CAADE CAADE Vehicle Safety Systems and Technology Questions and Answers 2 — Questions and Answers
Question 1: What is the purpose of a static ADAS calibration versus a dynamic ADAS calibration?
- Static uses a scan tool; dynamic uses a test drive only
- Static is performed in a controlled indoor environment with targets; dynamic is performed while driving at specified speeds (Correct answer)
- Static applies to cameras only; dynamic applies to radar only
- Static is done post-paint; dynamic is done pre-paint
Correct answer: Static is performed in a controlled indoor environment with targets; dynamic is performed while driving at specified speeds
Static ADAS calibration uses precise indoor targets and fixtures, while dynamic calibration is performed by driving the vehicle under specific conditions to reset sensor alignment.
Question 2: A vehicle has lane-keeping assist (LKA). After a front-end collision repair, what step must be documented in the repair estimate?
- Replacement of the steering rack
- ADAS recalibration and verification scan (Correct answer)
- Replacement of all four tires
- Fuel system inspection
Correct answer: ADAS recalibration and verification scan
Lane-keeping assist relies on a calibrated forward camera, so after front-end repairs the system must be recalibrated and a verification scan documented.
Question 3: Which of the following correctly describes the role of a crash data recorder (CDR/EDR) in a damage appraisal?
- It determines paint color codes
- It stores pre-crash speed, braking, and seatbelt status data useful for liability and severity assessment (Correct answer)
- It controls airbag inflation timing in real time
- It logs fuel consumption data only
Correct answer: It stores pre-crash speed, braking, and seatbelt status data useful for liability and severity assessment
The crash data recorder (Event Data Recorder/EDR) captures pre-crash data such as speed, throttle, and braking that can inform damage severity and liability analysis.
Question 4: After replacing a front bumper on a vehicle with an automatic emergency braking (AEB) system, what must the appraiser note as a required repair step?
- Replace brake pads and rotors
- Recalibrate the front radar sensor to manufacturer specifications (Correct answer)
- Flush brake fluid
- Replace the ABS module
Correct answer: Recalibrate the front radar sensor to manufacturer specifications
AEB systems rely on a front radar sensor that must be recalibrated to factory specifications after bumper replacement to maintain accurate collision detection.
Question 5: What is the significance of a 'supplemental restraint system' (SRS) warning light remaining on after collision repairs?
- It indicates a minor electrical glitch that clears itself
- It indicates an unresolved fault in the airbag or seat belt system that could prevent deployment in a future crash (Correct answer)
- It means the battery needs replacement
- It signals the need for an oil change
Correct answer: It indicates an unresolved fault in the airbag or seat belt system that could prevent deployment in a future crash
An illuminated SRS warning light means the restraint system has an unresolved fault and may not deploy correctly in a subsequent collision, making it a critical safety concern.
Question 6: Which tool is used to retrieve and document airbag control module fault codes during a collision damage appraisal?
- Infrared thermometer
- Diagnostic scan tool (OBD-II scanner with SRS capability) (Correct answer)
- Paint thickness gauge
- Ultrasonic measuring system
Correct answer: Diagnostic scan tool (OBD-II scanner with SRS capability)
A diagnostic scan tool with SRS capability connects to the OBD-II port to retrieve fault codes from the airbag control module during post-collision appraisal.
