4. REMOVAL OF CALIPER ASSEMBLYM?dGSAP
(1) Remove the lock pin, rotate the caliper assembly
upward, then remove the caliper assembly and secure
it with wire, etc.
Caution
The lock pin has a special grease applied to it, so be
sure not to wipe it off, and ensure that the lock pin
stays clean.

(2) After removing the caliper assembly, cover the guide pin with a cloth, etc.
8. REMOVAL OF PROPELLER SHAFT’ INSTALLATION BOLT AND NUT
Place mating marks on the differential carrier companion
flange and the propeller shaft flange yoke.
NOTE
The mating marks should be used as a reference for
re-installation.
9. REMOVAL OF SELF LOCKING NUT
(1) Before removing the self locking nuts, support the differential case with a transaxle jack.
(2) Remove the self locking nuts.
12. REMOVAL OF PARKING BRAKE CABLE AND REAR
SPEED SENSOR INSTALLATION BOLT
(1) Lower the transaxle jack slightly.
(2) Remove the parking brake cable and the rear speed sensor installation bolts.
NOTE
The task may be made easier by increasing the gapbetween the body and the crossmember.

16. REMOVAL OF REAR SUSPENSION ASSEMBLY
(1) Supporting the rear suspension assembly with a trans-
mission jack, move it toward the rear (in the direction of
the fuel tank).
(2)
Graduallyibwer the transmission jack, avoiding contact
with the stabilizer bar and the propeller shaft.
Caution
1. Ensure that the propeller shaft does not bend
greatly.
2.Ensure that the liibro joint does not receive any
shock.
NOTE
The lowering of the rear suspension assembly from the
transmission jack requires three individuals due to the
amount of weight being handled (one on the differen-
tial, and one on either side of the lower arm).
(3) In order to protect the rear suspension assembly dust shield, support the lower arm ball joint with a wooden
block.

POINTS IN WAVEFORM MEASUREMENT
3. Manually turning the wheel to be measured by
l/2 to 1
turn/second, measure the output voltage with a circuit
tester or oscilloscope. Output voltage: When measured with circuit tester: 70
mV or more
When measured with oscilloscope (max. voltage): 100
mV or more
Probable causes of low output voltage
0 Speed sensor pole piece-to-rotor clearance too large
l Faulty speed sensor
4. Then, in order to observe the output state of the wheel
speed sensors, shift into low gear
(AWD vehicle) and drive
the wheels, observe the output voltage waveform of each
wheel speed sensor with an oscilloscope.
In the case of the FWD vehicle, observe the waveform with
an oscilloscope; for the front wheels, shift into low gear and
drive the wheels; for the rear wheels, turn the wheels manually at a constant speed.
NOTE
1.Waveform may also be observed by actually driving the
vehicle.
2.The output voltage is low when the wheel speed is low
and increases as the wheel speed increases.
Symptom
Too small or zero waveform amplitude Probable causes
Faulty wheel speed sensor Remedy
Replace sensor
Incorrect pole piece-to-rotor clearanceAdjust clearance
Waveform amplitude fluctuates Axle hub eccentric or with large runoutReplace hub
excessively (this is no problem if
the minimum amplitude is 100 mVor more)
Noisy or disturbed waveformOpen circuit in sensor Replace
sensor
Open circuit in harness
Correct harness
Incorrectly mounted wheel speed sensorMount correctly
Rotor with missing or damaged teeth Replace rotor
NOTEThe wheel speed sensor cable moves following motion of the front or rear\
suspension. Therefore, it is likely that it
has anopen circuit only when driving on rough roads and it functions normally \
on ordinan/ roads. It is, therefore, recommended
to observe sensor output voltage waveform also under special conditions,\
such as rough road dnvlng.

INSPECTION OF HYDRAULIC UNIT
INSPECTION BY FEEL
(1) Jack up the vehicle and support the vehicle with rigid racks
placed at the specified jack-up points.
(2) Release the parking brake and determine the drag force(drag torque) of each wheel by feel.
(3) Set the scan tool through the adapter harness
(MB991 377)
as illustrated.
(4) After confirming that the shift lever or selector lever is in the neutral position, start the engine.
The ABS warning light lights up, it goes into the scan tool mode. In the scan tool mode, ABS does not function.
