Repair or replace faulty parts or perform adjustments as necessary.
When replacing the skid control ECU, sensor, etc., turn the ignition switch off.
Use the table below to help
determine the cause of a problem. The likely causes of the problem are indicated
in descending order. Check each suspected area in order.

switch off.
| Symptom | Suspected Area | See page |
| ABS and/or EBD does not operate | Check the DTC again and make sure that the normal system code is output. | (*1) |
| IG power source circuit | C1241 | |
| Front speed sensor circuit | C0200, C0205 | |
| Rear speed sensor circuit | C0210, C0215 | |
| Check the brake actuator assembly. If abnormal, check the hydraulic circuit for leakage. | BRAKE ACTUATOR | |
| If the symptoms still occur even after the above circuits in suspected areas have been inspected and proved to be normal, replace the skid control ECU. | (*1) | |
