• 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 [L5].)
― If no DTC exists and the MIL does not illuminate or flash, diagnose the applicable symptom troubleshooting. (See
QUICK DIAGNOSTIC CHART [L5].)
