2. TROUBLESHOOTING PRECAUTIONS
- When there is a malfunction in the contact point of the terminals or
installation problems with parts, removal and reinstallation of the suspected
problem parts may return the system to its normal condition either completely
or temporarily.
- In order to determine the location of the malfunction, be sure to check
the engine 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.
- Since the Vehicle Stability Control system may be influenced by malfunctions
in other systems, be sure to check for DTCs in other systems.
- Be sure to remove and reinstall the hydraulic brake booster and each
sensor with the ignition switch OFF unless specified in the inspection procedure.
- When removing and installing the hydraulic brake booster 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.
- After replacing the skid control ECU (master cylinder solenoid) and/or
the yaw rate and acceleration sensor (airbag sensor assembly), be sure to
perform the yaw rate sensor and acceleration sensor zero point calibration
(See page
).
- The CAN communication system is used for communication between the skid
control ECU (master cylinder solenoid), steering angle sensor (spiral cable
sub-assembly), yaw rate and acceleration sensor (airbag sensor assembly)
and other ECUs.
- If there is trouble in the CAN communication line, the DTC relating
to the communication line is output. If a DTC relating to the CAN communication
line is output, repair the malfunction in the communication line and troubleshoot
the Vehicle Stability Control system.
- Since the CAN communication line has a specific length and route, it
cannot be repaired temporarily with a bypass wire.
