NOTICE
• It is necessary to reset the ECU default value using the diagnosis tool at the time of supply pump service
replacement. In addition, the ECU has a function enabling it to learn the performance of the supply pump at the
time of ECU service replacement, so ensure sufficient time (several minutes) is available.
• When an injector is newly installed in a vehicle, it is necessary to enter the ID codes in the engine ECU using
the Diagnostic tool.
