ABS or TCS (*1) operates frequently./TCS does not work correctly.

(*1): DSC system function contains traction control function; DSC indicator light goes on and off while TCS is operating.

[TROUBLESHOOTING HINTS]

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

• Incorrect ABS wheel-speed signal is input to DSC HU/CM

• There is a malfunction in the engine control system (TCS malfunction)

STEP

INSPECTION

ACTION

1

• Inspect the DTC for the DSC ON-BOARD DIAGNOSTIC SYSTEM.

• Have DTCs been stored in memory?

Yes

Perform the applicable DTC inspection.

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

No

Go to the next step.

2

• Inspect the tire size and the air pressure.

• Are size and air pressure as specified?

Yes

Go to the next step.

No

Replace with specified tires and adjust tire air pressure.

3

• Inspect the output value from the ABS wheel-speed sensor.

  (See FRONT ABS WHEEL-SPEED SENSOR INSPECTION.)

  (See REAR ABS WHEEL-SPEED SENSOR INSPECTION.)

• Is the output value normal?

Yes

Find that malfunctioning part according to “INTERMITTENT CONCERN TROUBLESHOOTING”.

No

• ABS wheel-speed sensor installation inspection:

  Inspect the sensor for looseness and verify that it is securely installed.

• Sensor rotor installation inspection:

  Inspect the sensor rotor for poor installation and chipping of sensor rotor teeth. (If sensor rotor is installed poorly, it may cause output of abnormal wave form at high speed.)
