TDS2254E - CMT Driving Stability Exam

What does the Electronic Stability Program (ESP) primarily help prevent in vehicles?

• Overheating of the engine

• Loss of traction and skidding

• Fuel consumption

• Wear of brake pads

What is the primary function of the Integrated Braking Control (IBC) system?

• Controls vehicle speed during uphill driving

• Manages engine output for optimal performance

• Ensures smooth operation of the brakes by coordinating with the ABS

• Enhances engine fuel efficiency

In a vehicle with an Electronic Parking Brake (EPB) system, what is the benefit over traditional parking brakes?

• It allows the vehicle to park on steeper inclines

• It provides automatic braking when the vehicle is in motion

• It requires less driver effort to engage and disengage

• It reduces tire wear

What is the role of the yaw rate sensor in the ESP system?

• It detects wheel speed

• It measures the vehicle’s rotation around its vertical axis

• It monitors brake pad wear

• It controls engine torque output

How does ESP improve driving stability during emergency maneuvers?

• By applying brake pressure to individual wheels to prevent skidding

• By increasing the engine power output

• By adjusting the ride height of the vehicle

• By automatically adjusting the steering angle

What is the function of the anti-lock braking system (ABS) in conjunction with ESP?

• It prevents the engine from stalling.

• It helps prevent wheel lock-up during emergency braking.

• It reduces brake pad wear.

• It improves fuel efficiency.

How can the IBC system improve braking performance?

• By reducing the brake temperature during heavy braking

• By preventing the wheels from locking up during heavy braking

• By increasing the size of the brake rotors

• By distributing braking force equally to all wheels

What is the main advantage of an Electronic Parking Brake (EPB) over a traditional manual parking brake?

• It increases engine power

• It makes parking more efficient and easier

• It reduces brake wear

• It reduces fuel consumption

How does ESP assist in handling a vehicle during an understeer situation?

• It reduces engine power and applies brakes to the outside front wheel

• It increases the engine speed to correct the trajectory

• It adjusts the steering angle

• It disengages the ABS system

When diagnosing an issue with the ESP system, which sensor is typically checked first?

• Wheel speed sensors

• Oxygen sensor

• Fuel pressure sensor

• Crankshaft position sensor
