Hello everyone, I tried Diagbox with OpenPort 2 but it doesn't work. It sees the interface but doesn't recognize anything.

Hello everyone, I tried DiagBox with OpenPort 2 but it doesn't work; it sees the interface but...

Hello,

OpenPort 2.0 with DiagBox can be problematic because DiagBox is natively designed for the PSA VCI (Lexia 3 / PP2000). Here are the points to check:

1. Driver and configuration
  • Did you install the PSA VCI Driver provided in the package before launching DiagBox?
  • OpenPort 2.0 must be recognized in J2534 PassThru mode. Check in Windows Device Manager that it appears correctly (no yellow exclamation mark).

2. Interface selection in DiagBox
  • By default, DiagBox looks for a PSA VCI (Lexia). If you are using a J2534, you may need to force the selection of the PassThru interface in DiagBox settings.
  • Check under Configuration → Interface whether you can select J2534 / PassThru mode instead of the native VCI.

3. Vehicle and connection
  • Ignition on (ON position, not just accessories)?
  • Is the OBD connector firmly plugged in?
  • What vehicle exactly (modmodel, year, engine)? Some older modmodels use specific connectors in addition to OBD2.

4. Actual compatibility

Honestly, DiagBox + OpenPort 2.0 compatibility is not guaranteed across all versions. DiagBox 9.85 works reliably mainly with:
  • The actual PSA VCI (Lexia 3 / PP2000 clone or original)
  • Some Chinese VCI clones with the correct drivers

OpenPort 2.0 is excellent in J2534 mode for other software (Ford, Mazda, etc.), but support with DiagBox is limited.

Tell us the vehicle modmodel and the exact error message you get, and we can better narrow down the problem.

Hello, it's a 2006 Citroen C4 Grand Picasso, I have an OpenPort 2 and a Chinese PSA XS Evolution clone, I've been at it for 2 weeks.

OpenPort 2 not working

Hi,

I understand your frustration after 2 weeks. Here is the main issue:

C4 Grand Picasso 2006 — Important point

The 2006 C4 Grand Picasso is a mixed CAN / K-Line vehicle. Some ECUs on this modmodel still communicate via K-Line (ISO 9141), not only via CAN. This is often why DiagBox "sees the interface" but "does not recognize anything" on the vehicle.

Why your interfaces do not work

  • OpenPort 2.0 — It is a J2534 PassThru. DiagBox 9.85 does not support it natively; it looks for a PSA VCI. It will not work without advanced modifications.
  • Chinese PSA XS Evolution clone (not Full Chip) — This is your real problem. Non-Full Chip clones generally do not have the K-Line chip (often the L9637D chip is missing or replaced by an empty component). On a 2006 C4, without a working K-Line, you will not be able to communicate with several ECUs.

What you need

For your vehicle specifically, you need a Lexia 3 / PP2000 Full Chip clone with:

  • Main NEC chip (not a generic chip)
  • K-Line chip L9637D present and soldered
  • Firmware Rev.C or higher
  • Working CAN chip

How to check your current clone

Open the case of your XS Evolution and check:
  • Are all components soldered onto the PCB? (non-Full Chip units have empty slots)
  • Look for the chip marked L9637D — if it is missing, that confirms it: no K-Line
  • Take a photo of the PCB and post it here; we can tell you exactly what is missing

Quick solution

A Full Chip Lexia 3 PP2000 clone with an NEC chip can be found for €25–40 on the usual marketplaces. Specifically look for "Full Chip 921815C" or "Diagbox Full Chip NEC relay". This is the only investment that will solve your problem properly.

In the meantime, neither the OpenPort 2.0 nor your current clone will work properly with DiagBox on this 2006 C4.

Hi help me I'm looking for a Citroen Peugeot service box

Hi help me I'm looking for a Citroen Peugeot service box

Just to clarify — Service Box and DiagBox are two different tools:

  • Service Box (Sedre) — PSA's parts catalogue and technical documentation system (wiring diagrams, repair procedures, part numbers, service times). It does not do diagnostics.
  • DiagBox — PSA's diagnostic software (fault codes, live data, actuator tests, coding). This is what's available in the resource linked in this thread.

Which one do you actually need?

If you need wiring diagrams, part numbers and repair info → you need Service Box.
If you need fault code reading, diagnostics and coding → you need DiagBox (available above).

About Service Box:
Service Box was discontinued by PSA and replaced by their online portal. The last offline version commonly found is Service Box 2014. It typically runs on Windows 7 or XP (compatibility issues on Win10/11). It requires a virtual machine or compatibility mode in most cases.

Let us know which one you're after and what vehicle/year you're working on, and we can point you in the right direction.

Alright, you will need to set up a virtual machine. The most common method is to use VirtualBox or VMware with a Windows XP or Windows 7 operating system.

Here is a general guide, but keep in mind that finding a working installation of Service Box 2014 can be complicated and often requires modifying specific files to make it work offline.

1. Install the virtual machine software :
* Download and install VirtualBox (free) or VMware Workstation Player (free for non-commercial use).

2. Obtain a Windows operating system image :
* You will need an ISO image for Windows XP (SP3 recommended) or Windows 7 (the 32-bit version is often more compatible with older software).
* You will also need a valid product key for the operating system.

3. Create a virtual machine :
* Open VirtualBox/VMware.
* Create a new virtual machine.
* Allocate a sufficient amount of RAM (for example, 2 GB for XP, 4 GB for Win7) and disk space (for example, 40–60 GB).
* Configure the virtual machine to boot from the Windows ISO image.
* Install the chosen Windows operating system inside the virtual machine.

4. Install Guest Additions/VMware Tools :
* After installing the operating system, install Guest Additions (VirtualBox) or VMware Tools (VMware). This improves performance, screen resolution, and allows folder sharing.

5. Find and install Service Box 2014 :
* This is the most difficult part. Service Box 2014 is no longer officially distributed. It can generally be found on various forums or file-sharing sites. Pay the utmost attention to sources and potential malware.
* Look for a version that is already cracked or includes instructions on how to crack it for offline use. You will likely need specific database files and activation executable files.
* Generally, installation involves:
* Running an installer.
* Replacing certain system files with cracked versions.
* Configuring the database path.
* Sometimes, it is necessary to run a specific activation program.
* It is essential to make sure you are NOT connected to the Internet during installation and activation, as this could irreparably damage the software or trigger online checks.

6. Configuration :
* Once installed and activated, you may need to configure specific settings within the Service Box application itself, such as the VIN database path.

Important considerations:

  • Legality : distributing or using pirated software may be a legal gray area. This information is provided for educational purposes, based on common practices in the community.
  • Security risks : downloading software from unofficial sources carries significant risks of malware, viruses, or ransomware. Always use reliable antivirus and anti-malware software and scan all downloaded files.
  • Compatibility : Even with a virtual machine, Service Box can be temperamental. You may need to try different operating system versions (XP versus Win7), different virtualization software, or different cracked versions of Service Box.
  • Updates : do not attempt to update Service Box once installed, as this could compromise offline activation.

You will need to search for "Service Box 2014 download", "Service Box 2014 сrаск" or similar terms on automotive forums or file-sharing sites. Look for guides specifically for running it in a virtual machine.

Is there a specific vehicle year or model that you are mainly interested in finding ricambi/schemi for? This can sometimes be useful when searching for specific versions or patches.
I already have a virtual machine; I only need the software.
