2007 New Model Update

2007 LEGACY

The 2007 Legacy and Outback models are described from pages 53 to 78. Please review the
material on these pages to become familiar with the systems equipped on each model. In cases
where the systems are shared with the Subaru B-9 Tribeca, refer to the Subaru B-9 Tribeca chapter
in the beginning of this reference booklet.

VDC System

The VDC system of the 2007 Legacy is very similar to past model years with the exception of the
Hydraulic Control Unit (HCU). This year the HCU is designed to operate more than one type of
vehicle. Upon installation, a new HCU must be initialized (*Selection of Parameter) to the vehicle
in which it is installed. This process is accomplished with the SMIII using the procedure outline
below. This information can also be found in the help section of the SMIII.
The SMIII is also used to confirm that a HCU has been previously initialized correctly to a vehicle
(Confirm on Parameter). This would be performed during diagnosis when the operation of the HCU
is in question.
*Selection of parameter is the process of selecting the operating parameters of the vehicle to the
HCU.

Selection of Parameter

This function is used to select/register parameters when the VDC control module has been replaced
with a normal spare part.
NOTE:
• Always execute "Clear Memory" after operating this function.
• This function cannot be used with a control module that is not a normal spare part.
• To confirm the applied model, refer to the "Model No. Plate" affixed to the vehicle. The
location of the model No. plate is shown in the *Service Manual.

Registration Procedure

1. Prepare the SDI, diagnosis cable, USB cable, and a PC with the PC application
installed.
2. Use the diagnosis cable to connect the SDI to the data link connector of the
vehicle.
NOTE: SDI POWER WILL TURN ON AUTOMATICALLY WHEN THE DIAGNOSIS CABLE IS
CONNECTED TO THE VEHICLE. IF THE PWR LED OF THE SDI DOES NOT LIGHT,
TURN ON THE VEHICLE'S IGNITION SWITCH OR START THE ENGINE, AND THEN
PRESS THE SDI [PWR] KEY AND CHECK AGAIN TO SEE IF THE PWR LED OF THE SDI
LIGHTS.
* Refer to STIS (Subaru Technical Infromation System)
