When ABS indicator lights are turned on, the ABS coontrol unit has detected a fault in the system or is faulty.
Code retrival is required to check if any trouble codes are present. If a scanner does not show any trouble codes or cannot communicate with the control unit, try a manual code retrieval.
Bridge terminal # 4 and # 9 of the OBD-II data link connector and turn the ignition switch on. Note if the ABS indicator starts blinking a trouble code.
If no trouble codes are present, the control unit could be faulty.
