Main components and functions
COMPONENTS FUNCTIONS CHART
| 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.
|
| 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/trunk lid 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* 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, trunk lid open request, or panic alarm request from WCM, ETACS-ECU outputs the lock/unlock signal, trunk lid open 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. |
| ABS-ECU or 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. |
