FX9000 User Manual
• Misfire and fuel system faults require three trips with “similar conditions”
before the MIL is turned “O.” These are trips where the engine load, RPM
and temperature are similar to the conditions present when the fault was rst
found.
Note: After turning o MIL, DTCs and Freeze Frame data will stay in
the computer’s memory.
• Erasing the DTCs from the computer’s memory can also turn o the MIL. If a
Diagnostic Tool or Scan Tool is used to erase the codes, Freeze Frame data
will also be erased.
