General information

  • 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 and erasing

  • The engine control module (ECM) fault memory can only be accessed and erased using diagnostic equipment connected to the data link connector (DLC):
o S-Type/XJ/XK 1
o X-Type 2
