✍️ Sample 310S Questions & Answers
1. What does a waveform with missing humps on an alternator AC ripple test indicate?
A normal three-phase alternator produces a smooth ripple pattern. Missing humps indicate that one or more rectifier diodes have failed, preventing that phase's output from contributing to the DC supply.
2. What is the purpose of the emergency brake assist (BA) system?
Brake assist monitors the speed and force of brake pedal application. If it detects a panic stop (fast pedal application), it immediately applies full braking force, reducing stopping distance for drivers who may not press hard enough.
3. When testing a Hall-effect sensor, what type of signal output should a technician expect?
Hall-effect sensors produce a clean digital square wave signal that switches between a reference voltage (high) and ground (low) as a trigger wheel or shutter blade passes through the sensor's magnetic field.
4. What causes a vibration felt throughout the vehicle during acceleration from a stop?
Worn U-joints develop play that causes the driveshaft to vibrate during acceleration. The vibration is typically felt at low speeds and during acceleration when the most torque is transmitted through the drivetrain.
5. What is the purpose of the proportioning valve in a brake system?
During braking, weight transfers to the front wheels, reducing rear wheel traction. The proportioning valve limits pressure to the rear brakes, preventing them from locking up before the front brakes.
6. A front-wheel-drive vehicle exhibits a humming noise that changes with vehicle speed but not engine RPM. The noise changes tone when swerving left or right. What is the most likely cause?
A speed-dependent humming that changes with lateral load (swerving) is characteristic of a worn wheel bearing. Swerving loads or unloads the bearing, changing the noise. The sound does not change with engine RPM since it is driven by wheel speed.
