General information

  • Malfunction indicator lamp (MIL) will illuminate or flash if certain faults are recorded.
  • ECM operates in backup mode if sensors fail, to enable vehicle to be driven to repair shop.


• Trouble codes can only be displayed by using a fJ Scan Tool connected to the data link connector (DLC):
o Bronco 1
o Econoline/Club Wagon/Escape/Expeditionl Explorer/F-Series 4.2L/4.6L/5.4L SOHC/ RangerlWindstar 2
o Aerostar/Excursion/F-Series 4.9L/5.0L/5.8L/6.8L/7.5L/7.3L Turbo Diesel 3.


• Trouble codes can only be erased by using a Scan Tool connected to the data link connector (DLC).
