  18. Connect the brake booster vacuum sensor electrical connector.
  19. Connect the brake fluid level indicator switch electrical connector.
  20. If a new EBCM was installed, program the EBCM. Refer to Control Module References .
    21. NOTE: A new BPMV comes with both the primary and secondary circuits pre-filled with brake fluid. If the ignition key has not been cycled after installation, only a base brake bleed is necessary.
  21. Bleed the hydraulic brake system. Refer to Hydraulic Brake System Bleeding (Pressure) or Hydraulic Brake System Bleeding (Manual) .
  22. Perform the Diagnostic System Check - Vehicle .
  23. Observe the brake pedal feel after performing the diagnostic system check. If the pedal now feels spongy, air may have been introduced into the secondary hydraulic circuit of the brake modulator which then may have been introduced into the primary circuit. If the pedal feels spongy, perform the Antilock Brake System Automated Bleed .
