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.
There are several ways to obtain this PIN. The available options vary significantly depending on the Volvo 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.
Decoding CEM PIN
Option 1: Decode with VDASH
VDASH is capable of decoding the CEM PIN of some P1 vehicles, usually 2011+.
- Register an account
- Download and install VDASH
- Connect your car to VDASH using a DiCE or Generic J2534, such as SUPER J2534 from our e-shop
- Click on Decode PIN
The entire decoding process can take up to 24 hours, but usually takes around 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, your vehicle is:
- Connected to the computer via DiCE and USB, not Bluetooth
- Connected to a power source with a minimum power of 12A
- With the ignition on. The car will be in programming mode; all lights and devices will be off during the process.
Option 2: Decode with VDD
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.
Requirements:
- Key removed from the ignition
- Disconnected battery charger, because some chargers interfere with the CAN bus
Other CEM PIN Options
- Send us your CEM, which we will decode within 48 hours and send back.
- Find your nearest PRO / PRO Verified dealer
Decoding ECM PIN
For most P1 vehicles, 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.
