No.310 Malfunction codes: 00283, 00285, 00290 and 00287   

3 

The malfunction codes are 00283, 00285, 00290 and 00287 

Possible cause 

[Description] 

The malfunction code will appear if the sensor signal is out 

of tolerance when the speed is larger than 20km/h.   
[Prompt]  The probability is that the weak sensor signal is cause by the 
intermittent poor contact or the short of the sensing coil or the harness, 
damage of the tooth ring teeth and ultra large of the air gap between the 
tooth rings.   

z

 

Intermittent poor contact or short of the 
sensing coil or the harness 

z

 

Ultra big or ultra small of the air gap between 
the sensor and the tooth ring 

z

 

Damage of the tooth ring teeth 

z

 

Ultra big of the bearing clearance 

z

 

Malfunction of ABS ECU 

 

Is the sensor installation correct? 

Inspect the sensor output voltage at 
the ABS25 core socket 

Inspect each wheel sensor 

Inspect the tooth ring of each 
wheel sensor 

Inspect the wheel bearing 
clearance 

Inspect the harness between the 
sensor and ABS ECU

(electric failure)   

4 

Malfunction code: 00283, 00285, 00290 and 00287 (electric 
malfunction) 

Possible cause 

[Description] 

The malfunction code wil appear when there are failures 

such as the recognizable open circuit or short circuit existed in the 
sensor.  
[Prompt]  It is likely that the sensor is in poor contact, the coil or the 
harness is short, or there is a failure in the sensor signal treatment circuit 
in ABS ECU.   

z

 

Connector or coil of the sensor is of open circuit

z

 

The sensing coil is short 

z

 

The sensor plug, the harness, the earth or the 
power is short 

z

 

Treatment circuit of ABS ECU    sensor signal is 
out of order 

 

Inspect the corresponding sensor 
with failure 

Remove the ABS ECU plug 
Inspect if the resistence value 
between the following terminals of 
ABS ECU meets the standard 
value? 

Standard value:    1.0 ~ 1.3 k  

　

Shake the sensor harness and the 

joint simultaneously when 

measuring the resistance.   

MK20 I:   

Left front: 4 - 11   

Right front: 3 - 18   

Left rear: 2 - 10   

Right rear: 1 – 17 

MK20 I/E：   

Left front: 1 - 2   

Right front: 19 - 20   

Left rear: 5 - 6 
Right rear: 22 – 23 

 

Inspect the corresponding 
sensor plug 

Does the malfunction recur? 

Inspect the harness between 
the sensor and ABS ECU 

Refer to the gist 
of the incidental 
trouble 
maintenance 

Inspect if the harness is normal and watch if the failure will recur 

Repair the connector

No.312 Malfunction code: 01044   

5 

Malfunction code: 01044 

Possible cause 

[Description] 

The malfunction code will appear when the ECU software 

code is different from the hardware jumper connection of ABS harness. 

z

 

Error of jumper connection in ABS harness 

z

 

Error of ABS ECU code 

 

 

No.313 Malfunction code: 00668 

6 

Malfunction code: 00668 

Possible cause 

[Description] 

The malfunction code will appear when there is no 

voltage or over high voltage on the power supply terminal 30.   

z

 

Fuse of ABS system is blown out 

z

 

The battery voltage is over low or over high 

z

 

Connector of ABS harness is damaged 

z

 

ABS ECU is damaged 

 

Check if the joint of ABS harness slip stitch is 
conductive 
Joint of correct slip: see relative ABS electric wiring 
diagram 

Use the failure diagnosis instrument to check if the 
code of ABS ECU software is correct 
Correct value: see relative ABS electric wiring

7 

Malfunction code: 01130 

Possible cause 

[Description] 

The malfunction code will appear when ABS is 

interfered by the high frequency electromagnetic wave or the 

microprocessor regards the input speed signal as false.   

z

 

High frequency electromagnetic 
interference 

z

 

The sensor or the sensor harness is 

damaged 

z

 

ABS ECU is damaged 

 

Inspect 30A fuse of ABS system 

Disconnect the connection between 
ABS harness and ECU, turn the 
ignition switch to "ON" and measure 
the voltage between the following 
terminals of ABS harness 
Terminals 8 and 9:      9.5 – 16.5V 
Terminals  24 and  25: 9.5 - 16.5V 
MK20 I: 
Terminals  8 and  23: 9.5 –16.5V 
MK20 I/E:   
Terminals  8 and 4:  9.5 –16.5V
