VW Safety Systems & Standards 2 — Questions and Answers
Question 1: Which VW safety system uses radar and camera fusion to detect pedestrians and automatically apply brakes?
- Front Assist with Pedestrian Monitoring (Correct answer)
- Park Assist Pro
- Lane Assist Plus
- Traffic Jam Assist
Correct answer: Front Assist with Pedestrian Monitoring
Front Assist with Pedestrian Monitoring combines radar and camera data to detect pedestrians and trigger autonomous emergency braking.
Question 2: What is the correct procedure when diagnosing an airbag system with a stored fault code on a VW vehicle?
- Clear the code and test-drive immediately
- Disconnect battery, wait 10 minutes, then diagnose with ODIS (Correct answer)
- Replace the airbag control module first
- Use a generic OBD-II scanner to read live data
Correct answer: Disconnect battery, wait 10 minutes, then diagnose with ODIS
Disconnecting the battery and waiting 10 minutes allows capacitors to discharge before using VW's ODIS diagnostic system safely.
Question 3: In VW's Electronic Stability Control (ESC), what does the system do when it detects understeer?
- Applies braking to the rear outer wheel
- Applies braking to the front inner wheel (Correct answer)
- Increases throttle to all wheels equally
- Applies braking to the front outer wheel
Correct answer: Applies braking to the front inner wheel
During understeer, ESC brakes the front inner wheel to redirect the vehicle back toward the intended steering path.
Question 4: What VW standard governs the minimum tensile strength requirement for seatbelt webbing?
- FMVSS 208
- FMVSS 209 (Correct answer)
- ECE R16
- ISO 6683
Correct answer: FMVSS 209
FMVSS 209 specifies the performance requirements for seatbelt assemblies including webbing tensile strength in the US market.
Question 5: A VW technician notes the Tire Pressure Monitoring System (TPMS) warning lamp flashes for 60 seconds then stays on. What does this indicate?
- A tire is significantly underinflated
- The TPMS sensor battery is low
- The system has a malfunction (Correct answer)
- Tires need rotation
Correct answer: The system has a malfunction
A TPMS warning lamp that flashes for about 60–90 seconds then remains illuminated signals a system malfunction, not just low pressure.
Question 6: Which component in VW's pyrotechnic pretensioner system actually retracts the seatbelt during a collision?
- Shape memory alloy wire
- Compressed gas piston
- Electrically ignited propellant charge (Correct answer)
- Electromagnetic solenoid
Correct answer: Electrically ignited propellant charge
Pyrotechnic pretensioners use an electrically ignited propellant charge to rapidly retract seatbelt slack during a crash event.
Question 7: When replacing a side curtain airbag on a VW vehicle, what is the MOST important step before beginning removal?
- Recalibrate the yaw sensor
- Confirm no fault codes are active
- Disable the SRS system and allow capacitor discharge time (Correct answer)
- Update the airbag module software
Correct answer: Disable the SRS system and allow capacitor discharge time
Disabling the SRS (Supplemental Restraint System) and allowing sufficient capacitor discharge time prevents accidental airbag deployment.
