* Perform testing of the above steps 2-8 for each wheel. Sequence is as follows: left front right front left
rear right back.
* If result of one of the above steps is different from the result in normal condition, it shows that corresponding
actuator fails to work normally, please check corresponding actuator.
* Here as long as "return " position appears on the screen, it may finish the testing via "ESC " key and returns
to function menu.VI. Troubleshooting quick index tableMK-60 ABS system - ABS Diagnosis5-100Diagnostic

Note: fault diagnosis instrument function "03 hydraulic control unit diagnosis" is used for this inspection.MK-60 ABS system -ABS System Check5-115Key switch position Operation Standard value RemarksIV ABS work inspection1. Check wheel speed sensor output voltage
a. Check whether gap between wheel speed sensor and gear ring meets standard value or not
For standard value of front wheel, see installation drawing of front wheel sensor
For standard value of rear wheel, see installation drawing of rear wheel sensor
b. Jack up wheel, loosen manual brake
c. Remove ABS wiring harness, measure at wiring harness socket connector

Section3 Removal and InstallationI. Precautions for removal and installation1. Firstly use diagnostic instrument to find out source of trouble, then repair.
2. Repair front prior use excluding mineral oil of detergent will surface clean Neatness ; repair when should note
before repair, use detergent without mineral oil to wipe off surface; pay attention to cleaning during repair, only
use rag without wool to wipe removed components.
3. Only use original factory spare parts, and new spare parts could only be unpacked just before installation.
4. Return liquid pump motor and hydraulic controller (HCU) is integrated structure, can not be separated.MK-60 ABS system -ABS System Check/ Removal and Installation5-116 d. Rotate the wheel at speed of about 1 / 2 turns per second, use multimeter or oscillograph to measure output
voltage
Terminal 45-46
Terminal 33-34
Terminal 37-36
Terminal 42-43
Output voltage

When use multimeter for measurement
See front wheel sensor drawing for front wheel.
See rear wheel sensor drawing for rear wheel

When use oscillograph for measurement
See relevant standard for front wheel.
See relevant standard for rear wheel.
e. If output voltage is not in above-mentioned range, the cause might be the following:

Air gap between sensor and pulse ring is too large.

Sensor fails.

Check sensor resistance value (1. 0 - 1. 3 k ohm).

Take four points on pulse ring to check air gap between pulse ring and wheel speed sensor (pulse ring
distortion).
2. Check hydraulic pressure unit HCU
a. Jack up vehicle to confirm that wheel may rotate freely.
b. Release manual brake.
c. After connecting fault diagnosis instrument, turn ignition switch to ON, here it is not necessary to start up
engine.
e. Check with reference to hydraulic control unit diagnosis.
Note: when connect or remove fault diagnosis instrument, ignition switch must be in OFF position
