Vehicle Preparation For Module Alignment
WARNING: This page is about a different car, the 2021 Chrysler 300. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
The ACC module lens could be obstructed by snow/ice, dirt, mud, and other environmental debris. A message will appear on dash to clean the lens when needed. The module lens is equipped with a heating element that can melt snow/ice. Otherwise the lens must be cleaned manually. Also note that the assembly could be misaligned or damaged from impact or water intrusion.
- Repair or replace any ineffective, worn or damaged body components. Repair any loose or cracked fascia components that might interfere with the sensor field of view. The lens dome of the module should be roughly centered in the opening of the fascia.
- Verify proper tire inflation pressures.
- Remove any accumulations of mud, snow or ice from the vehicle underbody.
- Verify that there is no load in the vehicle (cargo or passengers), except for the driver.NOTE:
The vehicle MUST be placed upon a wheel alignment or frame rack to achieve the proper module vertical alignment results. If a wheel alignment or frame rack is not available, then a verified level surface can be used. When using the wheel alignment rack, the fore - after specifications must be within 0 (+/- 0.2) degrees.
- Rock the vehicle side-to-side three times to allow the suspension to stabilize.
- Bounce the front and rear suspension three times by pushing downward on the front and rear bumpers and releasing.
- Verify correct vehicle suspension height.
