Subaru Legacy Service Manual: Inspection

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

STEPCHECKYESNO

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.

2) Switch to X mode.

Is there any fault-

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

STEPCHECKYESNO

1.CHECK DTC.

Is DTC displayed-

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.

STEPCHECKYESNO

1.CHECK MALFUNCTION INDICATOR LIGHT.

1) Start the engine.

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.

1) Start the engine.

2) Switch to X mode.

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.
