Notice
1. Work must be started 60s after the negative (-) terminal cable is detached from battery. The detached
negative (-) terminal cable shall be protected with insulating tape for insulation.
2. Never attempt to dismantle or repair an ECU. If there is any trouble, replace the ECU with a new one.
3. Prevent the ECU from shock or vibration. If pitting, crack or distortion is found, replace the ECU with a
new one.
4. Every time an airbag is deployed, the ECU shall be replaced with a new one.
5. When disassembling or maintaining the parts around ECU, attention must be given to avoid contacting the
ECU. 2. Removal procedures:
(1) Remove the miscellaneous box in the middle consoce.
(2) Remove the connectors to SRS ECU.
(3) Remove ECU.
3. Installation procedures:
(1) Install ECU.
(2) Install the connectors to SRS ECU.
(3) Install the miscellaneous box in the middle consoce.
(4) Connect negative (-) terminal cable of the battery.
4. Key points for Installation:

If the ECU cannot be installed correctly, the airbag will not act normally.
5. Check
a. ECU case for pitting, crack and distortion
b. The connector for damage and distortion.Notice
If pitting, crack or distortion is found on an ECU, replace it with a new one.VII. Airbag assembly & clock spring1.Removal and Installation of driver airbag and clock spring
Operations prior to removal
(1)Take out the ignition key after the steering wheel and front
wheel are adjusted to straightforward direction.
(2)Remove negative (-) terminal cable from the battery.
Removal procedures of the driver airbag assembly:
(1) Unscrew the screws of the two sides, see fig.15-65SRS (Supplemental Restraint System)-SRS-General Information (2) Check after installation.
a. Turn the ignition switch ON.
b. The warning light goes on within 4s, and then goes out.
(3) If the light doesn't go out, check the trouble and eliminate it.
For other ECU inspections, see Troubleshooting.
fig.1

1) Disconnect the positive (+) and negative (-) terminal cables from the battery and remove the battery from
the vehicle.Notice
Work must be started 60s after removal of the battery.Notice
When the connector is not connected, the terminals of the driver airbag assembly will be short circuited
automatically, preventing the airbag from being deployed unexpectedly. If the airbag is deployed unexpectedly,
the deployed surface should face up. It should be kept on a flat surface without any other items on it. 2) The airbag assembly shall be deployed according to the following procedures.
Driver airbag assembly
a. Remove the driver airbag assembly from the vehicle.
b. Prepare two 6m plus wire harnesses for deployment, connect
the other two ends to avoid unexpected deployment in case
of static electricity (see the figure below).Notice
The above-mentioned procedures can prevent the unexpected deployment due to static electricity and shall
therefore be performed strictly.Deployed Harness

d. Cut off the wire harnesses of the driver airbag assembly and
connect them with the two wire harnesses for deployment,
and make sure to wrap up the connecting location with
insulating tape for insulation (see the figure on the right).
f. Pass the deployment wire harness of the driver airbag
assembly through an old tire with rim, and fix upwards the
driver airbag assembly by means of the wire connected to
the bolts, etc (see the figure on the right). e. Install the unused bolts to the inside bolt of the driver airbag assembly,and tie a thick metal wire securing
the wheel rim.5-70SRS (Supplemental Restraint System)-

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

firstly confirm whether voltage of storage battery is normal, when conduct motor drive test, vehicle must be in idle
state.MK-60 ABS system -ABS System Check5-103Fault code is 01276 1
[Description ] When vehicle speed exceeds 20 km/h, ABS ECU monitors that
motor can not work normally, it will record this fault code
[Prompt ] When this fault appears, wiring harness connection between motor
and ECU may get loose. Use hydraulic pressure unit functional
testing of fault diagnosis instrument to drive motor for this test.Possible cause

Power supply is discon-
nected or earthed

Motor wiring harness gets
loose

Motor is damaged
Pull out motor wiring harness plug, connect
battery power source directly to motor plug, see
whether motor works or not?
Check safety wire and ABS ECU joint
Connect motor wiring harness
Turn ignition switch to ON position
Eliminate fault code
Use fault diagnosis instrument to conduct
hydraulic control unit diagnosis
Whether fault recurs

[Description ] when open circuit cannot be detected, there is no signal output
even if vehicle speed reaches above 20 km/h, this fault code
will appear.
[Prompt ] It is probably because that sensor is not mounted, sensor coil or
wiring harness is shorted, air gap between sensor and gear ring is
too large or gear ring is damaged.Possible cause

Sensor is not mounted

Sensor coil or wiring har-
ness is shorted

Air gap between sensor
