MAIN COMPONENTS AND FUNCTIONS
| Parts name | Functional description | ||
|---|---|---|---|
| Wireless control module (WCM) | Controls the keyless entry functions, TPMS functions and starting of the engine by using the following communications.
|
||
| Steering lock (key reminder switch) | Wireless communication with ignition key. Receives the ID code (key ID) of the ignition key needed for starting the engine, converts them into data and sends them to WCM. |
||
| Ignition key | The ignition key receives signals sent from WCM, certifies the key ID, calculates the key ID, and sends the reply data signal to WCM. The ignition key also sends signals to WCM when the lock/unlock button and panic button on it are operated. | ||
| Combination meter (Multi information display, TPMS warning light) | Communicates with WCM via CAN. Send ignition switch status. Receives the warning request or warning information from WCM, activates(1) the TPMS warning light. Warning symbol and message is additionally displayed on the Multi information display. | ||
| ETACS-ECU | Communicates with WCM via CAN. By the door lock/unlock request or panic alarm request from WCM, ETACS-ECU outputs the lock/unlock signal or panic alarm signal. When the door lock/unlock signal is output, ETACS-ECU flashes or illuminates the turn signal light and dome light to notify that the lock/unlock operation is performed. | ||
| ASC-ECU | Communicates with WCM via CAN. Sends the vehicle speed data. | ||
| Engine control module (ECM) | Communication with WCM via CAN. Send atmospheric pressure data. | ||
| TPMS transmitter | Measure tire pressure directly, then send radio frequency signal to WCM. | ||
*: Flashes for about 1 minute and then continuously illuminated for TPMS malfunction warning. |
