WIRING DIAGRAM:
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.
|
Is the reading indicated on monitor display 2.3 to 2.7 V when lateral G sensor is level? | Go to step 5. | Go to step 8. |
| 5 CHECK POOR CONTACT OF CONNECTOR. | Is there poor contact in connector between TCM and lateral G sensor? | Repair the connector. | Go to step 6. |
6 CHECK ABSCM&H/U.
|
Is the same DTC displayed? | Replace the TCM. < Ref. to TRANSMISSION CONTROL MODULE (TCM) . > | Go to step 7. |
| 7 CHECK OTHER DTC DETECTION. | Is any other DTC displayed? | Perform the diagnosis according to DTC. | Temporary poor contact occurs. |
| 8 CHECK INFORMATION STORED IN FREEZE FRAME DATA. Read the lateral G sensor output on Subaru Select Monitor. |
Is the reading on monitor display more than 4.65 V? | Go to step 9. | Go to step 15 . |
9 CHECK OPEN CIRCUIT IN LATERAL G SENSOR OUTPUT HARNESS AND GROUND HARNESS.
|
Is the resistance between 4.3 and 4.9 kΩ? | Go to step 10 . | Repair the harness connector between the lateral G sensor and ABSCM&H/U. |
10 CHECK BATTERY SHORT OF HARNESS.
|
Is the voltage less than 1 V? | Go to step 11 . | Repair the harness between lateral G sensor and TCM. |
11 CHECK BATTERY SHORT OF HARNESS.
|
Is the voltage less than 1 V? | Go to step 12 . | Repair the harness between lateral G sensor and TCM. |
| 12 CHECK POOR CONTACT OF CONNECTOR. | Is there poor contact in connector between TCM and lateral G sensor? | Repair the connector. | Go to step 13 . |
13 CHECK TCM.
|
Is the same DTC displayed? | Replace the TCM. < Ref. to TRANSMISSION CONTROL MODULE (TCM) . > | Go to step 14 . |
| 14 CHECK OTHER DTC DETECTION. | Is any other DTC displayed? | Perform the diagnosis according to DTC. | Temporary poor contact occurs. |
15 CHECK LATERAL G SENSOR INPUT VOLTAGE.
|
Is the voltage 4.75 - 5.25 V? | Go to step 16 . | Repair the harness between lateral G sensor and TCM. |
16 CHECK OPEN CIRCUIT IN LATERAL G SENSOR OUTPUT HARNESS AND GROUND HARNESS.
|
Is the resistance between 5.0 and 5.6 kΩ? | Go to step 17 . | Repair the harness between lateral G sensor and TCM. |
17 CHECK LATERAL G SENSOR.
|
Is the voltage 2.3 - 2.7 V when lateral G sensor is in horizontal position? | Go to step 18 . | Replace the lateral G sensor. < Ref. to LATERAL G SENSOR . > |
| 18 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 19 . | Replace the lateral G sensor. < Ref. to LATERAL G SENSOR . > |
| 19 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 20 . | Replace the lateral G sensor. < Ref. to LATERAL G SENSOR . > |
| 20 CHECK POOR CONTACT OF 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 21 . |
21 CHECK ABSCM&H/U.
|
Is the same DTC displayed? | Replace the TCM. < Ref. to TRANSMISSION CONTROL MODULE (TCM) . > | Go to step 22 . |
| 22 CHECK OTHER DTC DETECTION. | Is any other DTC displayed? | Perform the diagnosis according to DTC. | Temporary poor contact occurs. |
