tion. When servicing is done, use the “Drive Parking Brake To Latching Position” in the Control I/O
menu of your IIDTool and verify the parking brake functionality.
Select Normal or Service position (L405-13, L494-14, L538-11, L359 2013+)
This routine will allow servicing the rear brakes. For L320-05 et L322-06, the function is located in the
control IO menu.
Usage
Select Service position when servicing the brakes and Normal when nished.
Preparation
• Disengage the parking break
• The ignition must be turned ON without the engine running.
Note: On vehicles using the old nomenclature, Latching position is the equivalent of Normal position
while Mounting is the Service position.

Note : For the service reminder reset routine, see Instrument Pack ECU (except for L316-12 and
L359 2013+).
Clear Adaption Values (Diesel : L316, L494-2016 3.0L, Petrol : L322, L319, L320, L359*,
L405-13, L494-14)
This routine resets the adaption statistics back to factory default. In other words, after the engine adap-
tions are cleared, the engine ECU will have to “learn” the dierent sensors behaviors and compensate
accordingly.
*on request only, requires Renew security afterwards.
Usage
The clear adaption routine is necessary when, for example but not limited to, one of these components
is replaced:
• Idle speed control valve. Over a period of time, the engine ECU adapts the position it sets the
idle speed control valve relative to the engine temperature, load and idle speed control valve
itself.
• Throttle position sensor. The engine ECU “learns” the closed position voltage delivered by the
throttle position sensor.
• Heated oxygen sensors and airow sensor. The engine ECU will monitor and compensate for
deterioration of the Oxygen, MAF (Mass Air Flow) and other sensors over a period of time. It will
also monitor the current correction associated with these sensors.
