Circuit Description

WARNING: This page is about a different car, the 2007 Hummer H2. However, it is still accessible from the selected car via links, so may be relevant.

The air suspension module monitors the trim height calibration procedure. When the calibration procedure is activated the vehicle exhaust down to rest on a chassis support at a predetermined height. When no further height change is detected, the height sensor readings are verified to be within 2.06-2.88 volts. If there are no errors then the new trim height is accepted. If the air suspension module detects any errors in the trim height calibration procedure then the new trim height is not accepted and a DTC is set.
