MITSUBISHI ENDEAVOR 2004 Service Repair Manual

3. Manually turn the wheel to be measured 1/2 to 1 turn/second. Measure the
output voltage with a voltmeter or oscilloscope.
Output voltage:
Minimal voltmeter reading: 42 mV Maximum voltmeter reading: 300 mV Minimal oscilloscope reading: 120 mV Maximum oscilloscope reading: 600 mV
Probable causes of low output voltage Wheel speed sensor pole piece-to-Wheel speed rotor clearance too large Faulty Wheel speed sensor
4. To observe the waveform with an oscilloscope: Front Wheels: Shift into "D" range and drive the wheels. Rear Wheels: Turn the wheels manually at a constant speed NOTE: Check the connection of the sensor harness and
connector before using the oscilloscope.
NOTE: The output waveform is low when the wheel speed is
low. Similarly, it will be higher as the wheel speed
increases. Waveform may also be observed by driving
the vehicle.

HYDRAULIC UNIT CHECK Required Special Tools:
MB991958: Scan Tool (MUT-III Sub Assembly)
MB991824: Vehicle Communication Interface (V.C.I.) MB991827: MUT-III USB Cable MB991910: MUT-III Main Harness A
NOTE: The Wheel speed sensor cable moves in relation to motion
of the front or rear suspension. Therefore, it is likely that it
has an open circuit only when driving on rough roads but it
functions normally when driving on smooth roads. It is
recommended to observe sensor output voltage waveform
also under special conditions, such as driving on a rough
road.

1. Jack up the vehicle. Then support the vehicle with rigid racks at the specified
jack-up points or place the front or rear wheels on the rollers of the braking
force tester.
2. Release the parking brake, and feel the drag force (drag torque) on each road
wheel. When using the braking force tester, take a reading of the brake drag
force.
3. Connect scan tool MB991958 to the data link connec
tor. CAUTION:
The roller of the braking force tester and the tire
should be dry during testing. When testing the front brakes, apply the parking
brake. When testing the rear brakes, stop the
front wheels with chocks.
CAUTION: To prevent damage to scan tool MB991958,
always turn the ignition switch to the
"LOCK" (OFF) position before connecting or
disconnecting scan tool MB991958.

4. After checking that the selector lever is in "P" range, start the engine.
5. Select "Interactive Diagnosis" from the start-up screen.
6. Select "System Select."
7. Choose "ABS/ASC/ASTC" from the "CHASSIS" tab.
8. Select "Actuator Test" from "ABS/ASC/ASTC" screen

9. Choose an appropriate item for hydraulic unit check.
NOTE: The TCL/ASC system will switch to the scan tool mode
and the ABS warning light, TCL/ASC indicator and TCL
OFF indicator will illuminates.
NOTE: When the ABS and TCL/ASC has been interrupted by
the fail-safe function, scan tool MB991958 actuator
testing cannot be used.

10. Turn the wheel by hand and check the change in braking force when the brake
pedal is depressed. When using the braking force tester, depress the brake
pedal until the braking force is at the following values, and check that the
braking force changes to the brake drag force reading taken in step 2 when the
actuator is force-driven. The result should be as shown in the diagram above.

11. If the result of inspection is abnormal, repair according to the Diagnosis Table
below.

12. After inspection, disconnect scan tool MB991958 immediately after turning the
ignition switch to the "LOCK" (OFF) position.
IN THE EVENT OF A DISCHARGED BATTERY If the engine is started using a booster cable when the battery is completely flat, and
the vehicle is then driven without waiting for the battery to be recharged, the engine
may misfire and it may not be possible to drive the vehicle. This is because the ABS
consumes a large amount of current when carrying out its initial checks. If this
happens, recharge the battery fully.
WARNING:If the ABS is not operating, the vehicle will be
unstable during braking, Do not drive the vehicle
with the TCL/ASC-ECU connector disconnected or
with the TCL/ASC not operating for any other
reason.

1. Park the vehicle on a level surface.
2. Connect scan tool MB991958 to the data link connec
tor. CAUTION: If the work below is done, finally calibrate the G and
yaw rate sensor. This is necessary because the
TCL/ASC-ECU should update the G and yaw rate
sensor neutral point.
G and yaw rate sensor replacement ASC-ECU replacement
CAUTION: To prevent damage to scan tool MB991958,
always turn the ignition switch to the
"LOCK" (OFF) position before connecting or
disconnecting scan tool MB991958.
