DIAGNOSTIC PROCEDURE CHART

Step	Check	Yes	No
1 CHECK POWER SUPPLY FOR YAW RATE & G SENSOR. Turn the ignition switch to OFF. Disconnect the connector from yaw rate & G sensor. Turn the ignition switch to ON. Measure the voltage between yaw rate & G sensor and chassis ground. Connector & terminal (B230) No. 1 (+) - Chassis ground (-):	Is the voltage 10 - 15 V?	Go to step 2.	Repair the yaw rate & G sensor power supply circuit.
2 CHECK YAW RATE & G SENSOR GROUND CIRCUIT. Measure the resistance between yaw rate & G sensor and chassis ground. Connector & terminal (B230) No. 4 - Chassis ground:	Is the resistance less than 10 Ω?	Go to step 3.	Repair the yaw rate & G sensor ground circuit.
3 CHECK YAW RATE & G SENSOR HARNESS. Disconnect the connector from the VDCCM&H/U. Measure the resistance between VDCCM&H/U and yaw rate & G sensor. Connector & terminal (B230) No. 3 - (B310) No. 10: (B230) No. 2 - (B310) No. 35:	Is the resistance less than 1 Ω?	Go to step 4.	Repair the harness between yaw rate & G sensor and VDCCM&H/U.
4 CHECK GROUND SHORT CIRCUIT IN YAW RATE & G SENSOR HARNESS. Measure the resistance between yaw rate & G sensor and chassis ground. Connector & terminal (B230) No. 2 - Chassis ground: (B230) No. 3 - Chassis ground:	Is the resistance 1 MΩ or more?	Go to step 5.	Repair the harness between yaw rate & G sensor and VDCCM&H/U.
5 CHECK YAW RATE & G SENSOR. Turn the ignition switch to OFF. Connect all connectors. Clear the memory. < Ref. to CLEAR MEMORY MODE . > Perform the Inspection Mode. < Ref. to INSPECTION MODE . > Read the DTC.	Is the same DTC displayed?	Go to step 6.	Go to step 7 .
6 CHECK YAW RATE & G SENSOR. Turn the ignition switch to OFF. Replace the yaw rate & G sensor. < Ref. to YAW RATE AND G SENSOR . > Clear the memory. < Ref. to CLEAR MEMORY MODE . > Perform the Inspection Mode. < Ref. to INSPECTION MODE . > Read the DTC.	Is the same DTC displayed?	Replace the VDCCM only. < Ref. to REPLACEMENT , VDC Control Module and Hydraulic Control Unit (VDCCM&H/U). >	Go to step 8 .
7 CHECK OTHER DTC DETECTION.	Is any other DTC displayed?	Perform the diagnosis according to DTC. < Ref. to LIST OF DIAGNOSTIC TROUBLE CODE (DTC) . >	Temporary poor contact occurs.
8 CHECK OTHER DTC DETECTION.	Is any other DTC displayed?	Perform the diagnosis according to DTC. < Ref. to LIST OF DIAGNOSTIC TROUBLE CODE (DTC) . >	Malfunction is found in original yaw rate & G sensor.
