In the Ignition ON position, the ECM/PCM receives information from the ICM and permits injection to take place If the CODE memorized in ECM/PCM is coincided with ICM.

When the ID code from the transponder is verified by the ICM then the registering sequence is complete and a answer signal is sent to the ECM/PCM.

The ICM sends a START or NO START signal to the ECM/PCM.
