connector terminals No. 9 and 10. See Fig. 2. If there is continuity,
switch is okay. If continuity does not exist, check wiring. If wiring
is okay, replace switch, and retest.
Right Rear Wheel Speed Sensor Resistance Test
Turn ignition off. Using an ohmmeter, measure resistance
between ECU connector terminals No. 4 and 22. See Fig. 2. If
resistance is 800-1400 ohms, go to next test. If resistance is not as
specified, check resistance at right rear wheel speed sensor. If
resistance is correct, repair wiring and retest. If resistance is not
correct, replace wheel speed sensor and retest.
Left Rear Wheel Speed Sensor Resistance Test
Using an ohmmeter, measure resistance between ECU connector
terminals No. 6 and 24. See Fig. 2. If resistance is 800-1400 ohms, go
to next test. If resistance is not as specified, check resistance at
left rear wheel speed sensor. If resistance is correct, repair wiring
and retest. If resistance is not correct, replace wheel speed sensor,
and retest.
Right Front Wheel Speed Sensor Resistance Test
Using an ohmmeter, measure resistance between ECU connector
terminals No. 7 and 25. See Fig. 2. If resistance is 800-1400 ohms, go
to next test. If resistance is not as specified, check resistance at
right front wheel speed sensor. If resistance is correct, repair
wiring and retest. If resistance is not correct, replace wheel speed
sensor and retest.
Left Front Wheel Speed Sensor Resistance Test
Using an ohmmeter, measure resistance between ECU connector
terminals No. 5 and 23. See Fig. 2. If resistance is 800-1400 ohms, go
to next test. If resistance is not as specified, check resistance at
left front wheel speed sensor. If resistance is correct, repair
wiring, and retest. If resistance is not correct, replace wheel speed
sensor, and retest.
Right Rear Wheel Speed Sensor Shielding Resistance Test
Using an ohmmeter, measure resistance between ECU connector
terminals No. 1 and 4. See Fig. 2. If resistance is 20,000 ohms or
more, go to next test. If resistance is less than 20,000 ohms, check
shielding wire for damage. Replace harness if damage is found and
retest.
Left Rear Wheel Speed Sensor Shielding Resistance Test
Using an ohmmeter, measure resistance between ECU connector
terminals No. 1 and 6. See Fig. 2. If resistance is 20,000 ohms or
more, go to next test. If resistance is less than 20,000 ohms, check
shielding wire for damage. Replace harness if damage is found and
retest.

terminals No. 1 and 7. See Fig. 2. If resistance is 20,000 ohms or
more, go to next test. If resistance is less than 20,000 ohms, check
shielding wire for damage. Replace harness if damaged, and retest.
Left Front Wheel Speed Sensor Shielding Resistance Test
Using an ohmmeter, measure resistance between ECU connector
terminals No. 1 and 5. See Fig. 2. If resistance is 20,000 ohms or
more, go to next test. If resistance is less than 20,000 ohms, check
shielding wire for damage. Replace harness if damaged, and retest.
ECU Relay Resistance Test
Using an ohmmeter, measure resistance between ECU connector
terminals No. 1 and 8. See Fig. 2. If resistance is 50-100 ohms, go to
next test. If resistance is not as specified, check wiring. If wiring
is faulty, repair and retest. If wiring is okay, replace relay and
retest. See Fig. 3.Fig. 3: Locating Relays

ABS Main Valve Resistance Test
Using an ohmmeter, measure resistance between terminals at
ABS main valve terminals. See Figs. 1 and 4. If resistance is 2-5
ohms, ABS main valve is okay. If resistance is not 2-5 ohms, replace
hydraulic modulator.

Connect a jumper wire ECU between ECU connector terminals No.
2, 16 and 35. See Fig. 2. Depress brake pedal. Left front wheel should
be locked up. Turn ignition on. Left front wheel should rotate. If
wheel does not rotate, replace hydraulic modulator. Turn ignition off.
REMOVAL & INSTALLATION
HYDRAULIC MODULATOR/PUMP
Removal & Installation
1) Depressurize brake system. See DEPRESSURIZING BRAKE
SYSTEM. Disconnect negative battery cable. Unplug all electrical
connectors from hydraulic modulator/pump. Identify and disconnect all
hydraulic lines from hydraulic modulator/pump. Plug all line openings.
2) From inside passenger compartment, remove push rod clevis
pin. Remove hydraulic modulator/pump retaining nuts. Remove hydraulic
modulator/pump. To install, reverse removal procedure. Tighten all
fittings to specification. See TORQUE SPECIFICATIONS table. Bleed
brake system. See BLEEDING BRAKE SYSTEM.
WHEEL SPEED SENSORS
NOTE: To protect magnetic part of sensor, always leave new wheel
speed sensor in special packaging until ready for
installation.
Removal & Installation
Remove bolt retaining wheel speed sensor. Unplug connector.
Remove wheel speed sensor. To install, apply Lubricant (G-000-650) to
sensor. Install sensor, and tighten retaining bolt to 84 INCH lbs. (10
N.m).
