Lucerne V8-4.6L (2008)
Collision Avoidance Module: Procedures
Vehicle Direction Alert Alarm Warning Module Calibration
Calibration Criteria
The vehicle departure alert alarm warning (VDAAW) system will require a recalibration procedure after replacing a module.
Calibration Procedure
Conditions to complete the self-calibration procedure:
*
Operating the vehicle at 56 km/h (35 mph) or more
*
Clear stretch of straight road
*
Driving during the daytime
*
Visible references (well defined lane markings, curbs, guard rails, fences, buildings, etc.)
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, fog, or driving at night or 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
When the VDAAW system is in calibration mode, the amber light in the IPC will remain illuminated. When the calibration is complete, the amber
indicator will turn green, indicating the system is ready to assist.
If the VDAAW system is disabled with the VDAAW switch, the amber light will turn off. The system will still run the calibration procedure in the
background.
Immediately after the self calibration procedure, there may be a delay in lane crossing alerts. The VDAAW system will run further calibration tests as the
vehicle is driven in order to improve performance.
Indication to Driver
Service Lane Departure Warning DIC message will display when DTC 0988 is set.
