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.
