id041300801200
Installation Visual Inspection
1. Inspect for the following:
-
• If there is any malfunction, replace the part.
-
(1) Excessive looseness or play of the ABS wheel-speed sensor
-
(2) Deformation of the ABS wheel-speed sensor
-
(3) Deformation or damage of the ABS sensor rotor
Clearance Inspection
1. Remove the rear ABS wheel-speed sensor.
2. Measure the distance between the rear ABS wheel-speed sensor installation surface and the ABS sensor rotor. This is dimension A.
3. Calculate the clearance between the rear ABS wheel-speed sensor and the ABS sensor rotor using the following formula:
-
Clearance (mm {in}) = A -13.9 {0.547}
4. Verify that the clearance between the ABS sensor rotor and the rear ABS wheel-speed sensor is as indicated below.
-
• If there is any malfunction, replace it.
-
Clearance
-
1.46 mm {0.057 in} or less
Sensor Output Value Inspection
-
Caution
-
• Resistance inspection using other testers may cause damage to the ABS wheel-speed sensor internal circuit. Be sure to use the WDS or equivalent to inspect the ABS wheel-speed sensor.
1. Turn the ignition switch off.
2. Connect the WDS or equivalent to the DLC-2.
3. Select the following PIDs using the WDS or equivalent:
-
• LR_WSPD
-
(LR wheel-speed sensor)
-
• RR_WSPD
-
(RR wheel-speed sensor)
4. Start the engine and drive the vehicle.
5. Verify that the display of the WDS or equivalent shows the same value as the speedometer.
-
• If there is any malfunction, replace the ABS wheel-speed sensor.
