Abs Control Unit
WARNING: This page is about a different car, the 1999 Acura 3.0CL and 1999 Acura 2.3CL. However, it is still accessible from the selected car via links, so may be relevant.
ABS control unit's main function is to detect wheel speed based on wheel speed sensor signals it receives, then calculate vehicle speed based on detected wheel speed. It calculates the slip rate of each wheel, and transmits control signal to modulator solenoid valve when slip rate is high.
