vehicle condition (vehicle stationary, vehicle moving, speed sensor defective).
Indicator lamp actuation
The signals from the brake pad wear contacts and parking brake are recorded by the ESP control module. They are transmitted to the instrument cluster
(A1) via CAN data buses together with the signals for the ABS, ETS and ESP indicator and malfunction indicator lamps.
