Pcm (ECM/TCM): Ems No Request
WARNING: This page is about a different car, the 2021 Hyundai Kona. However, it is still accessible from the selected car via links, so may be relevant.
While the ignition switch is ON, the PCM/ECM receives information from the ICM and permits fuel injection by confirming that the CODE memorized in the PCM/ECM coincides with the one in the ICM.
Once the ID code from a transponder is verified by the ICM and registered, an answer signal will be sent to the PCM/ECM. The ICM then sends a START or NO START signal to the PCM/ECM.
