Check: 

• the control module is correct (compare to the old one)
• that none of the pins on the connector are damaged
• that there are no contaminants on the mating surfaces between the control module and the ABS hydraulic modulator
• that no parts of the old control module seals remain on the old ABS hydraulic modulator valves.
