4. Speed Sensors

Possible Cause

4. Fault Code 00283, 00285, 00290, 00287
[Description]
This code will be displayed when open circuit or short
circuit of sensor is detected.
[Tip]
The fault may be caused by poor contact of sensor, short
circuit of sensor coil or wire harness, or problem with
sensor signal processing circuit in ABS ECU.

·

Large or medium open circuit of

sensor adapter

·

Short circuit of sensor circuit

·

Short circuit of sensor plug or wire

harness with earthproof or power

·

ABS ECU sensor signal

Yes

Check wire harness between

sensor and ABS ECU

Normal

Replace ABS ECU

Demount ABS ECU plug
and check the resistance
between following
terminals.

Standard value:1.0-1.3kΩ

Shake sensor wire harness
and adapter when
measuring resistance.

5. ABS Coding Error

Possible Cause

5. Fault Code 01044
[Description]
This code will be displayed when inconsistency
between software coding of ECU and hardware
connection of ABS wire harness is detected.

·

Wrong connection of plunger

pin in ABS wire harness

·

ABS ECU coding error

No

Recode

Check if software coding of ABS ECU is
correct with fault diagnoser
Correct value: refer to related ABS
electrical wiring diagram

Abnormal

Repair wire harness

Check plunger pin conduction in ABS wire
harness
Plunger pin connecter: refer to related ABS
electrical wiring diagram

Check battery voltage

Normal

Measure voltage between
following terminals with ABS
wire harness disconnected to
ECU and ignition switch being
“ON”.
Terminal 8 and 9: 9.5-16.5V
Terminal 24 and 25: 9.5-16.5V
MK20I/E:
Terminal 8 and 4: 9.5-16.5V

Replace ABS ECU
