STEP 2. Check the harness wires between the ABS-ECU
connector A-02 and the wheel speed sensor <front: LH>
connector A-22.
NOTE: After inspecting the intermediate connector C-06,
inspect the wires. If the intermediate connector C-06 is
damaged, repair or replace it. Refer to GROUP 00E, Harness
Connector Inspection
. If the connector has been
repaired or replaced, go to Step 8.
Q: Is any of the harness wires between the ABS-ECU
connector A-02 and the wheel speed sensor <front: LH>
connector A-22 damaged?
YES : Repair it and go to Step 8.
NO : Go to Step 3.
STEP 3. Check the harness wires between the ABS-ECU
connector A-02 and the wheel speed sensor <front: RH>
connector A-37.
Q: Is any of the harness wires between the ABS-ECU
connector A-02 and the wheel speed sensor <front: RH>
connector A-37 damaged?
YES : Repair it and then go to Step 8.
NO : Go to Step 4.

STEP 4. Check the harness wires between the ABS-ECU
connector A-02 and the wheel speed sensor connectors D-
08 <rear: RH> or D-09 <rear: LH>.
NOTE: After inspecting the intermediate connector C-90, C-94
or D-16, inspect the wires. If the intermediate connector C-90,
C-94 or D-16 is damaged, repair or replace it. Refer to GROUP
00E, Harness Connector Inspection
. If the connector
has been repaired or replaced, go to Step 8.
Q: Is any of the harness wires between the ABS-ECU
connector A-02 and the wheel speed sensor connector
D-08 <rear: RH> or D-09 <rear: LH> damaged?
YES : Repair it and then go to Step 8.
NO : Go to Step 5.

STEP 5. Check each wheel speed sensor output voltage.
Refer to
.
Output Voltage:
•
When measured with a voltmeter: 42 mV or more
•
When measured with oscilloscope (maximum voltage): 200
mV or more
Q: Does the voltage meet the specification?
YES : Replace the hydraulic unit (integrated with ABS-ECU)
and then go to Step 8.
NO : Go to Step 6.
STEP 6. Check the wheel speed sensors or ABS rotors.
Refer to
. If there is a damage in any of the following
check items, replace the wheel speed sensor or the ABS rotor.
Check items:
•
Wheel speed sensor internal resistance
Standard value: 1.28
−
1.92 k
Ω
•
Insulation between the wheel speed sensor body and the
connector terminals
•
Toothed ABS rotor
Q: Is any of the wheel speed sensors or ABS rotors
damaged?
YES : Replace the faulty part and then go to Step 8.
NO : Go to Step 7.
STEP 7. Check the wheel bearings.
Refer to GROUP 26, Front Hub Assembly
, and GROUP
27, Rear Axle Hub
Q: Is any of the wheel bearings damaged?
YES : Replace it and then go to Step 8.
NO : Go to Step 8.
STEP 8. Check the diagnostic trouble codes.
Q: Do the diagnostic trouble code 15 reset?
YES : Go to Step 1.
NO : This diagnosis is complete.
