OSRAM LEDCBCTRL102
OSRAM LEDriving Canbus Control Unit
Model: LEDCBCTRL102 (21 Watts)
Brand: OSRAM
Introduction
The OSRAM LEDriving Canbus Control Unit is designed to integrate LED retrofit lamps into a vehicle's electrical system without triggering lamp failure detection warnings. This unit acts as a bypass, ensuring compatibility and preventing error messages on the vehicle's board computer when upgrading to LED fog lights or other LED applications. It is suitable for most vehicle models equipped with a lamp failure detection system.
Safety Information
- Always disconnect the vehicle's battery before performing any electrical work to prevent short circuits or electrical shock.
- Ensure the control unit is installed in a location that is protected from excessive heat, moisture, and physical damage.
- Verify the wattage compatibility of the LEDriving Canbus Control Unit (21W) with your specific LED lamps to ensure proper function and prevent damage.
- If you are unsure about the installation process, consult a qualified automotive technician.
- Do not modify the control unit or its wiring. Unauthorized modifications can lead to malfunction or safety hazards.
Product Overview
The OSRAM LEDriving Canbus Control Unit (LEDCBCTRL102) is a compact device designed to resolve common error messages that occur when installing LED retrofit lamps in vehicles with sensitive lamp failure detection systems. Each unit is engineered for durability and reliable performance.

Setup and Installation
The LEDriving Canbus Control Unit is designed for easy installation. Follow these steps carefully:
- Preparation: Ensure the vehicle's ignition is off and the battery is disconnected. Identify the wiring for the lamp you intend to upgrade to LED.
- Identify Wires: Locate the positive (+) and negative (-) wires for the lamp. You may need a multimeter to confirm polarity.
- Connect the Unit: The Canbus Control Unit should be wired in parallel with the LED lamp. Connect one wire from the control unit to the positive (+) wire of the lamp circuit and the other wire from the control unit to the negative (-) wire (ground) of the lamp circuit. Ensure secure connections using appropriate connectors (e.g., crimp connectors, solder).
- Mounting: Securely mount the control unit to a metal surface on the vehicle chassis. This is important for heat dissipation, as the unit can generate heat during operation. Use the integrated mounting tabs and appropriate screws or bolts.
- Test: Reconnect the vehicle's battery and test the LED lamp. Verify that the lamp functions correctly and that no error messages appear on the dashboard.
- Finalize: Once confirmed, secure all wiring to prevent chafing or damage.

Operation
Once correctly installed, the OSRAM LEDriving Canbus Control Unit operates automatically. It provides the necessary electrical load to simulate a traditional incandescent bulb, thereby preventing the vehicle's lamp failure detection system from registering an error when an LED lamp is used. The unit functions passively, requiring no user interaction after installation.
Maintenance
The OSRAM LEDriving Canbus Control Unit is designed to be maintenance-free. Periodically inspect the wiring connections to ensure they remain secure and free from corrosion or damage. Ensure the unit remains securely mounted to its heat-dissipating surface.
