DTC C1613-08: CAN Signal Error EMS: General Description
WARNING: This page is about a different car, the 2021 Kia Soul. However, it is still accessible from the selected car via links, so may be relevant.
The ESC sends requirement data, such as torque reduction, the number of fuel cut cylinders, and the ESP (ESC) control request, to the ECM/PCM through CAN bus line. The ECM/PCM performs the fuel cut function according to a request signal from the ESC and then retards an ignition timing. The ECM/PCM maintains current gear position during the ESP (ESC) control period in order not to increase power which causes a Kickdown shift.
