CAUTION:
Although Diagnostic Quick Test appears to be a fast and powerful diagnostic aid, it unfortunately cannot detect all possible failures that can occur within the system. Therefore, the Diagnostic Quick Test procedure in this article has been carefully constructed to guide you and refer you to Pinpoint Tests that inspect components and circuitry associated with a particular symptom.
