      Result	Proceed to
      DTC (test mode DTC) is not output	A
      DTC (test mode DTC) is output	B

   B: REPAIR SENSORS INDICATED BY OUTPUT DTCS  (See DIAGNOSTIC TROUBLE CODE CHART  )

   A: Go to Next Step 

2. CHECK YAW RATE SENSOR INSTALLATION 
   1. Check that the yaw rate sensor has been installed properly (See INSTALLATION  ).

      OK: The sensor is tightened to the specified torque. 

      The sensor is not tilted. 

   NG: INSTALL YAW RATE SENSOR CORRECTLY 

   OK: Go to Next Step 

3. PERFORM DECELERATION SENSOR ZERO POINT CALIBRATION 
   1. Perform zero point calibration of the deceleration sensor (See CALIBRATION  ).
4. RECONFIRM DTC 
   1. Clear the DTC (See DTC CHECK/CLEAR  ).
   2. Start the engine.
   3. Check if the same DTC is recorded (See DTC CHECK/CLEAR  ).

      Result	Proceed to
      DTC is output	A
      DTC is not output	B

      HINT:

      • The DTC is set if the zero point calibration has not been completed successfully.
      • End the procedure when the same DTC is not set after completion of the zero point calibration.

   B: CHECK FOR INTERMITTENT PROBLEMS (SYMPTOM SIMULATION)  (See HOW TO PROCEED WITH TROUBLESHOOTING )

   A: REPLACE VSC ACTUATOR ASSEMBLY  (See REMOVAL  )
