DIAGNOSTIC PROCEDURE

Step	Check	Yes	No
1 CHECK VEHICLE CONDITION.	Is the vehicle a model with VDC, which has the VDC OFF switch on the instrument panel?	Go to step 2 .	Go to step 4 .
2 CHECK DTC OF TCM.	Is DTC of AT CAN communication detected?	Perform the diagnosis according to DTC.	Go to step 3 .
3 CHECK DTC OF ABS.	Is DTC of ABS detected?	Perform the diagnosis according to DTC of ABS.	Temporary poor contact occurs. Recheck for defective parts in harness and connectors.
4 CHECK OUTPUT OF LATERAL G SENSOR USING SUBARU SELECT MONITOR. Read the value of "Lateral G Sensor" using Subaru Select Monitor.	Is the reading indicated on monitor display 2.3 to 2.7 V?	Go to step 5 .	Go to step 10 .
5 CHECK OUTPUT OF LATERAL G SENSOR USING SUBARU SELECT MONITOR. Turn the ignition switch to OFF. Remove the console box. Remove the lateral G sensor from vehicle. (Do not disconnect the connector.) Turn the ignition switch to ON. Read the value of "Lateral G Sensor" using Subaru Select Monitor.	Is the value on the display 3.3- 4.3 V with the lateral G sensor inclined 90° to right?	Go to step 6 .	Replace the lateral G sensor. Refer to LATERAL G SENSOR .
6 CHECK OUTPUT OF LATERAL G SENSOR USING SUBARU SELECT MONITOR. Read the value of "Lateral G Sensor" using Subaru Select Monitor.	Is the value on the display 0.7 - 1.7 V with the lateral G sensor inclined 90° to left?	Go to step 7 .	Replace the lateral G sensor. Refer to LATERAL G SENSOR .
7 CHECK POOR CONTACT IN CONNECTOR. Turn the ignition switch to OFF.	Is there poor contact in connector between TCM and lateral G sensor?	Repair the connector.	Go to step 8 .
8 CHECK ABSCM & H/U. Connect all connectors. Perform the Clear Memory Mode. Perform the Inspection Mode. Read the DTC.	Is the same DTC displayed?	Replace the TCM. Refer to TRANSMISSION CONTROL MODULE (TCM) .	Go to step 9 .
9 CHECK OTHER DTC DETECTION.	Is any other DTC displayed?	Perform the diagnosis according to DTC.	Temporary poor contact occurs.
10 CHECK OPEN CIRCUIT IN LATERAL G SENSOR OUTPUT HARNESS AND GROUND HARNESS. Turn the ignition switch to OFF. Disconnect the connector from TCM. Measure the resistance between TCM connector terminals. Connector & terminal (B54) No. 18 - (B55) No. 7:	Is the resistance 5.0 - 6.0 kΩ?	Go to step 11 .	Repair the harness between lateral G sensor and TCM.
11 CHECK LATERAL G SENSOR. Remove the console box. Remove the lateral G sensor from vehicle. Connect the connector to lateral G sensor. Connect the connector to ABSCM & H/U. Turn the ignition switch to ON. Measure the voltage between lateral G sensor connector terminals. Connector & terminal (B359) No. 3 (+) - No. 2 (-):	Is the voltage 2.3-2.7 V when lateral G sensor is in horizontal position?	Go to step 12 .	Replace the lateral G sensor. Refer to LATERAL G SENSOR .
12 CHECK LATERAL G SENSOR. Measure the voltage between lateral G sensor connector terminals. Connector & terminal (B359) No. 3 (+) - No. 2 (-):	Is the voltage 3.3 - 4.3 V when lateral G sensor is inclined 90° to right?	Go to step 13 .	Replace the lateral G sensor. Refer to LATERAL G SENSOR .
13 CHECK LATERAL G SENSOR. Measure the voltage between lateral G sensor connector terminals. Connector & terminal (B359) No. 3 (+) - No. 2 (-):	Is the voltage 0.7-1.7 V when lateral G sensor is inclined 90° to left?	Go to step 14 .	Replace the lateral G sensor. Refer to LATERAL G SENSOR .
14 CHECK ABSCM & H/U. Turn the ignition switch to OFF. Connect all connectors. Perform the Clear Memory Mode. Perform the Inspection Mode. Read the DTC.	Is the same DTC displayed?	Replace the TCM. Refer to TRANSMISSION CONTROL MODULE (TCM) .	Go to step 15 .
15 CHECK OTHER DTC DETECTION.	Is any other DTC displayed?	Perform the diagnosis according to DTC.	Temporary poor contact occurs.
