• One of the following DTCs may be stored in the level control system module, J197 (address word 34):
• DTC 0453 (restricted function through excess temperature).
• DTC 1583 (leak in the system recognized).
• DTC 1770 (sender for compressor temperature of self-leveling control G290).
• DTC 1772 (signal cable of pressure sender for self-leveling control G291).
• DTC 2645 (valves for self-leveling control).
• DTC 2646 (plausibility of self-leveling control).
Technical Background
Because of poor performance or failure of the air suspension compressor, the vehicle ride height cannot be
adjusted. As a safeguard, the control module will lower the vehicle to the lowest position and illuminate the
warning light. Drivability is not affected.
Production Solution
Not applicable.

Tip: See the current flow diagram for the location of the J403 relay for the air supply unit and the location of
the air compressor (air supply unit).
1. Check the function of the air compressor by supplying it with direct current. Determine if the air compressor is
operating correctly and sounds normal, if it is unusually noisy, or if it is not working at all.
2. Check relay J403 by opening the relay and comparing it to the images below:
If the relay exhibits any of the conditions A – C below, replace both the air compressor and the relay,
even if the air compressor sounds normal.
A) Strong erosion of both contacts (Figure 1, Figure 2).
Figure 1. Strong erosion of both contacts.
Figure 2. Strong erosion of both contacts.
