DTC C1626 IMPLAUSIBLE CONTROLCOMPONENT LOCATION
Refer to DTC C1235. C1235
GENERAL DESCRIPTION
The HECU sends requirement data, such as Torque reduction, the number of fuel cut cylinders, and TCS control requests, to the Engine ECU & TCU through CAN bus line. The Engine ECU performs fuel cut functions according to requests from the HECU and retards ignition timing by torque reduction requests. The TCU maintains current gear positions during TCS control time, in order not to increase power which causes a Kickdown shift.
DTC DESCRIPTION
