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.
