C0043 - Chassis Fault Code C0043 - ABS / Bromssystem (Hjulhastighetssensorer & Ventiler)

DTC C0043 denotes an electrical or rationality malfunction within Brake Pedal Switch Circuit 'B'. Modern braking and chassis management architectures employ redundant switch logic (typically a Normally Open circuit 'A' combined with a Normally Closed circuit 'B', or dual Hall-effect sensors). The control module (ABS/ESP, BCM, or ECM) continuously cross-references these signals. C0043 triggers when Circuit 'B' experiences an open circuit, short to ground/voltage, excessive contact resistance, or timing correlation mismatch against Circuit 'A'.
