How to Obtain the CEM & ECM PIN for Your Volvo

To modify the configuration of your vehicle, you will need the CEM (Central Electronic Module) PIN for your Volvo. For example, if you want to add features such as heated seats, activate navigation, remove STOP/START, enable video playback while driving, or enable cruise control, you will need the CEM PIN.

Each Volvo has a unique PIN, known only by Volvo Cars, and they will not disclose this PIN to anyone.

However, there are ways to obtain this PIN. The options vary significantly depending on the platform. You can identify your Volvo platform by:

Entering your vehicle's VIN code in our D5T5 search bar ↑
Looking up our article on Volvo platforms

After obtaining the CEM PIN, you can unlock the option to change the vehicle configuration but not to tune the car.

For tuning, a different type of PIN called the ECM (Engine Control Module) PIN is needed on some platforms.

For a detailed explanation of Volvo PIN codes, read our article.

Please note that we do not supply PIN code readout files when decoding is done via VDASH or VDD. Instead, the PIN codes are automatically uploaded directly to the VDASH system for your use.

Decoding CEM PIN:

VDASH is capable of decoding the CEM PIN of some P1 vehicles (2011+)

‣ Register an account
‣ Download and install VDASH
‣ Connect your car to VDASH using a DiCE or Generic J2534 (you can purchase SUPER J2534 from our e-shop)
‣ Click on “Decode PIN“

The entire decoding process can take up to 24 hours, but usually only takes 8 hours. You can interrupt the process at any time and resume it later, starting at the last decoded position.

Make sure that throughout the process of decoding, your vehicle is:

‣ Connected to the computer via DiCE and USB (not Bluetooth)
‣ Connected to a power source with a minimum of power of 12A
‣ With the ignition on (the car will be in programming mode; all lights and devices will be off during the process)
VDD is capable of decoding the CEM PIN of some P1 vehicles

The success of CEM PIN decoding depends on the numbers contained within the PIN code itself. The decoding process takes approximately 30 minutes, and it is required to have:

‣ Key removed from the ignition
‣ Disconnected battery charger (some chargers interfere with the CAN bus)

Please note that there is no guarantee of successful CEM PIN decoding!

Decoding ECM PIN:

For most P1s, an ECM PIN is not needed for engine optimization. For newer models, typically after 2011, it may be necessary.

In this case, contact one of our dealers who offer this service.
