Diagnostic Procedure

DIAGNOSTIC PROCEDURE DESCRIPTION

STEP	INSPECTION		ACTION
1	CONFIRM DSC HU/CM AND PCM DTC Retrieve the DSC HU/CM DTC using the M-MDS (IDS). (See ON-BOARD DIAGNOSIS [DYNAMIC STABILITY CONTROL (DSC)] ). Retrieve the PCM DTC using the M-MDS (IDS), if the traction control function has problem. (See ON-BOARD DIAGNOSTIC TEST [SKYACTIV-G 2.0] ). Are any DTCs present?	Yes	Go to the applicable DTC inspection. (See ON-BOARD DIAGNOSIS [DYNAMIC STABILITY CONTROL (DSC)] ). (See DTC TABLE [SKYACTIV-G 2.0] ).
1		No	Go to the next step.
2	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.
2		No	Replace with specified tires and adjust tire air pressure.
*3	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 [2WD] ). (See REAR ABS WHEEL-SPEED SENSOR INSPECTION [AWD] ). Is the output voltage pattern normal?	Yes	Found malfunctioning part according to the "INTERMITTENT CONCERN TROUBLESHOOTING". (See PRECAUTION [DYNAMIC STABILITY CONTROL (DSC)] ).
*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. 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.
