C05061F Right Front Wheel Speed Sensor Circuit Intermittent
·

The speed sensor signal is excessively noisy.

·

The calculated change in wheel speed is more than 980 m/s2 for 5*1 or 20*2 seconds or more.

·

The calculated change in wheel speed fluctuates between more than 500 m/s2 and less than -500 m/s2 for 5*1 or 20*2 seconds or more.

·

When the vehicle speed is low, excessive noise in the speed sensor pulse signal is detected 3 times or more within 0.005 seconds for 5*1 or 20*2 seconds or more.


·

Front speed sensor RH

·

Front speed sensor rotor RH (front axle hub sub-assembly RH)


Comes on Brake/EPB
·

SAE Code: C050A (Case 1 and 2)

·

Output ECU: Skid control ECU (brake actuator assembly)



*1: The stop light switch assembly is OFF.

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 FRONT SPEED SENSOR RH (CHECK FOR FOREIGN MATTER)
a.

Remove the front speed sensor RH.

Click hereBrake>BRAKE CONTROL / DYNAMIC CONTROL SYSTEMS>FRONT SPEED SENSOR>REMOVAL


b.

Check the front speed sensor RH.

OK:

The front speed sensor RH tip is free of oil and foreign matter.


HINT:

If foreign matter of 1 mm (0.03937 in.) x 1 mm (0.03937 in.) or more is adhered to the front speed sensor RH, this DTC may be stored.

2.CHECK FRONT SPEED SENSOR ROTOR RH (CHECK FOR FOREIGN MATTER)
a.

Remove the component with the front speed sensor rotor RH.

Click hereDrivetrain>AXLE AND DIFFERENTIAL>FRONT AXLE HUB>REMOVAL


b.

Check the front speed sensor rotor RH.

OK:

The front speed sensor rotor RH is free of oil and foreign matter.


HINT:
·

If foreign matter of 1 mm (0.03937 in.) x 1 mm (0.03937 in.) or more is adhered to the front speed sensor rotor RH, this DTC may be stored.

·

The front speed sensor rotor RH is incorporated into the front axle hub sub-assembly RH.

If the front speed sensor rotor RH needs to be replaced, replace it together with the front axle hub sub-assembly RH.
