ABS HU/CM terminal:
RR : A ( + ) — B ( - )
LR : C ( + ) — F ( - )
RF : D ( + ) — G ( - )
LF : E ( + ) — I ( - )

•

Oscilloscope setting:
1 V/DIV (Y), 2 ms/DIV (X), AC range

•

Vehicle condition: Driving 30 km/h (18.6 mph)

FRONT/REAR ABS WHEEL-SPEED SENSOR INSPECTION

A3U041343720W02

Visual Inspection

1. Remove the wheel and tire, and inspect the sensor for looseness and damage. Replace the sensor if

necessary.

Clearance Inspection

1. Inspect the clearance between the wheel-speed

sensor and the sensor rotor.

Clearance

0.3—1.1 mm {0.012—0.043 in}

Resistance Inspection

1. Disconnect the ABS wheel-speed sensor connector.
2. Inspect the resistance at the ABS wheel-speed sensor.

•

If not as specified, replace the ABS wheel-speed sensor.

Resistance

1.3—1.7 kilohm

Voltage Inspection

1. On level ground, jack up the vehicle and support it evenly on safety stands.
2. Disconnect the ABS wheel-speed sensor connector.
3. Inspect each sensor by rotating each wheel one revolution per second.

•

If not as specified, replace the ABS wheel-speed sensor.

Voltage

0.25—1.2 V (AC)

Voltage Pattern Inspection

1. On level ground, jack up the vehicle and support it evenly on safety stands.
2. Disconnect the ABS wheel-speed sensor connector.
3. Using an oscilloscope, inspect voltage pattern for

distortion and noise by rotating each wheel.

•

If there is distortion or noise, inspect the ABS
sensor rotor.
