1) SPTAC Calibration (Service Point Target Auto Calibration)

What it does

• Automatically calibrates the camera service point for Lane Departure Warning System (LDWS)
• Ensures correct detection of lane markers under standard conditions

When it is required

• After windshield replacement

2) TAC Calibration (Target Auto Calibration)

What it does

• Auto calibrates target lane positions
• Adjusts LDWS detection for vehicle-specific alignment and lane width

When it is required

• After alignment changes
• After suspension or chassis modifications affecting camera angle
• When LDWS warnings or misdetections occur

Conditions that must be met

• Clear lane markings
• Vehicle stationary or driving at low speed as instructed
• Camera and sensors properly connected

3) SPC Calibration (Calibration Including Environment Conditions)

What it does

• Performs full calibration accounting for environmental conditions:
• Lighting
• Road surface
• Weather
• Ensures reliable LDWS function under various real-world conditions

When it is required

• After camera or system replacement
• After major environmental or alignment changes
• When system reliability is impaired

Conditions that must be met
