CAFM Vehicle Maintenance and Repair 2

Question 1

A fleet vehicle's brake pedal feels spongy and sinks to the floor under moderate pressure. What is the most likely cause?

Accepted Answer

Air in the brake hydraulic system

Answer

Air in the hydraulic brake lines compresses under pressure, causing a spongy pedal feel and reduced braking effectiveness.

Question 2

When implementing a preventive maintenance schedule for a mixed fleet, which interval system is generally preferred over fixed mileage intervals?

Accepted Answer

Severity-adjusted intervals

Answer

Severity-adjusted intervals account for actual operating conditions (stop-and-go, idling, towing) which affect component wear more accurately than fixed mileage alone.

Question 3

A fleet manager notices repeated alternator failures on a specific vehicle model. What is the BEST first step in diagnosing this systemic issue?

Accepted Answer

Review repair history and identify common failure modes

Answer

Reviewing repair history to identify common failure modes helps pinpoint root causes such as accessory loads, wiring issues, or a faulty OEM part batch.

Question 4

What does the acronym 'OBD-II' refer to in fleet vehicle diagnostics?

Accepted Answer

On-Board Diagnostics, second generation

Answer

OBD-II is the standardized on-board diagnostics system mandatory on US vehicles since 1996, providing fault codes and sensor data via a standard port.

Question 5

A fleet vehicle is due for a timing belt replacement per manufacturer schedule. The technician finds the belt in apparently good condition. What should the fleet manager authorize?

Accepted Answer

Replace it on schedule regardless of appearance

Answer

Timing belt failures are catastrophic and often occur without visible warning signs; replacement on schedule is standard fleet risk management practice.
