Section 3: Symptom Charts

All diagnosis begins in Section 3 with the 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 in Section 3. The No DTCs Present Symptom Chart Index contains the list of symptoms addressed in this article, and directs the technician to the appropriate chart in the No DTCs Present Symptom Chart. If no PCM DTCs are present and the vehicle symptom is not listed in the No DTCs Present Symptom Chart Index, the technician should go to the appropriate component Diagnostic Information to continue diagnosis.
