When there is a malfunction in the contact point of the terminals or installation problems with parts, removal and installation of the suspected problem parts may return the system to the normal condition either completely or temporarily.
In order to determine the malfunctioning area, be sure to check the conditions at the time the malfunction occurred, such as by DTC output and freeze frame data output, and record it before disconnecting each connector or removing and installing parts.
Since the ABS with EBD systems may be influenced by a malfunction in the other systems, be sure to check for DTCs in the other systems.
Be sure to remove and install the brake actuator and each sensor with the ignition switch off unless specified in the inspection procedure.
When removing and installing the brake actuator and each sensor, be sure to check that the normal display is output in the test mode inspection and in DTC output inspection after installing all parts.

NOTE: When disconnecting the negative (-) battery terminal, initialize the following systems after the terminal is reconnected.
