摘要：A system for diagnosing an internal combustion engine having a starter and astarter operation switch. The system comprises a starter operation diagnosing circuitresponsive to output voltage of the starter operation switch for producing an outputwhen the output voltage deflects from a predetermined value, an engine speeddetecting circuit for detecting an engine speed at cranking of the engine, a first gateresponsive to the output voltage of the detecting circuit for producing an output for apredetermined time. A second gate is responsive to the output of the first gate to passthe output of the starter operation diagnosing circuit, and a warning lamp is operated bya signal passing through the second gate.
