| STEP | CHECK | YES | NO |
1.CHECK FUSE.
1) Turn the ignition switch to OFF.
2) Check the fuse for radar sensor LH. Relay and Fuse">
Is it normal?
Subaru Select Monitor > INSPECTION">Go to Step 2.
Replace the fuse. If the replaced fuse has blown out immediately, repair the short circuit to ground in harness between fuse and radar sensor LH.
2.CHECK HARNESS (OPEN CIRCUIT).
1) Disconnect the radar sensor LH connector.
2) Turn the ignition switch to ON.
3) Using a tester, measure the voltage between radar sensor LH connector (harness side) and chassis ground.
Connector & terminal
(R25) No. 5 (+) — Chassis ground (−):
Is the voltage 10 V or more?
Subaru Select Monitor > INSPECTION">Go to Step 3.
Repair the open circuit of harness between fuse and radar sensor LH connector.
3.CHECK HARNESS (OPEN CIRCUIT).
1) Turn the ignition switch to OFF.
2) Using a tester, measure the resistance between radar sensor LH connector (harness side) and chassis ground.
Connector & terminal
(R25) No. 10 — Chassis ground:
Is the resistance less than 1 ??
Subaru Select Monitor > INSPECTION">Go to Step 4.
Repair the open circuit in harness between radar sensor and chassis ground.
4.CHECK LAN SYSTEM.
1) Connect the radar sensor LH connector.
2) Inspect LAN system. Basic Diagnostic Procedure">
Is it normal?
Subaru Select Monitor > INSPECTION">Go to Step 5.
Perform the inspection according to the diagnosis for LAN system.
5.CHECK RADAR SENSOR.
Communicate with the radar sensor.
Is communication possible?
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.
Replace the radar sensor LH. Radar Sensor">
