SUBJECT:

Vehicle Remains at Raised Level and / or Hard Suspension Dampening Setting

If you receive customer reports in the above model vehicles of the following Airmatic or Active Body Control (ABC) conditions listed below, this may be caused by an incorrectly coded Central Gateway.

^ Suspension remains at a raised level.

^ Hard suspension dampening setting.

^ LEDs are illuminated within the level control and dampening setting switches.

Note:
This condition is not the result of a suspension component. Parts replacement is not necessary.

Perform the following to resolve.

1. Using STAR Diagnosis navigate to the following menus: Body --> CGW-Central Gateway --> Control Unit Adaptation --> Read Coding & Change If Necessary --> Series & Engine Version.





2. Within the "Series & Engine Version" screen (Figure 1), select Version Vehicle Model".





3. Once within the "Version Vehicle Model" screen, select the correct coding (W220: 02/X) from the drop-down menu (Figure 2) and confirm with F3.

4. Disconnect STAR Diagnosis and verify proper functionality of suspension level control and dampening switches.

Note:
With the introduction of modification year 2003, new "push-type" switches have been used. If the Central Gateway is coded incorrectly to the old vehicle model version, it only recognizes the ON signal from the level control or dampening setting switches, consequently the vehicle remains at the high suspension level and or hard dampening setting.
