DTC C1290: CAN time-out error: Notes
WARNING: This page is about a different variant/trim than selected.
CAUTION:
- If diagnostic trouble code No. C1290 is set in ASC-ECU, always diagnose the CAN bus lines. If there is any fault in the CAN bus lines, an incorrect DTC may be set.
- When the diagnostic trouble code No. C1290 is set in ASC-ECU, a 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.
- Whenever the ECU is replaced, ensure that the communication circuit is normal.
- When the steering wheel sensor is replaced, always perform calibration to make ASC-ECU learn the neutral point. (Refer to STEERING WHEEL SENSOR CALIBRATION .)
- 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 G AND YAW RATE SENSOR CALIBRATION , STEERING WHEEL SENSOR CALIBRATION , MASTER CYLINDER BRAKE FLUID PRESSURE SENSOR CALIBRATION , and CALIBRATION OF CUT VALVE AND INLET VALVE .)
