How does Honda HDS HIM perform forced regeneration of DPF?

This blog is a tutorial for you to perform forced regeneration of DPF using HondaHDS HIM diagnostic tool. Let’s go straight to the point!

First question: Replace DPF or regenerate DPF filter?

The correct decision must take into account the vehicle’s intended use and driving style. If the vehicle is to be used for short, stop-start journeys, with few frequent, then removal is recommended. If the vehicle will be driven hard, with high frequency long journeys, then it’s better to regenerate DPF to save cost.

Second question: How to use Honda HDS HIM perform forced regeneration of DPF?

(This guide demonstrates Honda Civic 8 as an example.)

Tool you need:

1.     Honda HDS HIM

2.     RS232 Convert Connector/ Adapter

Before starting you should make sure:

- You need a PC laptop with stable power charge and avoid power cut during the operation.

- The process takes about 30min. So either you stay in the car while time is still on or off with the PC: not to go back in the car during the regeneration, avoids interactions with it to avoid problems.

- If you use an adapter Com (232) -> USB, verify that the com port is set to COM1. The interface does not work on another COM port!

- Check the oil level before and after regeneration. If after regeneration, the oil level is too high or if it stinks diesel will require draining.

- Disable the energy saving USB, antivirus, internet and all that can use PC resources.

Steps to regenerate DPF filter:

1)    To start regeneration, you should first make the car exhaust get to a hot enough temperature, ideally around 600 degrees Celsius. Open the hood and disable all pump energy (ceiling, etc ...) and especially not fun to reactivate during operation.

2)    Connect the Honda HDS scanner with car and laptop. Start Honda HDS software then turn car ignition on to position II.

3)    Press the "Select a new vehicle" and enter the mileage.

Select "System" then "Diesel"

4)    Check and delete the DTC, menu "DTC - given frozen". It’s necessary to remove DTC codes before operation and also check the various sensors of the DPF.

After that go back to "Settings" and select "DPF Regeneration"

5)    Put the engine keep running. Turn on the lights and the air conditioner. (If the engine is not the right temp, HDS will ask to accelerate between 1600 and 2400trs/min. When the temp is reached, HDS takes over, release the accelerator.)

6)    Allow HDS to regeneration. The engine mounts alone at 3000trs/min during regeneration. It is stagnant at 1500 trs/min. At the end of the regeneration scheme dates back to 3000 trs/min to cool the exhaust line (weird, but it is like here)

7)    When the regeneration is complete, quit HDS, turn off engine, remove the cables from HIM and go for a ride to make sure the cooling line. In this way you can use Honda HDS HIM diagnostic tool to regenerate DPF to save lots of money!
