RADAR ASSY B&&S High Voltage
(more than 16V)

This failure occurs if the voltage
applied to the rear side radar stays
at 16 V or higher for about 5 sec.

When the power supply becomes lower
than 16 V, the triggered indication is reset.

B2327

RADAR ASSY B&&S internal
failure (internal electric circuit)

This failure occurs if the rear side
radar internal failure is detected.

When this failure occurs, basically replace
the radar with a new one.

B2328

RADAR ASSY B&&S internal
failure (RADAR misalignment)

This failure occurs if eccentricity
is detected in the rear side radar
axis.

Adjust the axis of the radar.

This failure occurs if the axis

B2340

RADAR ASSY B&&S high ambient temperature (more than 85°C)

This failure occurs if the temperature inside the rear side radar
moves out of working temperature
range.

When the internal temperature returns
within the working temperature range, the
triggered indication is reset.

B2341

RADAR ASSY B&&S degradation
of detecting performance

This failure occurs if radar irradiation is blocked or radar reflection
cannot be received.

When the radar properly irradiates or
receives the reflected signal, the triggered
indication is reset.

B2350

RADAR ASSY B&&S Communication error between Master and
Slave

This failure occurs if there is any
trouble between the Master and
Slave in the rear side radar.

When the ignition is set to ON and the private CAN operates normally, the triggered
indication is reset.

Adjust the axis of the radar.

Radar Axis Alignment
Alignment of the Radar Axis is performed after removal/installation or replacement of a SRVD
Radar unit. This includes body repairs or the replacement of a mounting bracket.
Note: This procedure outlines the Radar Axis Alignment for the Master (LH) Radar
unit. Alignment of the Slave (RH) Radar unit is accomplished with the same
procedure on the opposite side of the vehicle.
Secure an open and level area with 13.12 ft (4m) from the rear and side of the vehicle.

If the result of the Axis Alignment is out of the permissive range, it is possible that the reflector
position may be incorrect or the Radar unit bracket/mounting location may be deformed.
The maximum allowable misalignment of the Radar unit is ±5°. If this value is greater than ±5°
then bent or damaged components exist.

Brakes

The 2015 Legacy and Outback are equipped with a new rear braking system and parking brake.
Classified as a caliper integrated Electronic Parking Brake (EPB) system, the new rear brakes
provide normal hydraulic braking functions and parking brake features for the following:
-

Parking Brake
Hill Holder*
Stay Stop Control for Eyesight*
Emergency Brake
Sliding Prevention
Temperature Compensation

Note:

Automatic Release Control, for the EPB is identical to the current model year
Legacy and Outback.

Note:

There is no manual release for the EPB.

Rear Caliper

Caliper Spring Clip

The spring clip must be able to slide smoothly across the mounting bracket as the outer pad wears.
If the spring clip movement is restricted, premature inner brake pad wear will occur. The back side
of the rear brake caliper is secured to the mounting bracket with two internal hex drive guide pins.

The guide pins allow the caliper to float on the mounting bracket, providing for automatic clearance

EPB Construction and Operation

8-12
Caliper (Artwork)

The EPB operates from the movement of a brushed DC voltage motor which is controlled by the
Hydraulic Control Unit. A series of worm gears and reduction gears provide bidirectional movement
of a ball nut that is keyed to the hydraulic piston. If the EPB is activated, the ball nut is screwed
downward into the back face of the hydraulic piston and the piston moves into the inner brake pad.
