Q21When replacing a windshield with rain sensors, which step is MOST critical to ensure proper system operation?
✓ Correct answer: D. Ensuring correct alignment of the sensor according to manufacturer specifications
Proper alignment of rain sensors during installation is critical for the system to function correctly. The sensor must be positioned precisely according to manufacturer specifications to detect moisture on the glass surface.
Q22Which condition would most likely prevent proper adhesion when installing stationary glass?
✓ Correct answer: C. Contamination of the pinch weld surface
Contaminants on the pinch weld surface (such as oils, old adhesive, or debris) will prevent proper bonding of new urethane adhesive, leading to potential leaks or glass failure.
Q23Technician A says that heated backglass requires special handling during removal to prevent damage to the heating elements. Technician B says that the heating elements in the glass can be repaired if damaged during removal. Who is correct?
✓ Correct answer: B. Technician A only
Heated backglass requires special care during removal to prevent damaging the heating elements, which cannot be repaired if broken. Once heating elements are damaged, the entire glass assembly must be replaced.
Q24When preparing a pinch weld for stationary glass installation, what is the proper procedure for treating exposed bare metal areas?
✓ Correct answer: A. Apply corrosion protection primer according to manufacturer specifications
Exposed bare metal on pinch welds must be treated with proper corrosion protection (primer) to prevent rust formation that could compromise the glass bond and vehicle structural integrity.
Q25What is the primary purpose of the 'safe drive-away time' specified by adhesive manufacturers?
✓ Correct answer: D. To ensure the adhesive has cured enough to maintain structural integrity during a collision
The safe drive-away time ensures the adhesive has cured sufficiently to provide proper structural integrity and restraint system support, preventing glass displacement in the event of a collision.
Q26When installing a windshield with an integrated antenna, what must a technician verify before completing the installation?
✓ Correct answer: C. Proper electrical connections for the antenna system
Before completing installation of a windshield with an integrated antenna, the technician must verify proper electrical connections to ensure radio reception functions correctly.
Q27What tool is MOST appropriate for removing urethane adhesive from a pinch weld when preparing for new glass installation?
✓ Correct answer: B. Urethane cutting tool
A urethane cutting tool (cold knife or power tool with specific cutting blade) is designed to effectively remove old urethane without damaging the pinch weld surface, providing a proper base for new adhesive application.
Q28After replacing a windshield with embedded ADAS (Advanced Driver Assistance System) components, what is required before returning the vehicle to the customer?
✓ Correct answer: A. Calibration of the ADAS system according to manufacturer procedures
ADAS systems (like forward collision warning, automatic emergency braking) that use cameras or sensors mounted to the windshield require calibration after glass replacement to ensure they function correctly and safely.
Q29When stationary glass is being replaced, what is the MOST important consideration regarding supplemental restraint systems?
✓ Correct answer: D. Proper glass installation is critical for airbag deployment
The windshield is a structural component that supports proper deployment of airbags, particularly passenger-side airbags. Proper installation and adhesive curing is critical for the SRS to function correctly in a collision.
Q30Which of these conditions would require a technician to replace rather than reuse the existing molding when installing a new windshield?
✓ Correct answer: C. The vehicle manufacturer specifies one-time-use moldings
Many modern vehicles use one-time-use moldings that are designed to work with specific adhesion properties and dimensions. Once removed, these moldings lose their shape and adhesive properties and must be replaced according to manufacturer specifications.
