General information

  • Engine control module (ECM) incorporates self-diagnosis function.
  • Malfunction indicator lamp (MIL) will illuminate if certain faults are recorded.
  • ECM operates in backup mode if sensors fail, to enable vehicle to be driven to workshop.

Accessing

  • Trouble codes can only be displayed by using a Scan Tool connected to the data link connector (DLC):
o Range Rover -> 2001 – fascia, passenger’s side [1].
o Range Rover 2001 ->  fascia, driver’s side [2]
o Range Rover Sport 2005 ->/Discovery/LR3 – fascia, driver’s side [3].
o Freelander -> 2001 – under fascia, passenger’s side [4].
o Freelander 2001 ->under fascia, driver’s side [5]

Erasing

  • After the faults have been rectified, trouble codes can only be erased by using a Scan Tool connected to the data link connector (DLC)
