Glass, Trim, and Interior Component Service
What this domain tests
This domain tests glass, trim, and interior component service, including windshield replacement, clips and moldings, airbag and seatbelt components, and ADAS camera awareness. The exam checks materials, safe drive-away time, and calibration.
Core rules
- Windshield urethane, primer, and applicator must meet OEM specifications; follow safe drive-away time and VIN requirements.
- Prepare glass and pinchweld per product directions; do not touch primed surfaces; replace damaged moldings and clips.
- Interior trim removal requires trim tools and care around airbags, pretensioners, and wiring; disconnect the battery as specified.
- A camera behind the windshield often requires static or dynamic calibration after replacement; scan for DTCs.
- Check operation of windows, locks, mirrors, seats, and airbags after assembly.
Worked example
A windshield with a forward camera is replaced. The technician pre-scans, removes the glass, primes the pinchweld, applies the specified urethane bead, sets the glass, observes drive-away time, and calibrates the camera. Reasoning: the camera aims through the glass; a poor bead or skipped calibration can affect lane-keeping and collision warnings.
Traps
Using wrong urethane or no primer; driving before safe drive-away time; reusing damaged clips; not calibrating the camera; damaging airbag wiring; skipping the post-scan.
