3 Code 

00283，00285，00290，00287 Possible 

causes 

［Note］When vehicle speed is over 20km/h，code will be set if sensor signal 

is not within the gap specification.   

［Method］Code may be set for sensor coil or wiring harness intermittent 

poor contact or short, weak sensor signal caused by big gap between sensor 

and gear ring or defective gear ring teeth.. 

● sensor coil harness intermittent 

poor contact or short. 

●big or small air gap between sensor 

and gear ring 

●damaged gear ring teeth 

big bearing gap 

defective ABS ECU

4 Code 

00283，00285，00290，00287 Possible 

causes 

［Note］Code will be set when sensor has recognizable open or short 

problem. 

［Method］  Poor sensor connection, coil or wiring harness short, defective 

sensor signal circuit in ABS ECU。 

●Sensor connector or coil open 

●Sensor coil short 

●Sensor connector or harness short 

to ground or power 

●Defective ABS ECU sensor signal 

circuit.

Does problem appear again?

No 

Go to INTERMITTENT

FAULT DIAGNOSTIC 

YES

Check electrical harness between 

ABS ECU and sensor 

Remove ABS ECU connector. 

Check resistance between following

terminals. Is resistance within

1.0~1.3 KOhm? 

 

Wiggling sensor wiring harness and

connector while mearing resistance.

LF: 1-2 

RF: 19-20 

LR: 5-6 

RR: 22-23 

 

Normal

Code 01044 

Possible causes 

［Note］  When ECU software programming code is not consistent with ABS 

harness pin, code will be set. 

●Pin connection error in ABS harness. 

●ABS ECU programming error. 

 

 

Check if ABS ECU software programming correct

using scan tool. 

Correct value: 

01901 for SQR 7160 and SQR 7160L 

NO 

Reprogramme

Code 00668 

Possible causes 

［Note］ 

When no voltage or high voltage at terminal 30, code is set。 

●  Blown ABS system fuse 

●  High or low battery voltage 

● defective ABS electrical harness 

connector 

● defective ABS ECU 

 

 

 

 

Check ABS system 30A fuse 

Normal 

Not normal

Replace fuse

Not normal 

Repair connector 

Normal

Retry.Does problem reoccur?

NO

YES

Disconnect ABS electrical harness

and ECU. Turn ignition to ON

position.  

Measure voltage between

terminals: 

8 and 9: 9.5-16.5V 

24 and 25: 9.5-16.5V 

8 and 4: 9.5---16.5V 

Normal
