DETECTION CONDITION

• Malfunction detected in the DSC HU/CM solenoid valve or internal circuit by the DSC HU/CM on-board diagnostic function

FAIL-SAFE FUNCTION

• Illuminates the ABS warning light, brake system warning light, TCS/DSC indicator light, and master warning light*¹.

• Inhibits the ABS, EBD, brake assist control, TCS, Hill Launch Assist (HLA), vehicle roll prevention function*², DSC, Mazda Radar Cruise Control (MRCC)*², and Smart City Brake Support (SCBS)*² controls.

*¹: Vehicles with Smart City Brake Support (SCBS).

*²: If equipped.

POSSIBLE CAUSE

• Open or short circuit in the DSC HU/CM internal solenoid valves

• Solenoid valve malfunction

• Poor connection at connectors (female terminal)

STEP

INSPECTION

ACTION

1

• Switch the ignition off.

• Connect the M-MDS to the DLC-2.

• Switch the ignition ON (engine off).

• Access the active command mode for the solenoid valve using the M-MDS.

  (See ON-BOARD DIAGNOSIS [DYNAMIC STABILITY CONTROL (DSC)].)

• Does the solenoid valve operate?

Yes

Go to the next step.

No

Replace the DSC HU/CM, then go to the next step.

(See DSC HU/CM REMOVAL/INSTALLATION.)

2

• Clear the DTC from the memory.

  (See ON-BOARD DIAGNOSIS [DYNAMIC STABILITY CONTROL (DSC)].)

• Start the engine and drive the vehicle at 6 km/h {4 mph} or more.

• Gradually slow down and stop vehicle.

• Are the same DTCs present?

Yes

Repeat the inspection from Step 1.

If the malfunction recurs, replace the DSC HU/CM, then go to the next step.

(See DSC HU/CM REMOVAL/INSTALLATION.)

No

Go to the next step.

3

• Are any other DTCs present?

Yes

Go to the applicable DTC inspection.

(See ON-BOARD DIAGNOSIS [DYNAMIC STABILITY CONTROL (DSC)].)

No

DTC troubleshooting completed.
