Code No.B2350
Lighting switch malfunction
Code No.B2351 Wiper/washer switch malfunction
COMMENTS ON TROUBLE SYMPTOM
- If the ETACS-ECU receives the lighting switch fail signal, the ETACS-ECU
sets diagnosis code No. B2350.
- If the ETACS-ECU receives the wiper/washer switch fail signal, the ETACS-ECU
sets diagnosis code No. B2351.
- The steering wheel sensor is incorporated in the column switch assembly. When you
replace the switch, you must always calibrate the sensor to make the ASC-ECU learn the neutral
position of the steering wheel (Refer to GROUP 35C - On-vehicle service - Steering
wheel sensor calibration).
PROBABLE CAUSES
- Malfunction of column switch (with built-in column-ECU)
- Malfunction of the ETACS-ECU
