Anti-Lock Brake System: Precaution: Precaution

When there is a malfunction in the contact point of the terminals or installation problems with any parts, removal and reinstallation of the suspected problem parts may return the system to the normal condition either completely or temporarily.
In order to determine the location of the malfunction, be sure to check the conditions at the time the malfunction occurred, through data such as DTC and freeze frame data outputs. Record this information before disconnecting any connectors and removing or installing any parts.
Be sure to remove and install the brake actuator and each sensor with the ignition switch off, unless specified in the inspection procedures.
When removing and installing the brake actuator assembly and each sensor, be sure to check that the normal display is output during a test mode inspection and a DTC output inspection after installing all the parts.
