restoring the efficiency of emissions reduction.
Diesel Particulate Filter servicing or replacement: Important for removing soot build-up and maintaining exhaust flow.
Hydrocarbon Injector Unit repair or replacement: Critical for accurate fuel delivery to the exhaust stream, facilitating effective regeneration.
2637 (Diesel Oxidation Catalyst Face Plugged) and 1922 (Severe Diesel Particulate Filter Soot Load): Highlight significant blockages that can hinder engine performance.
2638 (Diesel Oxidation Catalyst Low Efficiency) in heavy-duty engines: Signals a decline in the ability to process exhaust pollutants efficiently.
Using the Reset Aftertreatment function is vital to ensure that the aftertreatment system continues to operate efficiently and effectively after extensive repairs.
Aftertreatment maintenance filter installation
When replacing or cleaning the Diesel Particulate Filter (DPF) in a truck, it’s essential to also update the Engine Control Module (ECM).
This step ensures the truck’s computer system recognizes the new or cleaned DPF filter and adjusts the engine operations to accommodate the change, optimizing performance and emissions control.
Why notify the ECM about the new DPF?
Boost DPF filter efficiency: By updating the ECM, it configures the engine settings to adapt to the new or cleaned DPF, enhancing its initial efficiency and effectiveness in capturing particulate matter.
Forced DPF regen recommended: Post-installation, it's advisable to perform a forced DPF Regen. This process burns off any residual particles that may hinder the new filter’s functionality, ensuring optimal operation.
Forced DPF regen
The Diesel Particulate Filter (DPF) captures soot during engine operation. To clear this soot, the DPF periodically undergoes active or passive regen, usually automatically, while the engine runs.
When to use:
Fault codes: Some fault codes require you to run a forced DPF regen in order for certain fault codes to clear. This is because the emission system wants to run through all the system checks before the fault codes is cleared.
Driving conditions: If regular driving doesn't achieve the engine load and temperature necessary for active regen, then a forced DPF regen becomes essential. This is often required in situations involving excessive idling or operations under light loads.
High soot: If soot accumulation surpasses what normal regeneration can handle, a forced DPF regen is necessary to prevent blockages.
Benefits:
Ensures efficiency & reliability: It maintains the DPF’s effectiveness and extends its lifespan.
