General information

  • Malfunction indicator lamp (MIL) will illuminate if certain faults are recorded.
  • Trouble codes can be displayed by the MIL or by using a Scan Tool connected to the data link connector (DLC).


  • Within 3 seconds switch the ignition key ON-OFF-ON-OFF-ON.
  • Count MIL flashes. Note trouble codes.
  • Each trouble code consists of two groups [1] [A].
  • The first group of flashes indicate the ‘tens’ of the trouble code.
  • The second group of flashes indicate the ‘units’ of the trouble code.
  • A short pause separates ‘tens’ and ‘units’ [1] [D].
  • A long pause separates each trouble code [1] [E].
  • For example: Trouble code 44 displayed [1]
  • End of test sequence indicated by trouble code 55.
  • Trouble codes can also be displayed by using a Scan Tool connected to the data link connector (DLC):
o Ram Pickup [2]
o Ram Truck [3]


  • Ensure ignition switched OFF.
  • Disconnect battery ground cable for at least 30 seconds.
  • Reconnect battery ground cable.
  • Repeat accessing procedure to ensure no trouble codes remain in ECM fault memory.
NOTE: Disconnecting battery ground lead may also erase memory from electronic units, such as radio.
  • Trouble codes can also be erased by using a Scan Tool connected to the data link connector (DLC).
