ECU 4008640090 ABS 12V

The WABCO ECU-ABS E4C 4008640090 is an electronic control unit (ECU) for anti-lock braking systems in heavy-duty trucks. Configured for a 4S/4M setup (four wheel-speed sensors and four modulator valves), this module interprets sensor signals and commands the modulators to modulate air pressure—preventing wheel lock-up and enhancing vehicle stability under braking.
