Section 3: Symptom Charts

This section is where all diagnosis begins in Step 1: 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 Step 2: No Diagnostic Trouble Code (DTC) Present Symptom Chart Index (refer to SYMPTOM CHARTS article for details). The No Diagnostic Trouble Code (DTC) Present Symptom Chart Index contains the list of symptoms addressed in these articles, and sends the technician to the appropriate Step 3: No Diagnostic Trouble Code (DTC) Present Symptom Chart. If no PCM or TCM DTCs are present and the vehicle symptom is not listed in Step 2: No Diagnostic Trouble Code (DTC) Present Symptom Chart Index, the technician should go to the appropriate article to continue diagnosis.
