Scheme 24

1. Perform "Preparation".
2. Connect the M-MDS to the DLC-2.
3. Set up an active command mode inspection according to the combination of commands below. Brake pressure retention WHEELS INSPECTION CHART Command name Inspected wheels LF RF LR RR V_TRC_L OFF V_TRC_R V_STB_L V_STB_R V_LF_INL ON OFF OFF OFF V_LF_OTL OFF V_LR_INL ON V_LR_OTL OFF V_RF_INL ON V_RF_OTL OFF V_RR_INL ON V_RR_OTL OFF PMP_MOTOR OFF Brake pressure reduction WHEELS INSPECTION CHART Command name Inspected wheels LF RF LR RR V_TRC_L OFF V_TRC_R V_STB_L V_STB_R V_LF_INL ON OFF OFF OFF V_LF_OTL V_LR_INL OFF ON V_LR_OTL V_RF_INL ON OFF V_RF_OTL V_RR_INL OFF ON V_RR_OTL PMP_MOTOR ON CAUTION: To protect the DSC/RSC HU/CM, the solenoid valve and the pump motor used during active command mode stay on for only 10 s or less each time they are switched on. NOTE: When working with two people, one should press on the brake pedal, and the other should attempt to rotate the wheel being inspected.
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
