Code C1611 KIA Description

The Hydraulic Electronic Control Unit (HECU) sends requirement data, such as Torque reduction, the number of fuel cut cylinders, and ESC control requests, to the Powertrain Control Module (PCM) through Controller Area Network (CAN) bus line. The Powertrain Control Module performs fuel cut functions according to requests from the HECU and retards ignition timing by torque reduction requests. The Transmission Control Module (TCM) maintains current gear positions during ESC control time, in order not to increase power which causes a Kickdown shift.
The HECU checks the CAN communication lines for normal ESC control and sets this code if a Powertrain Control Module message is not received within a predefined time.
