Mixed Deck — All ASE C1 Topics Flashcards

A customer reads the VIN to a service consultant over the phone and says one of the characters is the letter "O." What should the consultant conclude?

Answer: The character is really a zero, because I, O and Q are not used in VINs

Standard 17-character VINs never use the letters I, O or Q because they are too easy to confuse with the numbers 1 and 0. The character must be the number zero.

A multipoint inspection finds a cabin air filter that is due, front brake pads at 2 mm, and a slightly seeping valve cover gasket. How should the service consultant present these findings?

Answer: Prioritize safety first: recommend the brake pads now, then explain the other items with suggested timing

Brake pads at 2 mm are at or near the minimum and are a safety concern, so they come first. The other items should still be documented and explained with the right urgency so the customer can make informed decisions.

During write-up, which piece of customer information is most important to confirm so the shop can reach the customer for authorization?

Answer: The customer's best phone number and preferred contact method during the day

The shop must be able to reach the customer quickly during the day to get approval for extra work, so the best contact number and preferred method are essential.

Why should a service consultant do a walk-around of the customer's vehicle with the customer present at write-up?

Answer: To note existing damage and spot possible service needs before the vehicle goes into the shop

A walk-around records existing dents, scratches and other conditions, which prevents later disputes, and it often turns up extra needs such as worn tires or burned-out bulbs.

Which repair order concern statement gives the technician the most useful information?

Answer: Customer says squeal from the front when braking lightly at low speed, mostly on the first stops of the morning; started about two weeks ago

A good concern statement records the symptom along with when, where and how often it happens, without assuming a repair.

On a hybrid or electric vehicle, what is the main job of the inverter?

Answer: To convert the battery's high-voltage DC into AC to drive the traction motor, and to convert AC back to DC during regeneration

The high-voltage battery stores DC, but most traction motors run on three-phase AC. The inverter converts DC to AC for driving and changes AC back to DC to recharge the battery during regenerative braking.

A customer says their car "makes a grinding noise." Which way of writing this concern on the repair order will help the technician most?

Answer: Customer states grinding noise from front of vehicle when braking at low speeds, mostly in the morning; started about one week ago

A good concern statement uses the customer's own description and adds where, when and under what conditions the symptom happens, so the technician can reproduce it.

A customer wants to wait at the dealership while the work is done. Which service is best suited to a waiter appointment?

Answer: An oil change and a multipoint inspection

Waiter appointments should be short, predictable jobs that can reliably be finished within the customer's visit.

A customer wants to know if their used vehicle has any open safety recalls. Which source lets the consultant check this by the vehicle's VIN?

Answer: The NHTSA recall lookup or the manufacturer's dealer recall system

NHTSA's VIN-based recall lookup and the manufacturer's dealer system both show whether a specific vehicle has unrepaired safety recalls.

A customer's vehicle needs a windshield replacement, and your shop sends that work to an outside glass company. Which statement about this sublet repair is correct?

Answer: The shop stays responsible to the customer for the sublet work, and it should appear on the repair order

The customer's agreement is with the shop that wrote the repair order, so the shop answers for sublet work and lists it on the RO.

A customer walks up to the service counter while the consultant is on the phone with another customer. What is the most professional response?

Answer: Make eye contact and acknowledge the customer with a gesture or quick word that they will be helped shortly

Acknowledging a waiting customer right away tells them they have been seen, while the current customer still gets proper service.

A customer's in-warranty vehicle has an engine failure. The customer had every oil change done at an independent shop and kept the receipts. What is the correct position on warranty coverage?

Answer: Coverage cannot be denied just because an independent shop did the maintenance

Federal law generally prohibits voiding a warranty just because maintenance or parts came from someone other than the dealer, unless that service or part caused the failure.

Which job should normally go to the shop's most experienced diagnostic technician?

Answer: An intermittent no-start with no stored diagnostic trouble codes

Complex, intermittent diagnostic work should go to the technician with the strongest diagnostic skills.

A technician changes the oil on a vehicle equipped with an oil life monitoring system but does not reset the system. What is the most likely result?

Answer: The system will keep counting down from the old value and show an early, inaccurate oil change reminder

Most oil life monitors calculate remaining life from operating conditions and do not sense fresh oil. If the system is not reset, it keeps calculating from the old oil's remaining life.

While explaining a recommended wheel alignment, which statement best turns a feature into a customer benefit?

Answer: "Correct alignment helps your tires wear evenly, so they last longer and the car tracks straight."

A benefit statement tells the customer what the service does for them, such as longer tire life and better handling. The other options only state features or technical facts.

A customer drives mostly 3-mile trips to work, often in sub-freezing weather, and asks which maintenance schedule applies. According to most manufacturers' guidelines, which schedule should the service consultant recommend?

Answer: The severe service schedule, because frequent short trips in cold weather are a listed severe condition

Manufacturers list frequent short trips, especially in extreme temperatures, as a severe operating condition. Under those conditions the engine rarely reaches full operating temperature, so moisture and fuel build up in the oil.

A customer complains that their vehicle was ready two hours later than promised. Which response best handles the complaint?

Answer: Apologize, briefly explain the cause without blaming others, and say what will be done to prevent it next time

Taking responsibility, giving an honest explanation and committing to improve keeps the customer's trust after a service failure.

After rotating the tires on a vehicle whose TPMS displays the pressure at each individual wheel position, what follow-up step may be required?

Answer: Perform a TPMS sensor relearn so the system knows each sensor's new location

Systems that report pressure by wheel position need to know which sensor is at which corner. After a rotation, many vehicles require a relearn procedure so the warnings show the correct wheel.

Many manufacturers specify replacing brake fluid at regular time intervals. What is the main reason?

Answer: Glycol-based brake fluid absorbs moisture over time, which lowers its boiling point and can cause internal corrosion

DOT 3, DOT 4, and DOT 5.1 brake fluids are hygroscopic, meaning they absorb moisture. Water in the fluid lowers its boiling point, which raises the risk of brake fade under heavy use, and it can corrode internal brake components.

A warranty claim needs the vehicle's month and year of manufacture. Where is this information most reliably found?

Answer: The safety certification label on the driver's door jamb or B-pillar

The FMVSS certification label, usually on the driver's door jamb or B-pillar, shows the month and year of manufacture. The VIN shows the model year, which can differ from the build date.
