GM Dynamic Calibration Processes

IMPORTANT:    Always be careful of traffic conditions and safety around the vehicle

                        Your test vehicle may not be equipped with all safety systems 

Front Camera – Windshield

• GM Service Programing System (SPS) programming is required after replacement
• Some vehicles will immediately begin calibration after programming, vehicle other may require calibration to be started using GDS2.
  • Refer to Service Information for specific programming and calibration instructions after replacement
• Ensure windshield glass has been properly installed, is clean, NOT damaged or cracked and camera is not damaged, dirty or obstructed
• Make sure the vehicle is being driven in an area conducive to calibration. An ideal calibration environment is a two-lane divide highway with lane makings on both side of the lane, driving the vehicle between 56-90km/h (35-56 MPH).
• Avoid the following:
  • Heavy traffic
  • Stop and go traffic
  • Mountain roads
  • Curves in the roadway
  • Adverse weather, such as snow, fog, or extreme rain, or driving directly into the sun

Long Range Radar Sensor Module

• GM Service Programing System (SPS) programming is required after replacement
• Prior to driving the vehicle make sure the surface in front of the radar sensor is clean.
• Verify the mounting area is not damaged and allows the module to face the intended direction. 
• Make sure the vehicle is being driven in an area conducive to calibration.
  • An ideal calibration environment has stationary objects on the roadside, such as mailboxes and street signs, minimal curves and hills, multiple vehicles to follow at a distance of 30-50 m (100-165 ft) while driving the vehicle greater than 56 km/h (35 MPH).
• Drive the vehicle within the following conditions for 10–30 minutes or until calibration is complete. The “Service Driver Assist” message will turn off when calibration is complete.
  • Drive at speeds between 35 – 56 mph (56-90 km/h) 
  • Minimize tight curves
  • Avoid extreme acceleration or deceleration
  • Follow one or multiple vehicles. (typical vehicle traffic is sufficient, but vehicles 30m – 50m (100 –165ft) away are most effective at decreasing the calibration time)
  • Drive in an environment that has stationary objects on the side of the road (street signs, guard rails, mail-boxes, fences, etc)
• Verify proper calibration by observing that the “Service Driver Assist” message turns off within 10–30 minutes of normal driving.
• Avoid the following:
  • Heavy traffic
  • Stop and go traffic
  • No traffic
  • Mountain or hilly roads
  • Sharp curves in the roadway
  • Tunnels

Left and Right-Side Object Sensor Modules

• Since the Left and Right-Side Object Sensor Modules continuously perform coarse and fine calibration during operation. no calibration is required as a part of service.
• Ensure you follow the following directions prior to and during a dynamic calibration test drive
  • DO NOT operate vehicle in an area where there no traffic or a limited number of road-side objects
  • Ensure there is no dirt, mud or other build-up in the sensor area
  • Ensure there are no bumper stickers or labels on the rear fascia or bumper near the sensor
  • Ensure there is no damage to the rear fascia
