BRAKE CONTROL – ANTI-LOCK BRAKE SYSTEM
BC–1
ANTI-LOCK BRAKE SYSTEM
PRECAUTION
1. 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.
