Problem Symptom Confirmation
Check if what the customer claimed in "Customer Questionnaire" is accurately found in the vehicle. If that symptom is

DTC indicates malfunction that occurred in the system but does not indicate whether it exists now or it occurred in the

whether or not any fault exists.
Troubleshooting for DTC
Based on the DTC indicated in Step 3 and referring to applicable DTC flow, locate the cause of the trouble, namely in
