Problem Symptoms Table

HINT:

Use the table below to help determine the cause of the problem symptom. The potential causes of the symptoms are listed in order of probability in the "Suspected area" column of the table. Check each symptom by checking the suspected areas in the order they are listed. Replace parts as necessary.
The Matrix Chart is divided into 2 chapters.
If the instruction "Proceed to next circuit inspection shown in problem symptoms table" is given in the flowchart of the circuit, proceed to the next suspected area in the table.
If the problem still occurs even though there are no malfunctions in any of the circuits, check the ECM and replace it if necessary.
