REAR ABS WHEEL-SPEED SENSOR INSPECTION[2WD]

Installation Visual Inspection

1. Inspect the following items:
• If there is any malfunction, replace the applicable part.
(1) Excessive play of the ABS wheel-speed sensor
(2) Deformation of the ABS wheel-speed sensor

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 front ABS
wheel-speed sensor and the ABS sensor rotor
using the following formula:
Clearance (mm {in}) = A-15.0
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
• 0.3— 1.1 mm {0.012— 0.043 in}

Sensor Output Value Inspection

1. Turn the ignition switch off.
2. Connect the M-MDS to the DLC-2.
3. Select the following PIDs using the M-MDS:
• WSPD_LR
(LR ABS wheel-speed sensor)
• WSPD_RR
(RR ABS wheel-speed sensor)
4. Start the engine and drive the vehicle.
5. Verify that the display of the M-MDS shows the
same value as the speedometer.
• If there is any malfunction, replace the rear
ABS wheel-speed sensor.
