1. Inspect the following items:
If there is any malfunction, replace the applicable part.
a. Excessive play or deformation of the ABS wheel-speed sensor
1. Remove the ABS wheel-speed sensor.
2. Measure the distance between the 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-14 {0.55}
4. Verify that the clearance between the ABS sensor rotor and the ABS wheel-speed sensor is as indicated below.
If there is any malfunction, replace it.
Clearance
0.3—1.1 mm {0.02—0.04 in}
1. Switch the ignition off.
2. Connect the M-MDS to the DLC-2.
3. Select the following PIDs using the M-MDS:
WSPD_SEN_LR (LR ABS wheel-speed sensor)
WSPD_SEN_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 ABS wheel-speed sensor.
