DTC C121C: Torque request signal rejection
| CAUTION | If there is any problem in the CAN bus lines, an incorrect diagnostic trouble code may be set. Prior to this diagnosis, diagnose the CAN bus lines. Whenever the ECU is replaced, ensure that the CAN bus lines are normal. When the hydraulic unit (integrated with ASC-ECU) is replaced, always perform the calibration of steering wheel sensor, G and yaw rate sensor, brake fluid pressure sensor, cut valve, and inlet valve.(Refer to IN THE EVENT OF A DISCHARGED BATTERY, STEERING WHEEL SENSOR CALIBRATION, MASTER CYLINDER BRAKE FLUID PRESSURE SENSOR CALIBRATION, and CALIBRATION OF CUT VALVE AND INLET VALVE.) |
