BRAKE CONTROL / DYNAMIC CONTROL SYSTEMS: ELECTRONICALLY CONTROLLED BRAKE SYSTEM: PROBLEM SYMPTOMS TABLE

If there are no DTCs 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 page.

NOTICE:
When replacing the brake booster with master cylinder (skid control ECU), sensor, etc., make sure that the power switch is turned off, the stop light switch is off, and 2 minutes have elapsed since the driver's door was closed.

HINT
* Since the hydraulic passage is blocked off by the master cut solenoid during electronically controlled brake system control, there is no kickback (vibration) to the brake pedal, creating a quiet sound even while the ABS is operating.
* 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.
