Chassis > Brake/EPB > Data List
Tester Display Measurement Item Range Normal Condition Diagnostic Note FR Wheel Speed Front wheel speed sensor RH reading Min.: 0.0 km/h (0 mph)
Max.: 6553.5 km/h (4072 mph)Vehicle stopped: 0.0 km/h (0.0 mph) When driving at constant speed: No large fluctuations FR Speed Open Front speed sensor RH open detection Normal / Under intermittent Normal: Momentary interruption not detected
Under intermittent: Momentary interruption detected- Chassis > Brake/EPB > Data List
Tester Display FR Wheel Speed FR Speed Open OK
The values change in accordance with the operation of the vehicle and there is no intermittent operation.
NOTE:Perform the above inspection before removing the sensor and connector.
Result
Proceed to OK NG
Result:
OK
USE SIMULATION METHOD TO CHECK. Refer to HOW TO PROCEED WITH TROUBLESHOOTING [12/2019 - ]
Result:
NG
See step 2
- 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.
- CHECK FRONT SPEED SENSOR RH INSTALLATION
- Turn the ignition switch off.
*1 Front Speed Sensor RH *a Correct *b Incorrect *c 8.5 N.m (87 kgf/cm, 75 in.lbf) *d No clearance - Check the front speed sensor RH installation.
OK
There is no clearance between the front speed sensor RH and front steering knuckle RH.
The installation bolt is tightened properly.
Torque
8.5 N.m (87 kgf/cm, 75 in.lbf)
Result
Proceed to OK NG
Result:
NG
INSTALL FRONT SPEED SENSOR RH CORRECTLY. Refer to INSTALLATION [12/2019 - ]
Result:
OK
See step 3
- Turn the ignition switch off.
- CHECK FRONT SPEED SENSOR RH (CHECK FOR FOREIGN MATTER)
- 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.
Result
Proceed to OK NG
Result:
NG
See step 7
Result:
OK
See step 4
- Remove the front speed sensor RH, and confirm that there is no foreign matter, oil or grease on the front speed sensor tip RH.
- CHECK FRONT SPEED SENSOR ROTOR RH (CHECK FOR FOREIGN MATTER)
- 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.
Result
Proceed to OK NG
Result:
OK
REPLACE FRONT SPEED SENSOR RH AND FRONT SPEED SENSOR ROTOR RH
for Front Speed Sensor RH: Refer to REMOVAL [12/2019 - 10/2022] , or refer to REMOVAL [10/2022 - ]
for Front Speed Sensor Rotor RH: Refer to REMOVAL [12/2019 - 10/2022] , or refer to REMOVAL [10/2022 - 11/2023] , or refer to REMOVAL [11/2023 - ]
Result:
NG
See step 5
- Confirm that there is no foreign matter, oil or grease on the front speed sensor rotor RH.
- CLEAN FRONT SPEED SENSOR ROTOR RH
- Clean the front speed sensor rotor RH.NOTE:
Do not use parts cleaner when cleaning the front speed sensor rotor RH.
