Dynamic Stability Control: Other Mazda MX-5 NC рестайлинг

Preparation

1. Verify that battery is fully charged.
2. Turn the ignition switch to the ON position, and verify that the ABS warning light goes out after approx. 3 s .
3. Turn the ignition switch to the LOCK position.
4. Jack up the vehicle and support it evenly on safety stands.
5. Shift to the N position.
6. Verify that all four wheels rotate.
7. Rotate the inspected wheels by hand, and verify there is no brake drag. If there is any brake drag, perform regular brake inspection. If there is no brake drag, perform DSC HU/CM operation inspection.

Scheme 17

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 BRAKE PRESSURE RETENTION REFERENCE Command name Inspected wheels LF RF LR RR V_TRC_L Off V_TRC_R V_STB_L V_STB_R LF_INLET On Off Off Off LF_OUTLET Off LR_INLET On LR_OUTLET Off RF_INLET On RF_OUTLET Off RR_INLET On RR_OUTLET Off PMP_MOTOR Brake pressure reduction BRAKE PRESSURE RETENTION REFERENCE Command name Inspected wheels LF RF LR RR V_TRC_L Off V_TRC_R V_STB_L V_STB_R LF_INLET On Off Off Off LF_OUTLET LR_INLET Off On LR_OUTLET RF_INLET On Off RF_OUTLET RR_INLET Off On RR_OUTLET PMP_MOTOR On CAUTION: To protect the DSC 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 HU/CM operation click sound is heard, confirm that the wheel does not rotate. While brake pressure is being reduced and an DSC HU/CM operation click sound is heard, confirm that the wheel rotates. Performing the inspection above determines the following: The DSC HU/CM brake lines are normal. The DSC HU/CM hydraulic system is not significantly abnormal (including DSC HU/CM). The DSC HU/CM internal electrical parts (solenoid, motor and other parts) are normal. The DSC unit and DSC 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 HU/CM input system wiring harnesses and parts Extremely small leaks in the DSC HU/CM internal hydraulic system

DSC CONFIGURATION

1. Connect the M-MDS to the DLC-2.
2. After the vehicle is identified, select the following items from the initialization screen of the M-MDS. When using the IDS (laptop PC) Select "Module Programming". When using the PDS (Pocket PC) Select "Programming". Select "Module Programming".
3. Then, select items from the screen menu in the following order. Select "Programmable Module Installation". Select "ABS".
4. Perform the configuration according to the directions on the screen.
5. Retrieve DTCs by the M-MDS, then verify that there is no DTC present. If a DTC (s) is detected, perform the applicable DTC inspection. (See «ON-BOARD DIAGNOSTIC [DYNAMIC STABILITY CONTROL (DSC)]»(ref-430293-S20178903832011101700000) )

STEERING ANGLE SIGNAL INITIALIZATION PROCEDURE

1. Inspect the wheel alignment and inflation pressure. If there is any malfunction, adjust the applicable
2. Park the vehicle on level ground.
3. Turn the ignition switch to the LOCK position.
4. Connect the M-MDS to the DLC-2.
5. After the vehicle is identified, select the following items from the initialization screen of the M-MDS. When using the IDS (laptop PC) Select "Chassis". Select "ABS/DSC". Select "Sensor Initialization". When using the PDS (Pocket PC) Select "All Tests and Calibrations". Select "Sensor Initialization".
6. Perform the initialization procedure according to the directions on the screen.
7. Drive the vehicle forward.
8. After 5 min of driving, verify that the DSC system is normal.

COMBINED SENSOR INITIALIZATION PROCEDURE

1. Inspect the wheel alignment and inflation pressure. If there is any malfunction, adjust the applicable part.
2. Park the vehicle on level ground.
3. Turn the ignition switch to the LOCK position.
4. Connect the M-MDS to the DLC-2.
5. After the vehicle is identified, select the following items from the initialization screen of the M-MDS. When using the IDS (laptop PC) Select "Chassis". Select "ABS/DSC". Select "Sensor Initialization". When using the PDS (Pocket PC) Select "All Tests and Calibrations". Select "Sensor Initialization".
6. Perform the initialization procedure according to the directions on the screen.
7. Drive the vehicle forward.
8. After 5 min of driving, verify that the DSC system is normal.

STEERING ANGLE SENSOR INITIALIZATION PROCEDURE

Note. The initialization value of the steering angle sensor is stored using the battery power supply. Therefore, the battery power supply of the steering angle sensor is cut and the stored initialization value is cleared when any of the following items are performed. Negative battery cable disconnection Steering angle sensor connector disconnection Fuse (ROOM 15A) removal Wiring harness disconnection between battery and steering angle sensor connector

1. Inspect the wheel alignment, inflation pressure, and the installation condition of the steering wheel. If there is any malfunction, adjust the applicable part.
2. Connect the negative battery cable.
3. Turn the ignition switch to the ON position.
4. Confirm that the DSC indicator light illuminates and that the DSC OFF light flashes.
5. Turn the steering wheel to full right lock, then turn it to full left lock.
6. Confirm that the DSC OFF light goes out.
7. Turn the ignition switch to the LOCK position.
8. Turn the ignition switch to the ON position again, and confirm that the DSC indicator light goes out. If the DSC indicator light does not go out, disconnect the negative battery cable, and perform the procedure again starting from step 2 shown above.
9. Drive the vehicle for approx. 10 min , and confirm that the ABS warning and DSC indicator lights do not illuminate.

Scheme 18
