NO. 5 ABS OR TCS*1 OPERATES FREQUENTLY/TCS DOES NOT WORK CORRECTLY*1 (DYNAMIC STABILITY CONTROL) DIAGNOSTIC PROCEDURE

Step	Inspection	Results	Action
1	CONFIRM DSC HU/Control Module AND PCM DTC Retrieve the DSC HU/Control Module DTC using the M-MDS. (See DTC INSPECTION .) Retrieve the PCM DTC using the M-MDS, if the traction control function has problem. (See DTC INSPECTION .) Are any DTCs present?	Yes	Go to the applicable DTC inspection. (See DTC TABLE [PCM (VIN Y)] .) (See DTC TABLE [DSC HU/Control Module (US)] .) (See DTC TABLE [PCM (VINs 7, L, M) (US)] .)
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? (See WHEEL AND TIRE SPECIFICATION (US) .)	Yes	Go to the next step.
2		No	Replace with specified tires and adjust tire air pressure, and perform the repair completion verification. (See TIRE PRESSURE ADJUSTMENT (US) .)
3	INSPECT ABS WHEEL-SPEED SENSOR Inspect 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 ABS wheel-speed sensor normal?	Yes	Found malfunctioning part according to the "INTERMITTENT CONCERN TROUBLESHOOTING". (See PRECAUTION .)
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. (See FRONT ABS WHEEL-SPEED SENSOR REMOVAL/INSTALLATION .) (See REAR ABS WHEEL-SPEED SENSOR REMOVAL/INSTALLATION .) Perform the repair completion verification.
Repair completion verification	VERIFY THAT MALFUNCTION SYMPTOMS DO NOT RECUR AFTER REPAIR Install/connect the part removed/disconnected during the troubleshooting procedure. Has the malfunction symptom been eliminated?	Yes	Complete the symptom troubleshooting. Explain to the customer what has been repaired.
Repair completion verification		No	Refer to the controller area network (CAN) malfunction diagnosis flow to inspect for a CAN communication error. (See CONTROLLER AREA NETWORK (CAN) MALFUNCTION DIAGNOSIS FLOW (US) .) If the CAN communication is normal, perform the diagnosis from Step 1.
