DRIVE CYCLE DIAGNOSTICS
If a fault is detected in system while vehicle is in motion, RIDE CONTROL light will be activated. A maximum of 32 codes can be stored for one hour after ignition is turned off. See ELECTRONIC SUSPENSION DIAGNOSTIC CODES table.
Codes can be obtained if ignition remains off with suspension switch on. Drive vehicle for a minimum of 4 minutes at speeds greater than 15 MPH. Turn ignition off. Verify suspension switch is on. Turn off headlights (if on).
Ensure test button is in HOLD position and connect tester to air suspension diagnostic connector. See Fig. Turn tester on. Wait 5 seconds and press test button to TEST position. Within 20 seconds, SUPER STAR II tester should continuously display a code.
If Code 15 is displayed, DRIVE CYCLE DIAGNOSTICS is completed and no faults were found in system. Remove tester to exit DRIVE CYCLE DIAGNOSTICS. If any code between 40 and 71 is obtained, DRIVE CYCLE DIAGNOSTICS is completed and faults were found in system. Record all codes, and post for more help
