DTC C1225: SM Solenoid Circuit; DTC C1468: SFR Solenoid Circuit; DTC C1469: SFL Solenoid Circuit; DTC C146A: SRR Solenoid Circuit; DTC C146B: SRL Solenoid Circuit [11/2016 - ]: Procedure

RECONFIRM DTC

HINT:

These codes are detected when a problem is determined in the skid control ECU (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 DTCs are output before replacing the skid control ECU (brake actuator assembly).

Clear the DTCs.
Refer to DTC CHECK / CLEAR [11/2016 - ]

Chassis > ABS/VSC/TRAC > Clear DTCs
Turn the ignition switch off.
Start the engine.
Perform a road test.
Check if the same DTC is output.
Refer to DTC CHECK / CLEAR [11/2016 - ]

Chassis > ABS/VSC/TRAC > Trouble Codes

HINT:
- The skid control ECU (brake actuator assembly) performs self diagnosis of the solenoid circuit after the ignition switch is turned to ON.
- If the normal system code is output (no DTCs are output), slightly jiggle the connectors, wire harness, and fuses of the skid control ECU (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.
