C0061:54, C0062:54, C0063:54

DSC HU/CM system (unperformed initialization procedure)

DETECTION CONDITION

• C0061:54

• DSC HU/CM detects that the initialization procedure has not been performed. (Lateral acceleration sensor)

• C0062:54

• DSC HU/CM detects that the initialization procedure has not been performed. (Longitudinal acceleration sensor)

• C0063:54

• DSC HU/CM detects that the initialization procedure has not been performed. (Yaw rate sensor)

FAIL-SAFE FUNCTION

• C0061:54

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

• Tire pressure monitoring system warning light illuminates after flashes.

• Inhibits the ABS, brake assist, TCS, DSC, Mazda Radar Cruise Control (MRCC)*², Smart City Brake Support (SCBS)*², and TPMS controls.

• C0062:54

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

• Inhibits the ABS, brake assist, 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.

• C0063:54

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

• Tire pressure monitoring system warning light illuminates after flashes.

• Inhibits the TCS, DSC, Mazda Radar Cruise Control (MRCC)*², Smart City Brake Support (SCBS)*², and TPMS controls.

STEP

INSPECTION

ACTION

1

• Was the DSC related parts sensor initialization procedure performed?

Yes

Go to the next step.

No

Perform the DSC related parts sensor initialization procedure, then go to Step 3.

(See DSC RELATED PARTS SENSOR INITIALIZATION PROCEDURE.)

2

• Switch the ignition off.

• Using the M-MDS, perform the DTC inspection for the SAS control module.

  (See DTC INSPECTION [STANDARD DEPLOYMENT CONTROL SYSTEM].)

  (See DTC INSPECTION [TWO-STEP DEPLOYMENT CONTROL SYSTEM].)

• Are any DTCs detected?

Yes

Go to applicable DTC inspection.

(See DTC TABLE [STANDARD DEPLOYMENT CONTROL SYSTEM].)

(See DTC TABLE [TWO-STEP DEPLOYMENT CONTROL SYSTEM].)

No

Go to the next step.

3

• Clear the DTCs from the memory.

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

• 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.

4

• Are any other DTCs output?

Yes

Go to the applicable DTC inspection.

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

No

DTC troubleshooting completed.
