1. CHECK SWITCH UNIT Measure the resistance between harness connector terminals of the X mode switch. | Terminal No. | Standard | OFF (when measured without operating the switch) | No. 1 — No. 4 | 1 M- or more | ON (when measured with the switch held down) | Less than 1 - |
2. CHECK X MODE SYSTEM DIAGNOSIS: It does not switch to X mode. CAUTION: Note that the system performs the following controls when switching to X mode. (1) When the malfunction indicator light comes on while the engine is running, it cannot switch to X mode. (2) If there is a possible engine coolant or engine oil temperature overheat condition, it will not be possible to switch to X mode. (3) If the ignition switch is in ON position before starting engine, switching to X mode is not available. 3. PRESSING X MODE SWITCH DOES NOT CHANGE THE X MODE DISPLAY IN THE COMBINATION METER AND MODE DOES NOT SWITCH TO X MODE WIRING DIAGRAM: CVT Control System > WIRING DIAGRAM STEP | CHECK | YES | NO | 1.CHECK X MODE SWITCH. 1) Turn the ignition switch to OFF. 2) Disconnect the connector from the combination meter. 3) Measure the resistance when the X mode switch is operated. Connector & terminal (i10) No. 37 — Chassis ground: | Does the resistance change as below- 1 M- or more > less than 10 -
| X MODE Switch > INSPECTION | X MODE Switch > INSPECTION | 2.CHECK HARNESS BETWEEN COMBINATION METER AND X MODE SWITCH CONNECTOR. Measure the resistance of harness between combination meter and X mode switch connector. Connector & terminal (i10) No. 37 — (i70) No. 1: | Is the resistance less than 10 -- | X MODE Switch > INSPECTION | Repair the harness and connector. NOTE: In this case, repair the following item: • Open circuit in harness between combination meter and X mode switch connector • Poor contact of connector | 3.CHECK HARNESS BETWEEN COMBINATION METER AND X MODE SWITCH CONNECTOR. Measure the resistance of harness between X mode switch connector and chassis ground. Connector & terminal (i70) No. 1 — Chassis ground: | Is the resistance 1 M- or more- | X MODE Switch > INSPECTION | Repair the short circuit to ground in harness between combination meter and X mode switch connector. | 4.CHECK HARNESS BETWEEN X MODE SWITCH CONNECTOR AND CHASSIS GROUND. Measure the resistance between combination meter and chassis ground. Connector & terminal (i70) No. 4 — Chassis ground: | Is the resistance less than 10 -- | Repair the poor contact of X mode switch connector. Replace the X mode switch if faulty. X MODE Switch X MODE Switch | Repair the harness and connector. NOTE: In this case, repair the following item: • Open circuit in harness between X mode switch connector and chassis ground • Poor contact of joint connector | 5.RECHECK FAULT. 1) Connect all connectors. | | Repair the poor contact of combination meter. Replace the meter case assembly if defective. | The circuit has returned to a normal condition at this time. Reproduce the failure, and then perform the diagnosis again. NOTE: In this case, temporary poor contact of connector, temporary open or short circuit of harness may be the cause. |
4. WHEN SWITCHED TO X MODE, “X” MODE DISPLAY IN COMBINATION METER FLASHES IN AFTER APPROX. 5 SECONDS STEP | CHECK | YES | NO | | | Check the appropriate DTC using the “List of Diagnostic Trouble Code (DTC)” concerning the respective units. | X MODE Switch > INSPECTION | 2.CHECK COMBINATION METER AND CLOCK DISPLAY. Check for abnormal indication other than “X” blinking. Examples: • Malfunction indicator light illuminates. • Fuel economy display area is not ON. NOTE: The system enters into fail mode with ignition ON and engine OFF. | Is there any abnormal indication other than “X” blinking- | For the diagnostic procedure, refer to LAN section. Basic Diagnostic Procedure | X MODE Switch > INSPECTION | 3.CHECK ECM AND COMBINATION METER. | Is the part number of ECM and combination meter correct- | Replace the meter case assembly. Combination Meter | Replace ECM or meter case assembly with the one with the correct part number. Engine Control Module (ECM) Combination Meter |
5. WHEN SWITCHED TO X MODE, “X” MODE DISPLAY IN COMBINATION METER FLASHES NOTE: In this case, there may be a fault other than in X mode system. STEP | CHECK | YES | NO | 1.CHECK MALFUNCTION INDICATOR LIGHT. 2) Check if malfunction indicator light illuminates. | Does the malfunction indicator light illuminate- | Read the DTC using Subaru Select Monitor and check the indicated DTC. Read Diagnostic Trouble Code (DTC) | X MODE Switch > INSPECTION | 2.CHECK COOLANT TEMPERATURE WARNING LIGHT. 1) Turn the ignition switch to ON. 2) Check the coolant temperature warning light. | Does it indicate overheating- | Inspect for the cause of overheating and repair. | X MODE Switch > INSPECTION | 3.CHECK ENGINE OIL TEMPERATURE. 1) Turn the ignition switch to ON. 2) Check the value of «Oil Temperature» using Subaru Select Monitor. NOTE: For detailed operation procedures, refer to “Current Data Display For Engine”. Subaru Select Monitor | Is the value of «Oil Temperature» 117°C (243°F) or more- | Inspect and repair the cause of engine oil temperature rise. NOTE: Ask the customer whether the vehicle has experienced a long drive in low gear or towing of heavy load. If not, drive the vehicle again after the engine oil temperature lowers, and check if the engine oil temperature rises. | X MODE Switch > INSPECTION | 4.CHECK COMBINATION METER INDICATION. 3) Check X mode display in the combination meter. | Does “X” mode indication in the combination meter blink- | Replace the meter case assembly. Combination Meter | Perform test operation and check the malfunction indicator light, engine coolant temperature warning light, and engine oil temperature. If they are normal, finish the diagnosis. |
