2. TROUBLESHOOTING PRECAUTIONS
(a) When there are malfunctions with terminal contact points or part installation problems, removal and
installation of the suspected problem parts may return the system to the normal condition either
completely or temporarily.
(b) In order to determine the malfunctioning area, check the conditions at the time the malfunction occurred,
such as DTC output and the Freeze Frame Data, and record them before disconnecting each connector or
removing and installing parts.
(c) Since the system may be influenced by malfunctions in systems other than the VSC system, be sure to
check for DTCs in other systems.
3. HANDLING PRECAUTIONS
(a) Do not remove or install VSC parts such as the steering angle sensor (spiral cable with sensor
sub-assembly) or yaw rate and acceleration sensor (airbag sensor assembly) except when required, as
they cannot be adjusted correctly after removal or installation.
(b) Be sure to perform preparation before work and confirmation after work is completed by following the
directions in the repair manual, when working on the VSC system.
(c) Be sure to remove and install the ECU, brake actuator and each sensor, etc. with the ignition switch off
unless otherwise specified in the inspection procedure.
(d) If the ECU, brake actuator or a sensor has been removed and installed, it is necessary to check the system
for problems after the parts have been reassembled. Check for DTCs using the Techstream, and also check
that system functions and signals received by the ECU are normal using Test Mode (signal check).
(e) If replacing the skid control ECU (brake actuator assembly), always replace it with a new one (if the skid
control ECU (brake actuator assembly) is not replaced with a new one, DTCs may be stored).
