System Diagram

When Ignition Switch is turned ON, ECM performs the following functions:

• To ensure full flow, the fuel pump is actuated via the FPCM (only at first time ignition ON after unlocking the vehicle).
• MIL (Malfunction Indicator Lamp) is actuated for the lamp check by the ECM via CAN communication.
• Malfunction memory in the ECM can be read out and deleted via the diagnosis tool.
• The Throttle Valve Actuator checks its return spring (by the position of the throttle valve) and adapts the position of the actuator, if necessary.
