DIAGNOSTIC TROUBLE CODE CHART

B1400/00-B1435/35:

B1442/42-B1461/61:

If a malfunction code is displayed during the DTC check (sensor check), check the circuit listed for that code in the table.

HINT:
-* 1 If the room temperature is approximately -20 degrees C (-4 degrees F) or lower, DTC B1411/11 may be output even though the system is normal.
- *2 If the ambient temperature is approximately -50 degrees C (-58 degrees F) or lower, a DTC may be output even though the system is normal.
- *3 If the check is being performed in a dark place, DTC B1421/21 (solar sensor circuit abnormal) could be displayed. In this case, perform DTC check again while shining a light, such as inspection light, on the solar sensor. If DTC B1421/21 is still displayed, there could be trouble in the solar sensor circuit.
- *4 If the check is being performed in a dark place, DTC B1424/24 (solar sensor circuit abnormal) could be displayed. In this case, perform DTC check again while shining a light, such as inspection light, on the solar sensor. If DTC B1424/24 is still displayed, there could be trouble in the solar sensor circuit.
- *5 If the check is being performed in a dark place, DTC B1421/21 (solar sensor circuit abnormal) could be displayed. In this case, perform DTC check again while shining a light, such as inspection light, on the solar sensor. If DTC B1421/21 is still displayed, there could be trouble in the solar sensor circuit.
