Reverse Automatic Braking(DIAGNOSTICS) > Inspection Mode
PROCEDURE

It is possible to diagnose the DTC by performing the indicated inspection mode. After correcting the DTC, perform the inspection mode and make sure that the function is resumed correctly and the DTC is recorded.

1.

Turn the ignition switch to ON, and wait for 6 seconds or more. (∗1)

2.

Confirm that the RAB warning light (RAB malfunction indicator light) of MID in the combination meter is off.

3.

Read the DTC and check that the DTC is not displayed. (∗2)

∗1: Even with normal condition, “RAB warning light (RAB OFF indicator light)” illuminates for 6 seconds after turning the ignition switch to ON, and then goes off after 6 seconds.

∗2: Perform all DTC diagnosis within 3 seconds after the ignition switch is turned to ON. It is not necessary to shift the gear in the R range to operate the function.

Reverse Automatic Braking(DIAGNOSTICS) > Warning Light Illumination Pattern
INSPECTION

- When the Reverse Automatic Braking is error

  “RAB” illuminates in MID in the combination meter.

- When the Reverse Automatic Braking is stopped temporarily

  “RAB OFF” illuminates in MID in the combination meter.

Even with normal condition, “RAB warning light (RAB OFF indicator light)” illuminates for 6 seconds after turning the ignition switch to ON, and then goes off after 6 seconds.

Replace the fuse. If the replaced fuse has blown out immediately, repair the short circuit to ground in harness between fuse — RAB CM.

2. CHECK POWER SUPPLY CIRCUIT (OPEN).
1.

Disconnect the RAB CM connector.

2.

Turn the ignition switch to ON.

3.

Using a tester, measure the voltage between the RAB CM connector and chassis ground.

Connector & terminal

(R361) No. 1 (+) — Chassis ground (−):

(R361) No. 13 (+) — Chassis ground (−):

Is the voltage 10 V or more?

3

Repair the open circuit in the harness between fuse and RAB CM connector.

3. CHECK GROUND CIRCUIT (OPEN).
1.

Turn the ignition switch to OFF.

2.

Using a tester, measure the resistance between the RAB CM connector and chassis ground.

Connector & terminal

(R361) No. 2 — Chassis ground:

Is the resistance less than 1 Ω?

4

Repair the open circuit of harness between RAB CM connector and chassis ground.

4. CHECK LAN SYSTEM.
1.

Connect the RAB CM connector.

2.

Perform the diagnosis for LAN system. LAN SYSTEM (DIAGNOSTICS)>Basic Diagnostic Procedure>PROCEDURE

Is the check result OK?

5

Perform the inspection according to the diagnosis for LAN system.

5. CHECK SUBARU SELECT MONITOR.

Connect the Subaru Select Monitor to another vehicle.

Is the communication possible with the vehicle?

6

Replace or repair the Subaru Select Monitor.

6. CHECK RAB CM.
1.

Turn the ignition switch to ON.

2.

Communicate with [Reverse Automatic Braking] using the select monitor.

Is communication possible?

- The circuit has returned to a normal condition at this time. Reproduce the failure, and then perform the diagnosis again.

  In this case, temporary poor contact of connector, temporary open or short circuit of harness may be the cause.

Replace the RAB CM. Reverse Automatic Braking>Reverse Automatic Braking CM
