Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Vehicle Direction Alert Alarm Warning Module Calibration
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, confirm the lane departure warning system is on/enabled. The amber light on the instrument panel cluster (IPC) should illuminate to indicate the process has been initiated. Disconnect the scan tool then operate the vehicle in the following conditions until the amber indicator turns off:
- 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 and well defined lane markings.
When the lane departure warning system is in calibration mode, the amber light on the 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
