ABSTRACT:
A self diagnosing circuit for a load control circuit is disclosed, which detects the state of a driving line connected with a load and protects a load driving circuit by turning off transistors in the load driving circuit, when a grounding accident occurs, in which, in the case where an error is produced so that the load doesn't work normally, responding to a control signal, a process is executed, corresponding to the content of that error and the content of that error is stored or made known to the exterior through display means.
