VII. Coded Fault Checklist 

1. ABS Hydraulic Pump 

Possible Cause 

1. Fault Code 01276 
[Description]  
This code will be recorded by ABS ECU if motor malfunction is 
found when vehicle speed exceeds 20km/h. 
[Tip]  
The fault may be caused by loose wire harness connection 
between motor and ECU. Fault diagnoser may be used to drive 
the motor to test hydraulic control unit function. 

   

·

Power off or earthed 

·

Loose motor wire harness 

·

Damaged motor 

 

Note: Overdischarged battery will not be able to drive the motor, therefore 

battery voltage shall be measured before motor driving test. Motor driving test 

shall be performed with vehicle being stationary. 

 

Abnormal 

Replace hydraulic control unit 

                       

Normal 

Unplug motor wire harness and directly 
connect battery power to motor plug, check 
if the motor works 

Abnormal

       

Replace fuse or wire harness 

     

                        Normal 

 

         

                                                           

Replace ECU 

             

No

 

Check fuse and ABS ECU adapter 

Connect motor wire harness 

Ignition switch “ON” 

Clear fault code 

Diagnose hydraulic control unit with diagnoser

Dose fault reoccur? 

Yes

Refer to Incidental Fault Repair Instruction

2. Wheel Speed Sensors: 00283, 00285, 00290, 00287 

Possible Cause 

2 Fault Code 00283, 00285, 00290, 00287 
[Description]  
This code will be displayed when no open circuit is 
detected while no signal is output with the vehicle speed 
exceeding 20km/h. 
[Tip]  
The fault may be caused by missed sensor, short circuit of 
sensor coil or wire harness, oversized air gap between 
sensor and gear ring or damaged gear ring. 

·

Sensor missed when assembling 

·

Short circuit of sensor coil or wire 

harness· 

·

Oversized air gap between sensor 

and gear ring· 

·

Gear ring missed when 

assembling 

·

ABS ECU fault

 

 

No

3. Speed Sensors 

Possible Cause 

3. Fault Code 00283, 00285, 00290, 00287 
[Description]  
This code will be displayed when sensor signal exceeds 
tolerance limits with the vehicle speed > 20km/h. 
[Tip]  
The fault may be low signal caused by intermittent poor 
contact or short circuit of sensor coil or wire harness, 
damaged gear ring or oversize air gap between sensor and 
gear ring. 

·

Intermittent poor contact or short 

circuit of sensor coil or wire 
harness· 

·

Oversized or undersized air gap 

between sensor and gear ring 

·

Damaged gear ring
