✍️ Sample ADT Questions & Answers
1. Which tool is best suited for capturing and displaying live CAN bus waveforms to verify signal integrity and data frame timing on an Audi?
An oscilloscope or dedicated CAN analyzer (such as a PCAN-USB) allows the technician to visualize differential CAN waveforms, verify bit timing, and decode live data frames.
2. Which suspension component helps absorb shocks from road irregularities?
The shock absorber, often working in conjunction with a spring, is a key component of the suspension system designed to dampen oscillations and absorb kinetic energy from road irregularities. It controls the spring's movement, preventing excessive bouncing and ensuring the tires maintain consistent contact with the road. This provides a smoother ride and improved handling.
3. What is the first step in ADT risk assessment?
Risk assessment begins with systematic identification of all potential hazards, forming the foundation for all subsequent analysis.
4. On an Audi with power-folding mirrors, a fault that causes only one mirror to fail to fold is MOST likely caused by:
A single-side failure typically indicates a localized fault at the mirror motor or its connector rather than a control module issue.
5. What is peer review in ADT Engine Performance & Tuning?
Peer review provides objective assessment by qualified professionals to identify improvements and ensure accountability.
6. On Audi FSI/TFSI engines, the high-pressure fuel pump is driven by:
The high-pressure fuel pump on FSI/TFSI engines is mechanically actuated by a dedicated lobe on the intake or exhaust camshaft.
