NOTE:
The starter relay control is performed in immobilizer system. When the immobilizer control module detects a nonconformity of reference code, it immediately outputs a starter relay cut signal to ECM, and then ECM stops the starter relay operation. In this case, engine does not start, and DTC is not recorded in ECM. Therefore, check DTC for the immobilizer control module to identify the cause of the engine not starting.
