diagnosis" , proceed according to the following steps.MK-60 ABS system -
ABS Diagnosis5-99I. Check ABS warning lamp1. Check whether ABS warning lamp illuminates in the following way
a. Ignition switch turns to ON, ABS warning lamp illuminates for approximately 1.7s then goes out.
b. If it is not the above-mentioned case, it shows that there is fault, please check fault code.
c. If warning lamp does not illuminate at all, refer to trouble check list without fault code.II. Reading of information state After power on fault diagnosis instrument, turn ignition switch to "ON " position, select function menu item
01, press OK for confirmation, the screen will display the following status information
1. E. g. ECU drawing number and version number:
ABS MK60 IE
2. Code 040907III. Read and eliminate fault code1. After select "02 read fault code" in function selection menu, firstly display total number of fault, if there is no
fault code, display no fault code. Now, press OK key to turn page, look down for fault code and its description.
There is generally P or O before fault code, which represents that this is a persistent fault or a occasional fault.
Persistent fault always exists, while occasional fault may be eliminated, only when run on real vehicle, might it
appear again.
Note:
Read fault code function can not be exited in midway, only after all fault codes are turned over, could it return
to function menu.
Eliminate fault code
2. In function selection function menu 05, press OK key to eliminate fault code, if fault code cannot be eliminated,
it shows that this is a occasional fault, could be detected again only when the vehicle is actually running.IV. Display mode of malfunction codeDisplay code
No fault code

* 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

VI. Filling brake fuid and bleadAfter replace HECU, besides filling and blead as per routine brake system, also blead the secondary circuit of
HECU. Steps are as follows if fault diagnosis instrument is used for operation:MK-60 ABS system -Removal and Installation5-119Perform charging blead according to routine brake system until no bubble
appears in transparent rubber tube

Flashing way of malfuntion code 17 for O2 sensor (3) Each fault code will blink for three times, interval time is 3s, after blinking for the third times, after an
interval of 3s, next fault code will blink. After blinking of all fault codes is finished, they will blink from begining
again. The following diagram shows engine fault warning lamp blinking mode for oxygen sensor fault code 17.5-127Terminal No. Terminal definition

operate tester, if tester displays that communication is not possible, the vehicle or tester fails.
Inspection diagnosis
1. Check engine fault warning lamp
(1) When ignition switch is turned to ON position and engine does not run, engine warning lamp on
instrument should illuminate.
(2) When engine runs, engine fault warning lamp should go out. If it still illuminates, diagnostic system
detects system fault or abnormity.
2. Use handheld tester to check diagnostic code
(1) Connect handheld tester according to corresponding pin.
(2) Turn ignition switch to ON position, turn on main switch of handheld tester.
(3) Use handheld tester to detect and check diagnostic code, refer to fault diagnostic code table. (For
operation of handheld tester, see instruction manual of handheld tester)
3. Engine fault warning lamp displays fault code through blinking code, so professional may make fault
judgment in case of emergency.
(1)Turn ignition switch to ON position.
(2) Short signal pin (9#) and negative pole (4#) for more than 2. 5s,then disconnect them,detection fault lamp
on dashboard will blink the faults in fault code according to their occurrence sequence.See from terminal outlet
endConnect in jump way over 2.5s and
disconnect

Electric A/D switchChapter 11 Rear Parking Radar SystemI. System principle Reversing radar system mainly adopts ultrasonic ranging technology, utilizes piezoelectric property of
transducer (ultrasonic sensor), excites piezo sheet with voltage with frequency of 40KHZ intermittently, this piezo
sheet is then converted from electric energy to mechanical energy and sent out. When emitted sound wave contacts
object, it will reflect weak sound wave energy to transducer according to sound wave reflection principle, i. e.
convert received weak acoustic vibration signal to electrical signal, after signal amplification processing, it is
transmitted to microprocessor to calculate the distance between vehicle and this object and display the distance.
Then microprocessor determines whether to give caution remind for dangerous object according to varying
degrees.II. Circuit diagramPlease Refer to "MK WIRING DIAGRAM"

III. Fault diagnosis 1. During detection, if there is no sound or display screen does not illuminate, please detect whether polarity
of power supply is connected in a wrong way, whether power cord is connected, whether supply voltage 9V,
whether display joint is inserted properly.
2. If clobber "0.0" or constant ringing occurs, please exit reverse gear, engage reverse gear again. If the
above symptom still exists, it may be deemed that principal machine is damaged, and should be replaced
completely.
3. If certain value is displayed, while there is no evident barrier at right ahead of probe. Prominence on or rear
might be detected (such as license plate, bumper bar etc). please check whether direction axis of the probe is
correct, horizontal axis of the probe should slightly upwarp.
4. When accelerating, the installed display shows irregular disordered frame, circuit interference might occur,
check earth wire of reversing radar.IV. Installation of reversing radar 1. Reversing radar system consists of reversing radar principal machine, reversing radar display screen, wiring
harness, buckle and reversing radar probe etc.Rear Parking Radar System-
