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 out while DSC operates.

[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).

Diagnostic procedure

STEP	INSPECTION		ACTION
1	INSPECT FOR DTCs IN DSC HU/CM • Have DTCs been stored in memory?	Yes	Perform the applicable DTC inspection. (See ON-BOARD DIAGNOSIS[DYNAMIC STABILITY CONTROL (DSC)].)
1		No	Go to the next step.
2	INSPECT TIRE SIZE AND AIR PRESSURE • Inspect the tire size and air pressure. • Are the size and air pressure as specified?	Yes	Go to the next step.
2		No	Replace with the specified tires and adjust tire air pressure.
3	INSPECT ABS WHEEL-SPEED SENSOR OUTPUT VALUE • 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	Found malfunctioning part according to “INTERMITTENT CONCERN TROUBLESHOOTING”.
3		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.
