The Clean Energy control unit (CESG) detects a crash situation if the safety battery terminal drops.
A crash is detected when the detected absolute voltage difference (between the lines of fuses F30 and F34) is more than 5 Volts. The fault stated below is then stored.
Detection of a crash situation leads to a restriction in many CESG functions (switch of the pneumatic system (valves and outlets) from active to inactive, etc.).
Within the framework of the test module for this component, the following fault is covered:
