Removal Procedure

NOTE: To prevent equipment damage, never connect or disconnect the wiring harness connection from the EBCM with the ignition switch in the ON position.

Turn OFF the ignition.
Important:

The area around the electronic brake control module (EBCM) must be free from loose dirt to prevent contamination of dissembled ABS components.
Thoroughly clean all of the contaminants from and around the EBCM assembly.
Important: It is not necessary to drain the coolant or disconnect the coolant lines when moving the coolant bypass valve.
