CAN Gateways

What is CAN Bus? CAN (Controller Area Network) bus is a modern, digital way of connecting devices in your vehicle. For example, in most 2006 and later Volkswagens, speed information is relayed to the Engine Control Unit from the Anti-lock Brake System controller via (and only by) the CAN bus. Information from the Engine Control Unit to the Speedometer is also only relayed by the CAN bus.

In order to have these newer motors function correctly, we need to convert the digital CAN signals to conventional analog signals and vice versa.

Hasenwerk CCS Korrekt

Hasenwerk CCS Korrekt

This is a “NOT gate” or inverter circuit. When the Input is 12V the Output will be GND. When the Input is GND the Output is 12V.

Use Example #1: Brake Input Correction

1999.5 and later Volkswagen ECUs have two brake inputs that are opposite signals from each other that must switch at the same time or else you will have an "implausible input" and the ECU will throw a check engine light. This silent solid state switch will ensure that "F" and "F47" inputs will switch at the same time and all that is required is to connect this to the brake light circuit, no additional brake switch is required.

Use Example #2: Revered Polarity Status Lights

If you have a check engine or glow plug light that uses a switched 12V input as opposed to the switched ground that the Volkswagen ECU provides, the Hasenwerk CCS Korrect will resolve that problem.

Compatibility: Universal

Vehicle Speed Sensors

A Vehicle Speed Sensor or VSS is a device that measures the speed of a vehicle by reading the speedometer, CV joint, Universal Joint, drive shaft or similar rotation and converting that motion into electrical signals that read by the the engine's computer, speedometer, cruise control or similar system.

Most Volkswagen Audi Group product before 2006 want to see a speed input ratio of 1Hz to 1km/h. In other words, at 100km/h (62mph) the input frequency for a speedometer or Engine Control Unit needs to be 100Hz. 2006 and later vehicles use CAN bus to communicate speeds to the ECU.

If the VSS is going to be used to only for Cruise Control or Engine Management purposes 100% accurate speed isn't necessary as they need to know if you are moving and if so, are accelerating, decelerating or maintaining a constant speed. If you are looking for 100% accurate measurement for speedometer use then a signal calibration unit may be necessary as well.

Hasenwerk Universal VSS

Hasenwerk Universal VSS

This is a simple, IP67 waterproof, universal Vehicle Speed Sensor for most vehicles with CV joints or a drive-shaft. One pulse per bolt - no external magnets are needed. This video details an example installation.
