I. DTC Problem Inspection Table
1 DTC 01276
[De s cription]
When the vehicle speed exceeds
20km/h, ABS ECU detects that the motor can not
operate normally and record this DTC.
[Hint]
When this problem occurs, one of the
possible causes is that the wire harness between
the motor and the ECU is disconnected. Use the
scan meter to perform the test by activating the
HCU function to drive the motor.
Note: If the Battery is excessively discharged, the motor will not be driven, therefore you must
check that the battery voltage is normal before performing the motor driving test. The vehicle
must be stationary during the test.
Remove the motor wire harness connector, connect
it to the Battery to see whether the motor operates?
