This article shows a guide on how to use Honda HDS to regenerate Honda Diesel Particulate Filter. Check these operations; you will not only gain the skill to regenerate DPF on your Honda vehicle by yourself but also save a dozen dollars.
Procedures:
Prepare the Vehicle
-
- Make sure the engine temperature reaches around 76°C or at least close to it.
- Park the vehicle in a safe place where engine noise won’t disturb others, and ensure there’s no flammable material beneath the car (as the DPF temperature can rise above 600°C).
- Open the hood.
- Disable all unnecessary electrical components (e.g., interior lights), and avoid turning them back on during the process.
Setup the Honda HDS System
-
- Connect the HIM (Honda Interface Module) to the car and your computer.
- Start the Honda HDS software.
- Turn the ignition switch to the “II” position.
- In HDS, press “Select a new vehicle” and enter the mileage.

Select the System
-
- Navigate to the “System” menu.
- Select “Diesel.”

Check for Diagnostic Trouble Codes (DTCs)
-
- In the DTC menu, select “DTC – given frozen data” and delete any existing codes.
- Ensure there are no issues with DPF sensors. If sensor problems exist, resolve them before proceeding.

Access Regeneration Settings
-
- Go back to the “Settings” menu.
- Select “DPF Regeneration.”

Start the Engine
-
- Turn on the engine.
- Activate the headlights and switch the air conditioner to ON mode.
Monitor Engine Temperature
-
- If the engine temperature is insufficient, the HDS will prompt you to accelerate the engine to a range between 1600 and 2400 RPM.
- Once the required temperature is reached, release the accelerator as the HDS takes control.
Regeneration Process
-
- During regeneration, the engine will automatically increase to 3000 RPM and stabilize at 1500 RPM.
- After completing regeneration, the engine will briefly return to 3000 RPM to cool down the exhaust line.

Final Steps
-
- Exit the Honda HDS program.
- Turn off the engine.
- Disconnect the HIM cables.
- Take the car for a short drive to ensure the exhaust line cools down properly.
Done!
