  8. Position the EBCM electrical connector (1) to the EBCM.

    9. Lower the lever until the locking tabs are fully engaged.

  9. If installing a new EBCM, program the EBCM. Refer to Electronic Brake Control Module Programming and Setup .
  10. Perform the Diagnostic System Check - Vehicle .
  11. 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 Procedure .
