PRECAUTION [DYNAMIC STABILITY CONTROL (DSC)]

find out the causes of DSC malfunction, use these on-board
diagnostic results.
If a malfunction occurred in the past but is now normal, the cause is
likely a temporary poor connection of the harness. The control
module usually operates normally. Be careful when searching for the
cause of malfunction.
After repair, it is necessary to clear the DTC from the control
module memory. Also, if the DSC related parts have been replaced,
verify that the no DTC has been displayed after repairs.
After repairing the ABS wheel-speed sensor or ABS sensor rotor, or
after replacing the control module, the ABS warning light may not
go off even when the ignition is switched to ON. In this case, drive
the vehicle at a speed of
more than 10 km/h {6.2 mph}
, make
sure the ABS warning light goes off, and then clear the DTC.
When repairing, if the DSC related connectors are disconnected and
the ignition is switched to ON, the control module will mistakenly
detect a fault and record it as a malfunction.
CAUTION:
When any DSC HU/CM (brake fluid pressure
sensor), SAS control module (yaw rate sensor, low-
G sensor) are replaced. Perform the sensor
standard point installation of each sensor.
To protect the control module, make sure the ignition is off before
connecting or disconnecting the control module connector.
b. Malfunctions in hydraulic system
Symptoms in a hydraulic system malfunction are similar to those in
a conventional brake malfunction. However, it is necessary to
determine if the malfunction is in a DSC component or the
conventional brake system.
The hydraulic unit contains delicate mechanical parts. If foreign
materials get into the component, the DSC may fail to operate.
Also, it will likely become extremely difficult to find the location of
the malfunction in the event that the brakes operate but the DSC
does not. Make sure foreign materials do not get inside when
servicing the DSC (e.g. brake fluid replacement, pipe removal).
Intermittent Concern Troubleshooting
Vibration method
If malfunction occurs or becomes worse while driving on a rough road or when engine is
vibrating, perform the steps below.
NOTE:
There are several reasons why vehicle or engine vibration could cause an electrical
