Symptom Charts

All diagnosis begins in QT: POWERTRAIN CONTROL MODULE (PCM) QUICK TEST . If the PCM Quick Test is completed and no diagnostic trouble codes (DTCs) are retrieved, the technician may be directed to the NO DIAGNOSTIC TROUBLE CODES (DTCS) PRESENT SYMPTOM CHART INDEX (refer to SYMPTOM CHARTS for details). The No Diagnostic Trouble Codes (DTCs) Present Symptom Chart Index contains the list of symptoms addressed in this service information, and sends the technician to the appropriate 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 CHARTS , the technician should refer to the appropriate Service Information article to continue diagnosis.
