GM Safety and ADAS Flashcards

Which GM system uses seat-mounted sensors to detect occupant weight and disable the passenger airbag for small occupants?

GM uses the Passenger Sensing System (PSS), also referred to as the Occupant Classification Module (OCM), which are functionally the same system in GM nomenclature.

After a GM vehicle is involved in an airbag deployment, which components must always be replaced regardless of visible damage?

What is the function of GM's Lane Keep Assist (LKA) system?

Answer: Alerts the driver with a vibration when drifting and can apply corrective steering torque

Lane Keep Assist provides a steering wheel vibration alert when unintentional lane departure is detected and can apply gentle corrective steering torque to guide the vehicle back.

GM's Automatic High Beam (IntelliBeam) system switches between high and low beams based on which input?

Answer: Forward camera detection of oncoming and leading vehicle lights

IntelliBeam uses a forward-facing camera to detect the headlights of oncoming vehicles and taillights of leading vehicles, automatically switching to low beams to avoid glare.

When a GM SRS diagnostic trouble code is set, what tool is required to read and clear the fault?

Answer: GM's Global Diagnostic System (GDS2) or equivalent bi-directional scan tool

SRS DTCs require a bi-directional scan tool such as GM's GDS2 to read, interpret, and clear faults, as generic OBD-II readers do not access body/SRS modules.

Which GM feature provides audible and visual warnings when the vehicle approaches preset speed thresholds in Teen Driver mode?
