C055595 |
Left Front Wheel Speed Sensor Incorrect Component Installed |
The front speed sensor LH is installed incorrectly. |
Front speed sensor LH |
Comes on |
SAE Code: C0555 |
MONITOR DESCRIPTION
The skid control ECU (brake actuator assembly) has a speed sensor circuit self-diagnosis function.
When the vehicle is stopped, the speed sensor supply voltage exceeds a certain value, and the self-diagnosis function detects an incorrectly installed speed sensor, the skid control ECU (brake actuator assembly) illuminates the MIL and stores this DTC.

CONFIRMATION DRIVING PATTERN
NOTICE:
When performing the normal judgment procedure, make sure that the driver door is closed and is not opened at any time during the procedure.
HINT:
- After repair has been completed, clear the DTC and then check that the vehicle has returned to normal by performing the following All Readiness check procedure.
- When clearing the permanent DTCs, refer to the "CLEAR PERMANENT DTC" procedure.
- Connect the GTS to the DLC3.
- Turn the ignition switch to ON and turn the GTS on.
- Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).
- Turn the ignition switch off.
- Turn the ignition switch to ON and turn the GTS on.
-
Wait for 3 seconds or more. [*]
HINT:
[*]: Normal judgment procedure.
The normal judgment procedure is used to complete DTC judgment and also used when clearing permanent DTCs.
-
Enter the following menus: Chassis / Brake/EPB* / Utility / All Readiness.

-
Check the DTC judgment result.
HINT:
- If the judgment result shows NORMAL, the system is normal.
- If the judgment result shows ABNORMAL, the system has a malfunction.
- If the judgment result shows INCOMPLETE, perform driving pattern again.
