Section 3: Symptom Charts

This information is where all diagnosis begins in the Powertrain Control Module (PCM)/Transaxle Control Module (TCM) Quick Test. If the Powertrain Control Module (PCM)/Transaxle Control Module (TCM) Quick Test is completed and no DTCs are retrieved, the technician may be directed to the No Diagnostic Trouble Codes (DTCs) Present Symptom Chart Index  . The No Diagnostic Trouble Code (DTC) Present Symptom Chart Index contains the list of symptoms addressed in this service information, and sends the technician to the appropriate chart in the No Diagnostic Trouble Codes (DTCs) Present Symptom Charts  . If no PCM or TCM DTCs are present and the vehicle symptom is not listed in the No Diagnostic Trouble Code (DTC) Present Symptom Chart Index, the technician should go to the appropriate information to continue diagnosis.
