ASE C1 Shop Operations — Questions and Answers
Question 1: 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?
- Once the vehicle goes to the glass company, the customer has to deal with them directly about any problems
- The sublet work should stay off the repair order to avoid marking up another company's labor
- The shop stays responsible to the customer for the sublet work, and it should appear on the repair order (Correct answer)
- Sublet work can be sent out without the customer's authorization if it is cheaper than doing it in-house
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.
Sublet work is any repair the shop sends to an outside vendor, such as glass, machine work, alignments or upholstery. The customer authorized your shop, so your shop keeps responsibility for the quality, cost and timing of that work. The sublet should be written on the repair order with its charges, and the customer must authorize it like any other repair. The service consultant tracks the sublet vendor's progress so the promised completion time still holds.
Question 2: A customer returns two days after a repair and says the original concern is still there. What should the service consultant do first?
- Review the original repair order and have the concern verified, ideally with the customer present or on a road test (Correct answer)
- Write a new repair order for diagnosis and quote the customer the standard diagnostic fee
- Tell the customer the problem is probably unrelated to the original repair
- Send the vehicle to a different technician without telling the first technician
Correct answer: Review the original repair order and have the concern verified, ideally with the customer present or on a road test
Handling a comeback starts with checking what was done before and confirming that the concern is actually still there.
A comeback is a vehicle that returns because the earlier repair did not fix the concern or caused a new one. The consultant should pull the original repair order to see the diagnosis and work performed. The concern should then be verified, for example on a road test with the customer, so everyone agrees on the symptom. Treating comebacks quickly and without blame protects customer trust. Tracking them by cause and by technician also helps the shop find training or process problems.
Question 3: A customer drops off a vehicle after hours. The key-drop envelope says only "brakes making noise" and gives a phone number. What is the best first action the next morning?
- Dispatch the vehicle for a complete brake job so it is ready by noon
- Wait for the customer to call the shop before doing anything
- Have a technician replace the front pads, since that is the most common cause of brake noise
- Call the customer to clarify the concern and get authorization before work begins (Correct answer)
Correct answer: Call the customer to clarify the concern and get authorization before work begins
After-hours drop-offs usually come with incomplete information and no signed authorization, so the consultant has to contact the customer before work is dispatched.
An after-hours drop-off skips the usual write-up conversation, so the consultant does not know the symptom details or what the customer has approved. Calling the customer lets the consultant ask when and where the noise happens, confirm contact preferences and give an estimated completion time. The shop needs authorization at least for diagnosis before any work starts. Good drop-off envelopes ask for this information up front, but a follow-up call is still the standard practice.
Question 4: While the car is in the shop, the consultant learns that a needed part is backordered and won't arrive for three days. What is the most appropriate action?
- Say nothing until the part arrives so the customer doesn't worry
- Promptly contact the customer, explain the delay, give a revised completion time and discuss options such as alternate transportation (Correct answer)
- Install a used part from another vehicle in the shop without telling the customer
- Cancel the repair order and ask the customer to come pick up the vehicle
Correct answer: Promptly contact the customer, explain the delay, give a revised completion time and discuss options such as alternate transportation
Parts delays should be shared right away, along with a new completion time and options for the customer.
Parts availability affects completion times directly, so consultants should check parts status as soon as a repair is approved. If a part is backordered, the customer should hear about it right away with a realistic new completion time. Options may include a rental or loaner, reassembling the vehicle so it can be driven if that is safe, or another approved source for the part. Any change in part type, such as aftermarket or used instead of OEM, needs the customer's approval.
Question 5: To schedule appointments so the shop is neither overbooked nor underused, the consultant should base the daily schedule mainly on:
- The number of vehicles that fit in the parking lot
- Booking the same number of cars each hour, whatever the job
- Available technician hours compared with the estimated labor time of the booked jobs (Correct answer)
- Taking every appointment request that comes in that day
Correct answer: Available technician hours compared with the estimated labor time of the booked jobs
Shop capacity is set by productive technician hours, so appointments should be matched to the labor time available.
A shop's real capacity is the number of productive hours its technicians have, not the number of cars it can park. Consultants estimate the labor time for each appointment and load the schedule until those hours are used, leaving some room for diagnostic surprises, added work and comebacks. Spreading jobs by type and skill level keeps every technician busy. This approach cuts down on missed promise times and on idle technicians.
Question 6: During a scheduled maintenance service, a technician finds a leaking water pump. What should happen before the technician replaces it?
- The technician should replace it right away, since the customer will want it fixed
- The consultant should contact the customer, explain the finding and get authorization along with a revised estimate and completion time (Correct answer)
- The consultant should add it to the final bill and explain it when the customer picks up the car
- The technician should note it on the RO and wait until the next scheduled service
Correct answer: The consultant should contact the customer, explain the finding and get authorization along with a revised estimate and completion time
Additional work requires the customer's authorization, and the customer should also hear the updated cost and timing.
Technicians often find more needed repairs while working on a vehicle. The consultant presents the finding to the customer, explains why it matters and gives a price and a revised completion time. Work goes ahead only after authorization, and the approval should be recorded on the repair order with the date, time and name of the person who approved it. Doing unapproved work can break consumer protection rules and damage the customer's trust.
Question 7: A consultant sees at 2:00 p.m. that a vehicle promised for 4:00 p.m. won't be finished until tomorrow. What is the best course of action?
- Wait until the customer arrives at 4:00 p.m. and explain the delay then
- Have the technician rush the job to try to meet the original time
- Leave the customer a message after the shop closes
- Call the customer right away, explain the reason and give a realistic new completion time (Correct answer)
Correct answer: Call the customer right away, explain the reason and give a realistic new completion time
Customers should hear about a missed promise time as soon as the consultant knows, not when they show up.
Monitoring repair progress during the day lets the consultant spot delays early. When a promise time can't be met, calling the customer right away gives them time to arrange other transportation or change their plans. The consultant should explain the reason in plain terms and give a realistic new time. Rushing a technician to meet a deadline can lead to mistakes and comebacks, so setting a new expectation honestly is the better choice.
Question 8: Which job should normally go to the shop's most experienced diagnostic technician?
- An intermittent no-start with no stored diagnostic trouble codes (Correct answer)
- An oil and filter change with a tire rotation
- A wiper blade replacement
- A cabin air filter replacement
Correct 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.
Good dispatching matches each job to the right skill level. Routine maintenance goes to entry-level or lube technicians, and difficult diagnostic work goes to the most experienced technicians. An intermittent concern with no codes calls for advanced testing skills and judgment. Dispatching this way improves fix-it-right-the-first-time rates, reduces comebacks and keeps senior technicians on work that uses their training.
Question 9: Which repair order concern statement gives the technician the most useful information?
- Check brakes
- 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 (Correct answer)
- Brakes bad — replace pads
- Customer complains about noise
Correct 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.
The repair order is the main way the consultant communicates with the technician. A useful concern statement describes the symptom in the customer's terms and includes the conditions: when it happens, where on the vehicle, how often and when it started. Consultants should not write a diagnosis like "replace pads," because that can send the technician in the wrong direction or authorize the wrong work. Clear write-ups cut diagnostic time and help prevent comebacks.
Question 10: A customer wants to wait at the dealership while the work is done. Which service is best suited to a waiter appointment?
- Diagnosing an intermittent transmission shifting concern
- Replacing a cylinder head gasket
- An oil change and a multipoint inspection (Correct answer)
- Tracing an electrical drain that happens overnight
Correct 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.
Waiter appointments work best for short, routine jobs with predictable labor times, such as oil changes, inspections and simple maintenance. Diagnostic concerns, especially intermittent ones, and major repairs have uncertain completion times and often need parts or extended testing. Many shops schedule waiters at set times and keep technician capacity available for them. Booking the right jobs as waiters keeps promise times realistic and customers satisfied.
