HA17 Vent Right Front Spring

^ To vent the right front air spring the following action is required:

^ Release STAR test button so that it remains in up HOLD position after code 21 has been displayed for at least 5 seconds.

NOTE: As long as the STAR test button remains in the up HOLD position the right front air spring will continue to vent. When the desired amount of venting has occurred depress STAR test button so that it remains in the TEST position.

^ Did right front corner of vehicle vent down to normal ride height?

Very slowly or none at all -- DEPRESS STAR test button down so that it remains in TEST position. Then GO to HA18.

Slowly or at a normal rate -- If left front corner of normal rate vehicle also has leveling problems fix them first. Otherwise REPEAT Service Bay Diagnostics and if this problem still occurs REPLACE air suspension control module and then REPEAT Service Bay Diagnostics. Reading and Clearing Diagnostic Trouble Codes
