POSSIBLE CAUSE	• DSC HU/CM detected malfunction (input and output device malfunction). • There is a difference in size or air pressure between front or rear tires. • Poor installation with SAS control module (yaw rate sensor, low-G (XY) sensor) and/or steering angle sensor (If any of the above sensors are poorly installed, DSC may operate intermittently.) • When replacing DSC HU/CM or steering angle sensor initialization is not performed (If initialization is not performed correctly, DSC may not work correctly). • Incorrect ABS wheel speed sensor is inputted to DSC HU/CM.

DSC does not work correctly

^*2: DSC indicator light goes on and off while DSC operates

POSSIBLE CAUSE

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

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

• Poor installation with SAS control module (yaw rate sensor, low-G (XY) sensor) and/or steering angle sensor (If any of the above sensors are poorly installed, DSC may operate intermittently.)

• When replacing DSC HU/CM or steering angle sensor initialization is not performed (If initialization is not performed correctly, DSC may not work correctly).

• Incorrect ABS wheel speed sensor is inputted to DSC HU/CM.

STEP	INSPECTION	ACTION
1	CONFIRM DSC HU/CM DTC • Retrieve the DSC HU/CM DTC using the M-MDS. (See ON-BOARD DIAGNOSIS [DYNAMIC STABILITY CONTROL (DSC)].) • Are any DTCs present?	Yes	Go to the applicable DTC inspection. (See ON-BOARD DIAGNOSIS [DYNAMIC STABILITY CONTROL (DSC)].)
No	Go to the next step.
2	VERIFY THAT EACH SENSOR IS INSTALLED • Verify that each sensor is installed. • Are SAS control module (yaw rate sensor, low-G (XY) sensor) and steering angle sensor securely installed?	Yes	Go to the next step.
No	Install the malfunctioning sensor securely.
3	VERIFY THAT EACH SENSOR IS INITIALIZED • Verify that each sensor is initialized. • Did each sensor initialize after replacement of DTC HU/CM or steering angle sensor?	Yes	Go to the next step.
No	Perform the initialization procedure. (See DSC SENSOR INITIALIZATION PROCEDURE.)
4	INSPECT TIRE SIZE AND AIR PRESSURE • Inspect tire size and air pressure. • Tire size and air pressure as specified?	Yes	Go to the next step.
No	Replace with specified tires and adjust tire air pressure.
5^*	INSPECT ABS WHEEL-SPEED SENSOR OUTPUT PULSE • Perform the Voltage Pattern Inspection for each ABS wheel-speed sensor. (See FRONT ABS WHEEL-SPEED SENSOR INSPECTION.) (See REAR ABS WHEEL-SPEED SENSOR INSPECTION.) • Is the output voltage pattern normal?	Yes	Found malfunctioning part according to the “INTERMITTENT CONCERN TROUBLESHOOTING”. (See PRECAUTION [DYNAMIC STABILITY CONTROL (DSC)].)
No	ABS wheel-speed sensor installation inspection: • Inspect the ABS wheel-speed sensor for looseness and confirm it is securely adhered. ABS sensor rotor installation inspection: • Inspect the ABS sensor rotor for poor installation. Repair or replace any malfunctioning parts according to the inspection result.

STEP

INSPECTION

ACTION

CONFIRM DSC HU/CM DTC

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

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

• Are any DTCs present?

Yes

Go to the applicable DTC inspection.

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

Go to the next step.

VERIFY THAT EACH SENSOR IS INSTALLED

• Verify that each sensor is installed.

• Are SAS control module (yaw rate sensor, low-G (XY) sensor) and steering angle sensor securely installed?

Yes

Go to the next step.

Install the malfunctioning sensor securely.

VERIFY THAT EACH SENSOR IS INITIALIZED

• Verify that each sensor is initialized.

• Did each sensor initialize after replacement of DTC HU/CM or steering angle sensor?

Yes

Go to the next step.

Perform the initialization procedure.

(See DSC SENSOR INITIALIZATION PROCEDURE.)

INSPECT TIRE SIZE AND AIR PRESSURE

• Inspect tire size and air pressure.

• Tire size and air pressure as specified?

Yes

Go to the next step.

Replace with specified tires and adjust tire air pressure.

5^*

INSPECT ABS WHEEL-SPEED SENSOR OUTPUT PULSE

• Perform the Voltage Pattern Inspection for each ABS wheel-speed sensor.

(See FRONT ABS WHEEL-SPEED SENSOR INSPECTION.)

(See REAR ABS WHEEL-SPEED SENSOR INSPECTION.)

• Is the output voltage pattern normal?

Yes

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

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

ABS wheel-speed sensor installation inspection:

• Inspect the ABS wheel-speed sensor for looseness and confirm it is securely adhered.

ABS sensor rotor installation inspection:

• Inspect the ABS sensor rotor for poor installation.

Repair or replace any malfunctioning parts according to the inspection result.

• When performing an asterisked (*) troubleshooting inspection, shake the wiring harness and connectors while doing the inspection to discover whether poor contact points are the cause of any intermittent malfunctions. If there is a problem, check to make sure connectors, terminals and wiring harness are connected correctly and undamaged.
