Understanding the On-Board Diagnostics II (OBD2) system in your Peugeot 3008 is crucial for modern vehicle maintenance and troubleshooting. This system, standard in most cars since the late 1990s, allows you and mechanics to access a wealth of information about your vehicle’s health. For Peugeot 3008 owners, knowing about OBD2 compatibility means being able to diagnose issues efficiently, potentially saving time and money on repairs.
Decoding the OBD2 Port and Pinouts in Your Peugeot 3008
The OBD2 port is your gateway to your Peugeot 3008’s computer system. It’s usually located within easy reach inside the cabin. While the location can slightly vary depending on the model year, you’ll typically find it under the dashboard on the driver’s side. This standardized port is designed to provide access to various diagnostic protocols and vehicle data.
The OBD2 port uses a 16-pin connector, and each pin is assigned a specific function. For Peugeot vehicles, including the 3008, understanding these pinouts can be particularly helpful, especially when using diagnostic tools or interpreting technical information. Here are the common OBD2 pin configurations used in vehicles like the Peugeot 3008:
| Pin Number | Pin Name | Description |
|---|---|---|
| 3 | CAN-H Diag | CAN-Bus (Diagnostic High) |
| 4 | Ground (GND) | Chassis Ground |
| 5 | Signal ground (GND) | Signal Ground |
| 6 | CAN-H Powertrain | Engine-related CAN-Bus (Powertrain High) |
| 7 | ISO9141 K Line | ISO 9141-2 & KWP2000 Communication (K-Line) |
| 8 | CAN-L Diag | CAN-Bus (Diagnostic Low) |
| 14 | CAN-L powertrain | Engine-related CAN-Bus (Powertrain Low) |
| 15 | ISO9141 L-Line | ISO 9141-2 & KWP2000 Communication (L-Line) |
| 16 | Battery voltage | Battery Power Input |
Omitted pins are Not Connected, and this configuration is generally used on 2006 and newer vehicles with CAN-BUS systems, which includes many Peugeot 3008 models.

It’s important to note that older PSA vehicles (Peugeot, Citroen, Renault) produced between 1997 and 2006 might utilize a different VAN-Bus pinout. While less common in Peugeot 3008 models which generally fall into the post-2008 production range, it’s useful context for owners of other PSA vehicles.
Additionally, some Peugeot models might have an alternative pinout configuration for specific diagnostic needs:
| Pin Number | Pin Name | Description |
|---|---|---|
| 2 | K-Line | Heater and air-conditioner diagnostic |
| 3 | Engine rotation sense | |
| 4 | GND | Chassis ground |
| 5 | SGND | Signal ground |
| 6 | CAN-high | J-2284 CAN High |
| 7 | K-Line | Engine and transmission diagnostic |
| 10 | K-Line | Steering wheel module diagnostic |
| 11 | K-Line | Anti-theft, tire pressure, and other module diagnostics (Peugeot 307, 607, 807) |
| 12 | K-Line | ABS diagnostic |
| 13 | K-Line | Airbag diagnostic |
| 14 | K-Line/CAN-low | Lock diagnostic or J-2284 CAN Low |
| 15 | L-Line | Engine and transmission |
| 16 | +12V | Battery+ |
This alternative pinout demonstrates the complexity that can sometimes exist within OBD2 systems, even within the same manufacturer. While less likely to be the primary OBD2 setup for a Peugeot 3008, it highlights the importance of verifying compatibility and understanding potential variations.
Peugeot 3008 OBD2 Compatibility and Protocols
The Peugeot 3008, especially models from 2010 onwards, is generally OBD2 compliant and utilizes the CAN (Controller Area Network) protocol. This is a high-speed communication protocol that’s become standard in modern vehicles. However, OBD2 compliance also involves the diagnostic protocols used for communication.
Peugeot vehicles, including the 3008, can use various OBD2 protocols depending on the model year, engine type, and specific systems being accessed. Common protocols you might encounter include:
- CAN (CAN bus protocols): As mentioned, CAN is prevalent in newer Peugeot 3008 models. Within CAN, there can be variations like CAN 11bit (500kb), CAN 29bit, and ISO 15765-4 CAN.
- KWP2000 (Keyword Protocol 2000): This protocol, also known as ISO 14230-4, is found in some older OBD2 compliant Peugeots. It comes in FAST and SLOW versions, referring to data transmission speeds.
- ISO 9141-2: An older ISO standard protocol, you might find this in some earlier OBD2 Peugeot models.
To give you a clearer picture of compatibility, here’s a snippet from a Peugeot OBD-2 compatibility list, focusing on models around the Peugeot 3008’s era:
| Model | Engine | Year (starting from) | OBD-2 Protocol |
|---|---|---|---|
| Peugeot 3008 | 1.6 HDi, Diesel (110HP) | 2010 | CAN 11bit (500kb) |
| Peugeot 3008 | 2.0 HDi, Diesel (150HP) | 2010 | CAN 11bit (500kb) |
| Peugeot 308 | 1.6 HDi, Diesel (110HP) | 2006 | CAN 11bit (500kb) |
| Peugeot 308 | 1.6 HDi, Diesel (90HP) | 2007 | CAN 11bit (500kb) |
| Peugeot 308 | 2.0 HDi, Diesel (110HP) | 2007 | CAN 11bit (500kb) |
| Peugeot 308 | 1.6 Vti, Gasoline (120HP) | 2007 | CAN 11bit (500kb) |
| Peugeot 5008 | 1.6 HDi 16, Diesel (110HP) | 2010 | CAN 11bit (500kb) |
This table illustrates that Peugeot 3008 models from 2010 onwards, along with contemporary models like the 308 and 5008, predominantly utilize CAN-based OBD2 protocols. When selecting an OBD2 scanner, ensuring CAN compatibility is essential for Peugeot 3008 vehicles.
Using OBD2 for Peugeot 3008 Diagnostics
With OBD2 compatibility, Peugeot 3008 owners can utilize a range of diagnostic tools to:
- Read Diagnostic Trouble Codes (DTCs): Identify the source of issues, often indicated by the check engine light or other warning lights.
- Clear DTCs: Reset the check engine light after addressing the problem (though it’s crucial to fix the underlying issue first).
- View Live Data: Monitor real-time parameters like engine temperature, RPM, sensor readings, and more. This is invaluable for diagnosing intermittent issues or assessing engine performance.
- Perform Basic Tests: Some advanced scanners allow for component testing, like activating sensors or actuators.
For Peugeot 3008, a basic OBD2 scanner will allow you to read and clear engine-related fault codes. More advanced scanners can offer deeper diagnostics into systems like ABS, airbags, transmission, and body control modules, depending on the scanner’s capabilities and the vehicle’s supported protocols.
When choosing an OBD2 scanner for your Peugeot 3008, consider:
- Protocol Compatibility: Ensure it supports CAN protocols, and ideally KWP2000 and ISO 9141-2 for broader Peugeot compatibility if you work on various models.
- Features: Decide if you need basic code reading, live data, or more advanced functions.
- User-Friendliness: Choose a scanner with an interface you find easy to navigate.
By understanding your Peugeot 3008’s OBD2 system and utilizing compatible diagnostic tools, you can take a proactive approach to vehicle maintenance, diagnose problems efficiently, and ensure your car runs smoothly. Remember to always consult your vehicle’s service manual and seek professional advice when dealing with complex automotive issues.
