DTC C2228-08: ACC Actuator Failure - TCU: General Description

The ABS/ESP sends request data, such as torque reduction, the number of fuel cut cylinders, and the ESP (ESC) control request, to the PCM (ECM & TCM) through CAN bus line. The PCM (ECM) conducts the fuel cut according to the request from the ABS/ESP and then retards ignition timing. The PCM (TCM) maintains current gear position during the ESP (ESC) control in order to prevent a Kick down shift.
