Error display Detected errors are transmitted by the EBS central module to the instrument panel display via the vehicle data bus, and displayed there. Alternatively, in vehicles without such a display, errors can also be reported via a red and a yellow warning light. A separate TCS light then indicates to the driver the on- going TCS control activities. Red Wala: system deactivated Yellow Wala: slight error: e.g. sensor failure (emergency mode) Brake pressure Supply pressure Error recognition and display EBS 5. 19
