Rear
REAR ABS WHEEL-SPEED SENSOR INSPECTIONInstallation 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 (0.5471)
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 inch) 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.
