Left Front Wheel Speed Sensor Incorrect Component Installed

The front speed sensor LH is installed incorrectly.

Front speed sensor LH

Comes on

Brake/EPB
  • SAE Code: C0555
  • Output ECU: skid control ECU (brake actuator assembly)

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.
  1. Connect the GTS to the DLC3.
  2. Turn the ignition switch to ON and turn the GTS on.
  3. Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).
  4. Turn the ignition switch off.
  5. Turn the ignition switch to ON (READY) and turn the GTS on.
  6. 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.

  7. Enter the following menus: Chassis / Brake/EPB* / Utility / All Readiness.

    *: Electric Parking Brake System

  8. 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.

PROCEDURE

1.

CHECK PART NUMBER (FRONT SPEED SENSOR LH)

(a) Check that the front speed sensor LH is installed.

OK:

Proper front speed sensor LH is installed.

NOTICE:

If it is necessary to remove components in order to check the front speed sensor LH, follow the relevant installation and removal procedures and precautions for those components.

NG

REPLACE FRONT SPEED SENSOR LH

OK

2.

CLEAR DTC

(a) Clear the DTCs.

Chassis > Brake/EPB > Clear DTCs

(b) Turn the ignition switch off.
