Problem Symptoms Table
If a normal system code is displayed during the DTC check but the problem still occurs, check the circuits for each problem symptom in the order given in the table below and proceed to the relevant troubleshooting page.
HINT:
Inspect the "Fuse" and "Relay" before confirming the suspected areas as shown in the table below.
Inspect each malfunction circuit in numerical order for the corresponding symptom.
If the malfunction still exists even after checking and confirming that all the circuits are normal, replace the ECM.
