Anti-Lock Brake System -- Problem Symptoms Table |
If there are no DTCs output and 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 actuator assembly, sensors, etc., turn the ignition switch off.
- 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.
| Symptom | Suspected Area | See page |
| ABS and/or EBD does not operate | Check for DTCs again and make sure that the normal system code is output. | COROLLA_ZRE142 RM000000XHV0F3X.html |

| Rear speed sensor circuit | COROLLA_ZRE142 RM000000XIA0I3X.html | |
| Check the brake actuator assembly using the Techstream. (Check brake actuator assembly operation using the Active Test function.) If abnormal, check the hydraulic circuit for leaks. | COROLLA_ZRE142 RM000002VQP00OX.html | |
| If the symptoms still occur even after the above circuits in suspected areas have been inspected and proved to be normal, replace the brake actuator assembly (skid control ECU). | COROLLA_ZRE142 RM0000013P6022X.html | |
