Idle Control Valves on the throttle body were fitted to MY 2000 and 2001 Legacy and Outback models with manual transaxle. Before removing it, you need to disconnect the cable from the negative battery terminal, detach the electrical connector from the Idle Control Valve, remove the air bypass hose from the Idle Control Valve, and take off the mounting screws of the Idle Control Valve along side the valve itself. The installation is done by reversing the order of removal. On all other MY 2000 through MY 2004 models (except MY 2004 turbocharged models), also Idle Control Valves are located on throttle bodies. Disconnecting the cable from the negative battery terminal, detaching the electrical connector of the Idle Control Valve, taking off the mounting screws of the Idle Control Valve as well as the Idle Control Valve itself facilitate its removal. Then install this device in reverse procedure used for its removal. In case of MY 2004 turbocharged models and all MY 2005-onward releases have been provided with an electronic control throttle system while their electronic throttle bodies lack an idle control (IAC) motor which instead is internal to the PCM that manipulates throttle plate angle as required by inputs coming from a number of sensors providing informative data.

The first step is to disconnect the cable from the negative battery terminal.
