DTC No.	Detection Item	DTC Detection Condition	Trouble Area
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)

• *1: The stop light switch assembly is OFF.
• *2: The stop light switch assembly is ON.

  Procedure to clear warning lights (When not clearing DTCs)

  Procedure
  Repair or replacement. Turn the ignition switch to ON. Drive the vehicle at 54 km/h (34 mph) or more for 3 seconds or more to clear the warning lights.

PROCEDURE

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

(a) Remove the front speed sensor RH.

Click here

(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 1mm x 1mm or more is adhered to the front speed sensor RH, this DTC may be stored.

NG

OK

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

(a) Remove the component with the front speed sensor rotor RH.

Click here

(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 1mm x 1mm or more is adhered to the front speed sensor rotor RH, this DTC may be stored.
