SUBJECT:
Model 211.065/070/076, up to VIN A255298
Equipped with Airmatic Suspension (sales code 489)
Vehicle Level Decreases at Front Axle
If you receive customer reports in the above model vehicles of low ride height at the front axle after the vehicle has been parked at cold (15° F or colder)
ambient temperatures, replace only the affected suspension air strut. Reference WIS document AR32.25-P-1017TA.
NOTE:
A certain amount of suspension drop due to thermal contraction is normal and should not be regarded as a malfunction. Approximately 30 mm of
suspension dropping in cold temperatures is within design parameters.
The following fault codes may be stored within the Airmatic control module:
-
5501-Event: Critical vehicle level at rear axle
-
5500-Event: Critical vehicle level at front axle
-
5507-Suspension strut is implausible
NOTE: In extreme cases the Airmatic compressor will not activate to raise the vehicle. The Airmatic compressor is not defective, and must not be
replaced. The compressor is not actuated due to insufficient residual pressure in the suspension struts. In such cases the compressor must be
actuated with STAR Diagnosis.
