Symptom Troubleshooting [Engine Mechanical]: Foreword
- When the customer reports a vehicle malfunction, check the Malfunction Indicator Lamp (MIL) indication and Diagnostic Trouble Code (DTC), then diagnose the malfunction according to the following flowchart:
- If a DTC exists, diagnose the applicable DTC inspection. (See DTC TABLE
.)
- If no DTC exists and the MIL does not illuminate or flash, diagnose the applicable symptom troubleshooting. (See QUICK DIAGNOSTIC CHART .)
