NO.10 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 DSC IS OPERATING


10	*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 DSC 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 DTCS IN DSC HU/CM • Inspect the DTC for the DSC ON-BOARD DIAGNOSTIC SYSTEM. • Have DTCs been stored in memory?	Yes	Perform the applicable DTC inspection. (See DTC Table.)
1		No	Go to the next step.
2	INSPECT TIRE SIZE AND AIR PRESSURE • Inspect the tire size and the air pressure. • Are size and air pressure as specified?	Yes	Go to the next step.
2		No	Replace with 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 Sensor Output Value Inspection.) (See Sensor Output Value Inspection.) • Is the output value normal?	Yes	Find that malfunctioning part according to "INTERMITTENT CONCERN TROUBLESHOOTING".
3		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.)
