How to replace ABS Modulator Control Unit on Acura Integra?

The details are mentioned below:---

Modulator Control Unit

The Modulator Control Unit (MCU) contains solenoid valves for each wheel. These valves are independent of each other and are positioned vertically for improved maintainability. The modulators for the rear wheels act as proportioning control valves to prevent the rear wheels from locking up in the event the anti-lock braking system is malfunctioning or not activated.
