VEHICLE STABILITY CONTROL SYSTEM - PROBLEM SYMPTOMS TABLE
- HINT:
Use the table below to help determine the cause of problem symptoms. If multiple suspected areas are listed, 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.
- NOTICE:
- When replacing the master cylinder or sensor, turn the ignition switch off.
