2.Precautions during servicing of DSC. The DSC is composed of electrical and mechanical parts. It is necessary to categorize malfunctions as being either electrical or hydraulic when performing troubleshooting.<\/p>\n

\n

\n
(1)Malfunction in electrical system<\/dd>\n
\n
\n
\n
\u2022 The control module has an on-board diagnostic function. With this function, the ABS warning light and\/or brake system warning light and\/or TCS\/DSC indicator light and\/or DSC OFF indicator light will come on when there is a problem in the electrical system. Also, past and present malfunctions are recorded in the control module. This function can find malfunction that do not occur during periodic inspections. Connect the M-MDS to the DLC-2. The stored malfunctions will be displayed in the order of occurrence. To find out the causes of DSC malfunction, use these on-board diagnostic results.<\/div>\n
\u2022 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.<\/div>\n
\u2022 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.<\/div>\n
\u2022 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}<\/span>, make sure the ABS warning light goes off, and then clear the DTC.<\/div>\n
\u2022 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.<\/p>\n
\n
\n
Caution<\/div>\n<\/dd>\n
\n
\u2022 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.<\/div>\n<\/dd>\n<\/dl>\n<\/div>\n
\u2022 To protect the control module, make sure the ignition is off before connecting or disconnecting the control module connector.<\/div>\n<\/dd>\n<\/dl>\n<\/dd>\n<\/dl>\n
\n
(2)Malfunctions in hydraulic system<\/dd>\n
\n
\n
\n
\u2022 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.<\/div>\n
\u2022 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).<\/div>\n<\/dd>\n<\/dl>\n<\/dd>\n<\/dl>\n

3.Clunk \/ bang \/ buzz noise during first forward movement after sitting<\/p>\n

\n

\n
\n
\u2022 A slight clunk\/bang\/buzz noise or jolt from the front of the vehicle is considered normal if it occurs during the vehicle’s first forward movement after starting the engine. This is a normal operating noise of the dynamic stability control (DSC). Do not attempt any repairs.<\/div>\n
\u2022 If a customer complains about this, explain that the noise comes from the ABS\/TCS\/DSC \u201cMalfunction Detection Function\u201d initial check and that there is no problem.<\/div>\n
\u2022 This initial check is a necessary function to ensure the normal operation of the ABS\/TCS\/DSC system. It occurs when the vehicles first moves forward under the following conditions.<\/div>\n<\/dd>\n<\/dl>\n<\/div>\n
