Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
2-wire LVDS
Transmission of video signals via 2-wire LVDS technology with CIC and CID.
Signal transmission through this 2-wire LVDS line offers four distinct advantages:
- Higher data transfer rate
- Simplified wiring
- Runtime differences between the individual lines are avoided
- Serial 2-wire LVDS data transmission is now much more cost-effective than 8-wire LVDS technology
The main advantage of using serial 2-wire LVDS is the resulting high picture resolution.
A 4-core, shielded cable is used for the 2-wire LVDS technology. The cable consists of the four cores, LVDS+, LVDS-, 2x ground and shielding.
For Electromagnetic compatibility (EMC) reasons, the unused wire is also connected to ground.
In the illustration to the right, the advantages of both cores connected to ground are shown with the aid of field lines.
The capacitive interference of the signals is deflected to ground. The wires connected to ground form a defined potential and cannot act as antennas.
This ensures that additional interference is avoided.

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
