ANTI-LOCK BRAKE SYSTEM PROBLEM SYMPTOMS TABLE
If there are no DTCs output 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 "See page".
Note
When replacing the master cylinder solenoid, sensor, etc., turn the ignition switch off.
Tech Tips
-
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.
