DIAGNOSTIC PROCEDURE CHART

Step	Check	Yes	No
1 CHECK YAW RATE & G SENSOR INSTALLATION.	Is the yaw rate & G sensor installation bolt tightened to 7.5 N.m (0.76 kgf-m, 5.5 ft-lb)?	Go to step 2.	Tighten the yaw rate & G sensor attachment bolt.
2 CHECK OUTPUT OF LATERAL G SENSOR WITH SUBARU SELECT MONITOR. Park the vehicle on a level surface. Select {Current Data Display & Save} in Subaru Select Monitor. Read the lateral G sensor output displayed on screen.	Is the indicated reading on the monitor display -1.5 - 1.5 m/s² ?	Go to step 3.	Replace the yaw rate & G sensor. < Ref. to YAW RATE AND G SENSOR . >
3 CHECK OUTPUT OF LATERAL G SENSOR WITH SUBARU SELECT MONITOR. Turn the ignition switch to OFF. Remove the yaw rate & G sensor from vehicle. Turn the ignition switch to ON, and select the {Current Data Display & Save} in Subaru Select Monitor. Read the lateral G sensor output displayed on screen.	When the yaw rate & G sensor is inclined 90° to the right, is the indicated value 6.8 - 12.8 m/s² ?	Go to step 4.	Replace the yaw rate & G sensor. < Ref. to YAW RATE AND G SENSOR . >
4 CHECK LATERAL G SENSOR WITH SUBARU SELECT MONITOR. Read the lateral G sensor output displayed on screen.	When the yaw rate & G sensor is inclined 90° to the left, is the indicated value -6.8 - -12.8 m/s² ?	Go to step 5.	Replace the yaw rate & G sensor. < Ref. to YAW RATE AND G SENSOR . >
5 CHECK POOR CONTACT OF CONNECTORS. Turn the ignition switch to OFF.	Is there poor contact of connector between VDCCM&H/U and yaw rate & G sensor?	Repair the connector.	Go to step 6 .
6 CHECK VDCCM&H/U. 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?	Replace the VDCCM only. < Ref. to REPLACEMENT , VDC Control Module and Hydraulic Control Unit (VDCCM&H/U). >	Go to step 7 .
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.
