Fleet Maintenance & Repair Flashcards

Which maintenance strategy involves replacing components based on condition monitoring data rather than fixed intervals?

Answer: Predictive maintenance

Predictive maintenance uses real-time condition data (vibration, oil analysis, telematics) to schedule repairs only when needed.

A fleet manager notices that a specific vehicle model consistently requires brake pad replacement at 25,000 miles. This information is best used to:

Answer: Establish a model-specific PM interval for brakes

Historical repair data by make/model should be used to set tailored preventive maintenance intervals.

What does OBD-II stand for in fleet vehicle diagnostics?

Answer: On-Board Diagnostics, second generation

OBD-II is the standardized on-board diagnostics system required on all US vehicles since 1996 that provides fault codes and sensor data.

When evaluating a third-party repair vendor for fleet use, which criterion is MOST critical for cost control?

Answer: Labor rate and parts markup transparency

Transparent labor rates and parts markup policies directly determine repair costs and enable accurate vendor benchmarking.

A 'first-time fix rate' KPI in fleet maintenance measures:

Answer: How often a repair resolves the issue without a repeat visit for the same problem

First-time fix rate tracks whether repairs are done correctly the first time, reflecting technician skill and diagnostic accuracy.

Which fluid analysis test is most commonly used to detect internal engine wear in fleet vehicles?

Answer: Spectrometric oil analysis (SOAP)

Spectrometric oil analysis detects metal particles from worn engine components, enabling early identification of internal damage.

What is the primary purpose of a warranty recovery program in a fleet maintenance operation?

Answer: To recoup repair costs from manufacturers for defective parts or workmanship

Warranty recovery programs systematically identify and file claims for repairs covered under manufacturer or extended warranties to reduce fleet costs.

Which type of maintenance contract shifts the risk of high repair costs to the vendor in exchange for a fixed monthly fee?

Answer: Full-service lease with maintenance

A full-service lease includes maintenance in a fixed monthly payment, transferring repair cost risk to the lessor.

Tire pressure monitoring systems (TPMS) in fleet vehicles primarily help reduce which operational cost?

Answer: Fuel consumption and tire wear

Proper tire inflation reduces rolling resistance (improving fuel economy) and prevents uneven wear that shortens tire life.

When setting up a parts inventory for a fleet shop, the 'economic order quantity' (EOQ) model helps determine:

Answer: The optimal order size that minimizes total inventory holding and ordering costs

EOQ balances the cost of placing orders against the cost of holding excess inventory to find the most cost-efficient reorder quantity.

A driver reports a grinding noise only during left turns. A technician should suspect which component first?

Answer: CV joint or wheel bearing on the front axle

Grinding during turns is a classic symptom of a worn CV joint or a failing wheel bearing, both of which are stressed during cornering.

What is the role of a national account program (NAP) with a major repair chain in fleet management?

Answer: It offers negotiated labor rates and parts pricing at multiple locations nationwide

National account programs leverage fleet purchasing volume to secure pre-negotiated rates and consistent service standards across a repair network.

According to best practices, how should a fleet manager handle a recall notice from a vehicle manufacturer?

Answer: Identify all affected VINs, prioritize safety-critical recalls, and schedule repairs promptly

Fleet managers must track affected VINs, assess safety urgency, and schedule recall repairs to avoid liability and ensure roadworthiness.

Which oil specification designation indicates that a motor oil meets the latest API service requirements for gasoline engines?

Answer: API SP

API SP is the current (as of 2020) top-tier specification for gasoline engines; CF and CK-4 are diesel ratings, and GL-5 is for gear oil.

A fleet manager wants to extend vehicle lifecycles to reduce capital costs. Which maintenance practice MOST directly supports this goal?

Answer: Strict adherence to manufacturer-recommended fluid change intervals and thorough inspections

Consistent, timely maintenance prevents cumulative wear damage that accelerates component failure and shortens useful vehicle life.

In a fleet maintenance context, 'deferred maintenance' refers to:

Answer: Maintenance scheduled beyond its due date to manage short-term budget constraints

Deferred maintenance is the intentional postponement of needed repairs or services, which accumulates risk and typically increases long-term costs.

A coolant system pressure test on a fleet vehicle is used to identify:

Answer: Leaks in the cooling system including the head gasket, hoses, and radiator

A pressure test pressurizes the cooling system to reveal leaks that may not be visible during a visual inspection.

Which telematics data point is MOST useful for identifying vehicles that need unscheduled brake inspections?

Answer: Hard braking event frequency

High hard-braking frequency accelerates brake wear and indicates vehicles that should be inspected ahead of their scheduled PM interval.

When a fleet vehicle's DTC (diagnostic trouble code) is cleared without repairing the underlying fault, what typically happens?

Answer: The MIL (malfunction indicator light) will illuminate again once the fault conditions recur

Clearing a code without fixing the problem only resets the ECM temporarily; the code returns when the fault conditions are detected again.

A fleet manager is evaluating tire vendors and receives a quote offering a lower per-tire price but a shorter treadwear warranty. The BEST analytical approach is to calculate:

Answer: Cost per mile or cost per tread depth unit over the expected life

Cost per mile (or per 32nd of tread) normalizes tire costs across different life expectancies, revealing true value regardless of purchase price.
