Vehicle Direction Alert Alarm Warning Module Calibration

WARNING: This page is about a different car, the 2009 Cadillac STS. However, it is still accessible from the selected car via links, so may be relevant.

To initialize the calibration, select Calibrate Module in the scan tool Module Setup menu for the Vehicle Direction Alert Alarm Warning Module. After the Calibrate Module selection has been made, operate the vehicle in the following conditions until the green indicator illuminates:

Maintain vehicle speeds of 56 km/h (35 mph) or more
Drive on clear stretch of straight road
Drive during the daytime
Ensure the road contains visible references (well defined lane markings, curbs, guard rails, fences, buildings, etc.)

When the lane departure warning system is in calibration mode, the amber light on the instrument panel cluster (IPC) will remain illuminated. When the calibration is complete, the green indicator will illuminate and the system is ready to assist. Immediately after the self calibration procedure, there may be a delay in lane crossing alerts. The lane departure warning system will run further calibration tests as the vehicle is driven in order to improve performance.

One or more of the following conditions may increase the length of time required to complete the self-calibration procedure:

Operating the vehicle at 31 to 61 km/h (19 to 38 mph)
Curves in roadway
Driving through snow or fog, driving at night, or driving directly into the sun
Bott's Dots type lane markings
Poor contrast lane markings

Conditions that will prevent completion of the self-calibration procedure:

Operating the vehicle at less than 31 km/h (19 mph)
No visible lane markings
