However, troubleshooting should be performed referring to the inspection methods described in this manual.\n\nBefore beginning inspection, it is best to first make a simple check of the fuses, fusible links and condition of the connectors.\n\nThe following troubleshooting procedures are based on the supposition that the trouble lies in the short or open circuit in a component outside the computer or a poor connection in the connector.\n\nIf engine check occurs even though proper operation is connected to the computer connector, then it can be assumed the computer is faulty and should be
