DTC C1290: CAN time-out error: Notes
CAUTION:
- If the diagnostic trouble code C1290 is set in ASC-ECU, always diagnose the CAN bus line. If there is any fault in the CAN bus lines, an incorrect diagnostic trouble code may be set. In this case, the set diagnostic trouble code is not highly reliable.
- Before replacing the ECU, ensure that the communication circuit is normal.
- When the diagnostic trouble code C1290 is set in ASC-ECU, the diagnostic trouble code for another system may also be set. When the diagnostic trouble code for another system is set, carry out diagnosis for that system first.
