All diagnosis begins in SYMPTOM CHARTS with QT Powertrain Control Module (PCM) Quick Test. If the PCM Quick Test is completed and no diagnostic trouble codes (DTCs) have been retrieved, the technician is directed to the NO DIAGNOSTIC TROUBLE CODES (DTCS) PRESENT SYMPTOM CHART INDEX The No Diagnostic Trouble Codes (DTCs) Present Symptom Chart Index contains the list of symptoms addressed in this service information, and directs the technician to the appropriate chart in the NO DIAGNOSTIC TROUBLE CODES (DTCS) PRESENT SYMPTOM CHARTS . If no PCM DTCs are present and the vehicle symptom is not listed in the No Diagnostic Trouble Codes (DTCs) Present Symptom Chart Index, the technician should go to the appropriate service information to continue diagnosis.
