Initialization procedure for auto-leveling control module
• An initialization procedure for the auto-leveling control module has been added. When
this procedure is activated, the auto-leveling control module detects the height of the
unloaded vehicle via the signal from the auto-leveling sensor and stores it as a reference
value in the control module memory.
• The auto-leveling control module must be initialized when any of the following
procedures has been performed:
– Front combination light replacement
– Auto leveling control module replacement
– Auto leveling sensor removal/installation
– Instrument cluster replacement
– PJB replacement
– Replacement of suspension components or work that effects vehicle height
• In order to activate the initialization procedure for the auto-leveling control module,
connect M-MDS to the vehicle and select the option Toolbox→Electrical→Exterior
Lighting→Headlamp→Auto-leveling Sensor Re-zero Procedure.
NOTE: In case the initialization procedure using M-MDS is not possible, it can also be
performed by connecting terminal B in the DLC-2 to ground (refer to the workshop
manual for the detailed procedure).
