Note
• To protect the DSC HU/CM, the solenoid valve used for simulations and the ABS motor stay on for 10
seconds each time they are switched on.
4. Send the command while pressing on the brake pedal and attempting to rotate the wheel being inspected.
5. When pressure is being maintained, and a click sound indicating the solenoid is operating comes from the DSC
HU/CM, confirm that the wheel does not rotate. When pressure is being reduced, and a click sound indicating
the solenoid is operating comes from DSC HU/CM, confirm that the wheel rotates, even though the brake pedal
is being depressed.
• Performing the inspections above determines the following.
— The DSC HU/CM brake lines are normal
— The DSC HU/CM hydraulic system is not significantly abnormal
— The DSC HU/CM wiring is normal
— Output system harness in DSC HU/CM (solenoid, relay) are normal
• However, the following items cannot be checked.
— The DSC HU/CM input system harness and parts
— Etremely small leaks in the DSC HU/CM internal hydraulic system
— Unusual intermittent occurrences in the above items
