Sensor Output Value Inspection

Caution

• Resistance inspection using other testers may cause damage to the front ABS wheel-speed sensor internal circuit. Be sure to use the M-MDS to inspect the front ABS wheel-speed sensor.

1.Switch the ignition off.

2.Connect the M-MDS to the DLC-2.

3.Select the following PIDs using the M-MDS: (See PID/DATA MONITOR INSPECTION.)

• WSPD_SEN_L/F (LF wheel-speed sensor)

• WSPD_SEN_R/F (RF 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 front ABS wheel-speed sensor. (See FRONT ABS WHEEL-SPEED SENSOR REMOVAL/INSTALLATION.)

Installation Visual Inspection

1.Inspect for the following:

• Excessive play of the front ABS wheel-speed sensor

• Deformation of the front ABS wheel-speed sensor

• Deformation or damage of the ABS sensor rotor

― If there is any malfunction, replace the front ABS wheel-speed sensor. (See FRONT ABS WHEEL-SPEED SENSOR REMOVAL/INSTALLATION.)

Clearance Inspection

Preparation prior to inspection

1.Remove the front ABS wheel-speed sensor. (See FRONT ABS WHEEL-SPEED SENSOR REMOVAL/INSTALLATION.)

2.Remove the wheel hub and steering knuckle as a single unit. (See WHEEL HUB, STEERING KNUCKLE REMOVAL/INSTALLATION.)

3.Install the front ABS wheel-speed sensor to the removed wheel hub, steering knuckle component, and tighten to the specified torque.

Clearance inspection

1.Measure the gap between the ABS sensor rotor and front ABS wheel-speed sensor using a feeler gauge.

• If not within the specification, verify the following items and repair or replace if necessary.

― Is there deformation or damage to the ABS sensor rotor?

― Is there deformation or damage to the ABS wheel speed sensor?

― Is there foreign matter adhering?

Servicing after inspection

1.Remove the front ABS wheel-speed sensor from the wheel hub, steering knuckle component.

2.Install the wheel hub, steering knuckle component. (See WHEEL HUB, STEERING KNUCKLE REMOVAL/INSTALLATION.)

3.Install the front ABS wheel-speed sensor. (See FRONT ABS WHEEL-SPEED SENSOR REMOVAL/INSTALLATION.)

4.Inspect the front wheel alignment. (See FRONT WHEEL ALIGNMENT [(US)].)
