These solenoids turn on when signals are received from the skid control ECU and they control the pressure acting on the wheel cylinders to control the braking force.

These codes are detected when a problem is determined in the brake actuator assembly.
The solenoid circuits are in the brake actuator assembly.
Therefore, solenoid circuit inspection and solenoid unit inspection cannot be performed. Be sure to check if any DTC is output before replacing the brake actuator assembly.
Clear the DTCs Click here.
Turn the ignition switch off.
Start the engine.
Drive the vehicle at a speed of 20 km/h (12 mph) or more.
Check if the same DTC is output Click here.
The skid control ECU performs self diagnosis of the solenoid circuit after the ignition switch turned to ON.
If the normal system code is output (No DTCs are output), slightly jiggle the connectors, wire harness, and fuses of the brake actuator assembly.
If any DTCs are output while jiggling a connector or wire harness of the skid control ECU (brake actuator assembly), inspect and repair the connector or wire harness.
If no DTCs were output when reconfirming DTCs, checking for intermittent problems is necessary because it is suspected that the original DTCs were stored due to the poor connection of a connector terminal.
