Symptom Charts

All diagnosis begins with the 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 DTCS PRESENT SYMPTOM CHART INDEX . The No DTCs Present Symptom Chart Index contains the list of symptoms addressed, and will send the technician to the appropriate No DTCs Present Symptom Chart Index. If no PCM DTCs are present and the vehicle symptom is not listed in the No DTCs Present Symptom Chart Index, the technician should refer to the appropriate service information article to continue diagnosis.
