Trouble Area

C05061F

Right Front Wheel Speed Sensor Circuit Intermittent

Any of the following is detected:

  • When the +BS terminal voltage is 17.4 V or less, an open in the sensor signal circuit of a malfunctioning area occurs 255 times or more.
  • When the +BS terminal voltage is 17.4 V or less at a vehicle speed of 20 km/h (12 mph) or more, noise occurs in the sensor signals of a malfunctioning wheel 75 times or more within 5 seconds.
  • When the +BS terminal voltage is 17.4 V or less at a vehicle speed of 10 km/h (6 mph) or more, noise occurs once per rotor rotation for 15 seconds or more.
  • Front speed sensor RH
  • Speed sensor installation
  • Front speed sensor rotor RH (front axle hub sub-assembly RH)

PROCEDURE

1.

READ VALUE USING GTS (FR WHEEL SPEED, MOMENTARY INTERRUPTION)

(a) While monitoring the values of the Data List, perform a road test and attempt to reproduce the problem symptoms based on the interview with the customer and the vehicle conditions stored as Freeze Frame Data when the DTC was stored.

3.

CHECK FRONT SPEED SENSOR RH (CHECK FOR FOREIGN MATTER)

(a) Remove the front speed sensor RH, and confirm that there is no foreign matter, oil or grease on the front speed sensor tip RH.

OK:

The front speed sensor tip 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 RH, this DTC may be stored.

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

(a) Confirm that there is no foreign matter, oil or grease on 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.
  • 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.
