DTC C121A: SAS Initialization: Notes
CAUTION:
- If there is any problem in the CAN bus lines, an incorrect DTC may be set. Prior to this diagnosis, diagnose the CAN bus lines (Refer to CAN BUS DIAGNOSTICS TABLE ).
- Whenever ECU is replaced, ensure that the CAN bus lines are normal.
- When the column switch assembly (integrated with steering wheel sensor) is replaced, always carry out calibration to make ASC-ECU learn the neutral point (Refer to G AND YAW RATE SENSOR CALIBRATION ).
