Risk, updating the Instrument Pack ECU
L319-04 and L320-05 :
User can choose between three firmware:
•
IPC MY07+
: IPC Model Year 2007 and up. This firmware will add the clock display on 2005-
2006 vehicles. When turning ON the headlamps on a 2005-2006 vehicle after the IPC was
updated with this firmware, the AHCM (auxiliary heater, fitted on diesel vehicles) indicator light
will turn ON. On 2007 and up vehicles, the logo for this particular lamp changed for the “head
-
lamps ON” one. On 2005-2006 Petrol vehicles only, the amber “parking brake” indicator light
replaces the “check engine” light.
•
IPC MY07+
for pre
MY07
: Model Year 2007 up firmware adapted for 2004-2006 Model Year
vehicles. This modified firmware version will also add the clock display on 2005-2006 vehi
-
cles but without any of the disadvantages found in the non-modified version described above
(
IPC MY07+
).
•
IPC pre-MY07
: This is the original firmware version found on 2005-2006 vehicles. No clock
display on this one.

Before updating this ECU, please read the following:
• Re-flashing the Instrument Pack ECU takes around one minute.
• Once re-flashing is completed, turn key to the OFF position for at least 3 minutes before starting
the engine.
• On MY07+ firmwares, the low coolant warning lamp may come on after updating because the
later firmware will react differently to the sensor input. This may be due to the coolant level being
too low or a known problem with the expansion tank float/sensor becoming less buoyant. We
strongly recommend fixing the issue but it is also possible to revert back to the earlier firmware
version.

The clock on dash is displayed in the 24-hour format only. The 12-hour format was not imple

Suspension ECU to fix this issue.
L319-10 and L320-10

On 2010 and 2011 vehicles, this function will allow updating the instrument
pack ECU software to the latest version (2012 look). Re-flashing the Instrument Pack ECU takes
