37 -ELECTRIC POWER STEERING (EPS) > TROUBLESHOOTING > DIAGNOSIS CODE PROCEDURES > Diagnosis code No.C1567 Invalid Data Received for Vehicle Speed(CRC)
Code No.C1567 Invalid data received for vehicle speed (CRC)
Code No.C1568 Invalid data received for vehicle speed (message counter)
| caution | - If there is any problem in the CAN bus lines, an incorrect diagnosis code may be set. Prior to this diagnosis, diagnose the CAN bus lines (Refer to GROUP 54C, CAN Bus Diagnostics Table
). - Whenever ECU is replaced, ensure that the CAN bus lines are normal.

OPERATION
The EPS-ECU in the vehicle speed information (including error detection signal) from the ASC-ECU.
FUNCTION
The EPS-ECU controls the driving force of the motor based on the vehicle speed information from the ASC-ECU.
TROUBLE JUDGEMENT
Check Conditions
- The power supply circuit system diagnosis code (No. C1540, C1541) is not set.
Judgement Criterion
- The EPS-ECU judged the error detection signal of the vehicle speed information to be abnormal.
Fail Safe, Back Up Function
- The EPS-ECU sets diagnosis code No. C1567 and C1568.
- Since the assist force is calculated according to the vehicle speed, the assist is continued, but the assist force may be different from the usual time.
PROBABLE CAUSES
- Malfunction of the ASC-ECU
- Malfunction of the EPS-ECU
