Sample B5 questions

Straight from the bank — answers highlighted, with the explanation underneath.

Camber angle is best defined as:

  1. The forward or rearward tilt of the steering axis viewed from the side
  2. The inward or outward tilt of the wheel at the top when viewed from the front
  3. The difference in distance between the front and rear of a pair of tires
  4. The inward tilt of the steering axis viewed from the front
WhyCamber is the tilt of the wheel/tire centerline from true vertical viewed from the front; outward at the top is positive. It is a primary pull and tire-wear angle checked after a collision.

Technician A says that after airbag deployment the airbag module, inflator, and pyrotechnic seat-belt pretensioners must all be replaced. Technician B says the crash/impact sensors and, per many OEMs, the SRS control module are one-time-use items replaced after deployment.

  1. Technician A only
  2. Technician B only
  3. Both Technicians A and B
  4. Neither Technician
WhyDeployment consumes the pyrotechnic devices and subjects sensors and the module to peak forces; OEM procedures specify replacing the deployed components and often the sensors and control module.

Before welding on a collision-damaged vehicle, all of the following are recommended EXCEPT:

  1. Disconnect the battery
  2. Attach the welder ground clamp close to the weld area
  3. Protect or remove nearby electronic modules and airbags
  4. Leave the battery connected to power a memory saver during welding
WhyWelding current with the battery connected can destroy modules and deploy airbags; disconnect the battery and clamp the ground near the weld. A memory saver would keep circuits—including SRS—live.
