With Air Suspension

1. Run the Auto Test.

2. Carry out the manual input test as follows:

3. A DTC 12 will be displayed at the end of the Auto Test only if everything checked to this point is functional.

4. After DTC 12 (or DTC 13) is displayed, the air suspension control module is ready to check for manual inputs. The manual inputs check the steering sensor and door courtesy lamp switch circuits. During the manual test, the air suspension control module continually monitors the door and steering sensor circuits for activity. To pass the manual test, the air suspension control module must detect that four doors have been opened and closed, and the steering wheel has been turned at least one quarter turn in each direction. After the manual test, the Super Star II Tester button must be toggled or the air suspension control module will continue to monitor the manual input tests indefinitely. Either a DTC 11 (air suspension OK) or other DTCs will be displayed at this time.

5. After the auto and manual input tests, the DTCs will be displayed automatically. Each DTC detected will be displayed for about 15 seconds. The code display will continue until all DTCs have been displayed. The display will repeat the OTC until Super Star II Tester button is released (up). Document all DTCs.
