Diagnostic Procedure with Diagnostic Trouble Code (DTC) > DTC B1507 EXTERNAL AIR TEMPERATURE OPEN/SHORT-CIRCUIT DETECTION">Go to Step 2.

Diagnostic Procedure with Diagnostic Trouble Code (DTC) > DTC B1507 EXTERNAL AIR TEMPERATURE OPEN/SHORT-CIRCUIT DETECTION">Go to Step 6.

2.CHECK CURRENT DATA.

Using the Subaru Select Monitor, display «Ambient air temperature» from «Data monitor». Read Current Data">

Is data displayed?

System is normal.

Diagnostic Procedure with Diagnostic Trouble Code (DTC) > DTC B1507 EXTERNAL AIR TEMPERATURE OPEN/SHORT-CIRCUIT DETECTION">Go to Step 3.

3.CHECK HARNESS (OPEN CIRCUIT).

1) Turn the ignition switch to OFF.

2) Disconnect the combination meter connector and ambient sensor connector.

3) Using the tester, measure the resistance between terminals.

Connector & terminal

(i10) No. 36 — (F78) No. 2:

(i10) No. 27 — (F78) No. 1:

Is the resistance 10 ? or less?

Diagnostic Procedure with Diagnostic Trouble Code (DTC) > DTC B1507 EXTERNAL AIR TEMPERATURE OPEN/SHORT-CIRCUIT DETECTION">Go to Step 4.

Repair the open circuit of harness or replace harness.

4.CHECK HARNESS (GROUND SHORT CIRCUIT).

Using the tester, measure the resistance between terminals.

Connector & terminal

(i10) No. 36 — Chassis ground:

(i10) No. 27 — Chassis ground:

Is the resistance 10 ? or less?

Repair the short circuit of harness or replace harness.

Diagnostic Procedure with Diagnostic Trouble Code (DTC) > DTC B1507 EXTERNAL AIR TEMPERATURE OPEN/SHORT-CIRCUIT DETECTION">Go to Step 5.

5.CHECK AMBIENT SENSOR.

Perform the inspection of ambient sensor unit. Ambient Sensor">

Is the sensor normal?

Diagnostic Procedure with Diagnostic Trouble Code (DTC) > DTC B1507 EXTERNAL AIR TEMPERATURE OPEN/SHORT-CIRCUIT DETECTION">Go to Step 6.

Replace the sensor. Ambient Sensor">

6.CHECK CONNECTOR.

1) Turn the ignition switch to OFF.

2) Disconnect connectors.

Is there poor contact of connector?

Repair or replace the poor contact of connector.

Even if DTC is displayed, 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.
