DTC C1225: SA1 Solenoid Circuit; DTC C1226: SA2 Solenoid Circuit; DTC C1227: SA3 Solenoid Circuit; DTC C1228: STR Solenoid Circuit; DTC C1468: SFR Solenoid Circuit; DTC C1469: SFL Solenoid Circuit; DTC C146A: SRR Solenoid Circuit; DTC C146B: SRL Solenoid Circuit: Procedure

HINT: 

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.

1. Clear the DTCs. Refer to DTC CHECK / CLEAR [03/2012 - ] .
2. Turn the ignition switch off.
3. Start the engine.
4. Drive the vehicle at a speed of 20 km/h (12 mph) or more.
5. Check if the same DTC is output. Refer to DTC CHECK / CLEAR [03/2012 - ] .

   DTCs C1225, C1226, C1227, C1228, C1468, C1469, C146A and/or C146B are output.	B

   HINT: 

   • 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.
