NOTE: If B1504 is detected when vehicle is not exposed to light (indoor, etc.), check again for DTC with light from incandescent light applied to sunload sensor, referring to Sunload Sensor Inspection. If B1504 is not detected in this check, sunload sensor is in good condition.

If communication is possible in this case, scan tool is good condition. Then check data link connector and serial data line (circuit) in the vehicle with which communication was not possible.
