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.


  • Trouble codes can be displayed by using a Scan Tool connected to the data link connector (DLC): 1
o 3000GT/Diamante – [2]


  • Trouble codes can be erased by using a Scan Tool connected to the data link connector (DLC) or as follows:
  • Ensure ignition switched OFF.
  • Disconnect battery ground cable for 30 seconds minimum.
  • Reconnect battery ground cable.
  • Repeat checking procedure to ensure no data remains in ECM fault memory.

NOTE: Disconnecting battery ground lead may erase memory from electronic units such as radio.
