Abstract: PURPOSE: An anti-overheat device for a starting motor and a method thereof is provided to improve the durability of the starting motor by preventing damages and overheat caused by a continuous starting demand when a fuel pump, an injector and an ignition coil do not operate. CONSTITUTION: An anti-overheat device for a starting motor comprises a battery(101), an ignition switch(102), an inhibitor switch(103), starting relay(104) and control unit(106). The ignition switch detects a starting request. The inhibitor switch detects a selection about N or P range of a shift lever. The starting relay controls cranking operations of the starting motor(105). If a starting request of the ignition switch continues over a set-up time, the control unit runs anti-overheat control operations to keep the starting relay opened.

Abstract: PURPOSE: An ignition diagnosis method is provided to prevent wrong diagnosis using one variable since a coil current and a coil voltage are respectively compared to a reference current and a reference voltage to determine the reason of failure. CONSTITUTION: An ignition diagnosis method comprises next steps. A MICOM outputs an ignition signal to burn mixed gas in a cylinder to operate an engine(S1). If the ignition signal is output, the current of a coil becomes a reference current(S2) and maintains for below a first disconnection reference time(S3), then the MICOM generates a first failure code due to disconnection(S4). If the ignition signal is not output, the current of a coil maintains at below a reference voltage for over a second disconnection reference time(S5), then the MICOM generates a second failure code due to disconnection(S6). The MICOM determines that failure due to disconnection occurs if the first or second failure code is generated(S8).

Abstract: PURPOSE: An electronic throttle valve control device and a method thereof are provided to prevent engine stall and the revolution per minute of the engine from rapidly increasing by controlling the drive duty of a direct current motor operating a throttle valve. CONSTITUTION: A method for controlling an electronic throttle valve comprises following steps. Required torque is decided and the position of the throttle valve is adjusted. The signals of a first throttle position sensor and a second throttle position sensor and motor control current are detected for feed-back control(S103,S104). The change rate of the signals of the first throttle position sensor and the second throttle position sensor signal is calculated(S105) and whether the change rate exceeds the fixed standard value or not is determined(S106). When the change rate exceeds the standard value, noise is generated on the TPS signals.

Abstract: A CAN(controller area network) line diagnosis method is provided to prohibit CAN line diagnosis when any of CAN communication modules does not respond. A CAN line diagnosis method includes the steps of performing auto detection to search whether a CAN communication module is installed at an automobile by checking a response message from a CAN communication module, and bypassing a CAN line diagnosis process when there is no response from the CAN communication module, determining whether a response message from the CAN communication module exists when it is confirmed that at least one CAN communication module is installed, and bypassing the CAN line diagnosis process.
