DSC^*2 operates frequently

DSC does not work correctly

^*2: TCS/DSC indicator light turns on and off while DSC operates

POSSIBLE CAUSE

• DSC HU/CM detected malfunction. (Input and output device malfunction)

• Poor installation with SAS control module (yaw rate sensor, low-G sensor) (If SAS control module is poorly installed, DSC may operate intermittently.)

• There is a difference in condition or air pressure between front or rear tires.

• When replacing DSC HU/CM and SAS control module, initialization is not performed. (If initialization is not performed correctly, DSC may not work correctly.)

STEP

INSPECTION

ACTION

1

• Retrieve the DSC HU/CM DTC using the M-MDS.

  (See DTC INSPECTION [DSC HU/CM].)

• Are any DTCs present?

Yes

Go to the applicable DTC inspection.

(See DTC INSPECTION [DSC HU/CM].)

No

Go to the next step.

2

• Verify that each sensor is initialized.

• Has the initialization for the DSC HU/CM been performed after replacing the DSC HU/CM and the SAS control module?

Yes

Inspect the tire pressure and condition.

If the tire pressure is incorrect:

• Adjust the tire pressure to the specification

If the tires are worn:

• Replace the tires.

If the tire pressure and condition is normal:

• Found malfunctioning part according to the “INTERMITTENT CONCERN TROUBLESHOOTING”.

  (See PRECAUTION [DYNAMIC STABILITY CONTROL (DSC)].)

No

Perform the initialization procedure.

(See DSC RELATED PARTS SENSOR INITIALIZATION PROCEDURE.)
