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 troubleshooting service information.

NOTE:

When replacing the brake actuator assembly, sensor, etc., turn the ignition switch off.

HINT: 

Inspect the fuse and relay before investigating the suspected areas as shown in the table below. Inspect each malfunction circuit in numerical order for the corresponding symptom.

ANTI-LOCK BRAKE SYSTEM:
