4. Send the command while depressing on the brake pedal and attempting to rotate the wheel being 

inspected.  

5. While brake pressure is maintained and a DSC/RSC HU/CM operation click sound is heard, confirm that 

the wheel does not rotate. While brake pressure is being reduced and an DSC/RSC HU/CM operation 
click sound is heard, confirm that the wheel rotates. 

Performing the inspection above determines the following: 

The DSC/RSC HU/CM brake lines are normal.  

The DSC/RSC HU/CM hydraulic system is not significantly abnormal (including DSC/RSC 
HU/CM).  

The DSC/RSC HU/CM internal electrical parts (solenoid, motor and other parts) are normal. 

The DSC/RSC unit and DSC/RSC HU/CM output system wiring harnesses (solenoid valve, 
relay system) are normal.  

However, the following items cannot be verified. 

Malfunction with intermittent occurrence of the above items  

Malfunction of DSC/RSC HU/CM input system wiring harnesses and parts  

Extremely small leaks in the DSC/RSC HU/CM internal hydraulic system

The DSC/RSC HU/CM brake lines are normal.  

The DSC/RSC HU/CM hydraulic system is not significantly abnormal (including DSC/RSC 
HU/CM).  

The DSC/RSC HU/CM internal electrical parts (solenoid, motor and other parts) are normal. 

The DSC/RSC unit and DSC/RSC HU/CM output system wiring harnesses (solenoid valve, 
relay system) are normal.  

However, the following items cannot be verified. 

Malfunction with intermittent occurrence of the above items  

Malfunction of DSC/RSC HU/CM input system wiring harnesses and parts  

Extremely small leaks in the DSC/RSC HU/CM internal hydraulic system  

DSC/RSC HU/CM REMOVAL/INSTALLATION 

1. Remove the battery and battery tray. (See BATTERY REMOVAL/INSTALLATION [MZI-3.7] .)  

2. Remove the battery tray bracket as shown in the figure.  

3. Remove the windshield wiper arm and blade. (See WINDSHIELD WIPER ARM AND BLADE

5. Remove the wiper motor. (See WINDSHIELD WIPER MOTOR REMOVAL/INSTALLATION .)  

6. Remove the cowl panel. (See COWL PANEL REMOVAL/INSTALLATION .) 

WARNING:

If the DSC/RSC sensor initialization procedure is not completed, it 
could result in an unexpected accident due to the DSC/RSC being 
inoperative. Therefore, after the DSC/RSC HU/CM is replaced, always 
perform the DSC/RSC sensor initialization procedure to ensure 
proper DSC/RSC operation. (See DSC/RSC SENSOR INITIALIZATION 
PROCEDURE.)  

CAUTION:

The internal parts of the DSC/RSC HU/CM could be damaged if 
dropped. Be careful not to drop the DSC/RSC HU/CM. Replace the 
DSC/RSC HU/CM if it is subjected to an impact.
