Troubleshooting Precaution

• When there are malfunctions in the contact points of the terminals or installation problems with any parts, removal and installation of the suspected problem parts may return the system to its normal condition, either entirely or temporarily.

• In order to determine the location of the malfunction, be sure to check the conditions from 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.

• Since the anti-lock brake system may be influenced by malfunctions in other systems, be sure to check for DTCs in other systems.

• 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 and each sensor, be sure to check that the normal display is output during a test mode inspection and a DTC output inspection after reinstalling all the parts.

• If the DTC of the CAN communication line is output, repair the malfunction in the communication line and then troubleshoot the anti-lock brake system.

• Since the CAN communication line has its own length and route, it cannot be repaired temporarily with a bypass wire, etc.
