Problem Symptoms Table

HINT:

Use PROBLEM SYMPTOMS TABLE 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.

Inspect the fuses and relays related to this system before inspecting the suspected areas below.
