ABS/ESC - C1616 CAN Bus off - General Information

Component Location





General Description

The HECU send 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 ESC control time, in order not to increase power which causes a Kickdown shift.

DTC Description

The HECU checks the CAN communication lines for normal ESC control, and sets this code if re-initialization is tried for 15 times in sequence without success.
