Mazda 6 Service Manual: Dsc system inspection
Preparation
1. Verify that the battery is fully charged.
2. With ignition switch on, verify that the ABS warning light goes out after 2.4 seconds.
3. Turn the ignition switch off.
4. On level ground, jack up the vehicle and support it evenly on safety stands.
5. Shift the transaxle to N position.
6. Release the parking brake.
7. Rotate the wheels by hand, and inspect for brake drag.
Operation of DSC Inspection
1. Perform the Preparation.
2. Connect WDS or equivalent to the DLC-2.
3. Set up an active command modes inspection according to the combination of commands below.
Note
- When working with two people, one should press on the brake pedal, the other should attempt to rotate the wheel being inspected.
Pressure retention
Pressure reduction
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
- Extremely small leaks in the DSC HU/CM internal hydraulic system
- Unusual intermittent occurrences in the above items
