Told You, You Should Have Bought an Autel.
Every vehicle that leaves your shop because you can’t complete the job represents more than one lost repair. It can mean lost diagnostic time, labor, and parts sales. It can also mean a lost customer.
Customers remember when a shop solves a difficult problem. They also remember hearing, “I’m sorry, we can’t find the problem,” or “We can’t perform that service.” And they tell family, friends and coworkers about both experiences.
One unfinished job can become more than one lost opportunity. For independent repair shops, today’s vehicles are becoming more complex, and diagnostic equipment has to keep pace.
Get Through the Gateway
Secure gateways are appearing on an increasing number of vehicles—from Mercedes-Benz, Volkswagen and Audi to Jeep, Chrysler, Ram and Nissan. These systems can restrict bidirectional controls, service functions, and other procedures unless the technician has authorized access.
Autel diagnostic tablets provide a path to authorized SGW access on supported vehicles, helping technicians get through the gateway and continue the job. And on some vehicles, the blocked function can be something as routine as clearing a trouble code or resetting an oil maintenance light. SGW access isn’t just about advanced diagnostics. It’s an increasing part of everyday service.
Find the Functions You Need
Getting into the vehicle is one thing. Having the right functions once you’re in is another. Modern vehicles can contain dozens of modules managing hundreds of software-controlled functions. Autel diagnostic platforms provide extensive special, hidden and vehicle-specific functions on supported vehicles, helping technicians access resets, relearns, adaptations and other procedures needed to complete repairs.
The important question isn’t how many functions appear on a specification sheet. It’s whether the tool has the function you need when the vehicle is in your bay.
When the Electrical Problem Gets Crazy
Every shop eventually gets one: warning lights everywhere, U-codes across multiple systems, modules offline and communication faults that don’t seem to make sense. This is where the Ultra S2 series tablets’ Topology and Network Ping can change the diagnostic approach
On supported vehicles, Topology 3.0 provides a visual representation of the vehicle network and module status, allowing technicians to see how systems relate to one another.
Network Ping takes the diagnosis further with active module and network analysis, enabling the technician to locate and directly ping ECUs to test signal quality and network integrity.
Topology 3.0 gives you the map. Ping lets you actively test what’s happening on it. And if you need to replace that module, we will show you where the automaker installed it on the vehicle.
A single offline ECU, poor signal or network fault can create codes across multiple systems. Seeing the network—and being able to test communication directly—can help the technician isolate the source of the problem instead of chasing every code individually. For the shop owner, that can mean less unproductive diagnostic time and another opportunity to be the shop that fixes the vehicle.
Communicate With Today’s Vehicles
The diagnostic connector may look familiar. What’s happening behind it isn’t. Late-model vehicles increasingly rely on advanced communication technologies such as CAN FD (Controller Area Network Flexible Data-Rate), DoIP (Diagnostics over Internet Protocol) and Automotive Ethernet.
A professional diagnostic platform needs the hardware and software capability to communicate using the protocols and network architectures built into these vehicles. Without it, even an advanced scan tool may be unable to properly communicate with systems that need to be diagnosed or serviced.
And this isn’t technology that’s years away. CAN FD, DoIP and Ethernet-equipped vehicles are already rolling into independent repair bays.
You’re not only buying a diagnostic tool for the vehicles you’ve serviced for the past ten years. You’re buying one for the vehicles entering your bays tomorrow.
Bring in an Expert Without Sending Out the Car
Sometimes the diagnosis and physical repair are complete, but the vehicle still needs a TSB software update, complete module programming, or ADAS calibration on a new vehicle. Does that mean the vehicle now has to leave your shop?
The Autel Remote Expert platform gives participating shops another option. Using compatible Autel equipment, shops can connect with pre-qualified, brand-specific diagnosticians for supported remote services.
And these aren’t people who learned the job from a manual. They are experienced automotive professionals who have spent decades working on the same kinds of difficult vehicles and problems your technicians see in the bay.
Autel Remote Expert Sheldon Smith of DCR Auto Programming Inc. has more than 20 years of automotive industry experience, specializing in OEM programming, module coding and ADAS calibration across domestic, Asian, European and exotic vehicles.
Remote Expert Bryan Codoluto of Filling and Service brings more than 24 years of automotive experience, with specialties including module programming, immobilizer and security systems, ADAS calibration and electrical diagnostics.
That’s the value of Remote Expert. When a job requires specialized knowledge, OEM software, or programming capability, you’re connecting with an experienced automotive diagnostician who works with these systems.
Your technician handles the vehicle in the bay. The Remote Expert brings specialized capability to the job when it’s needed.
Diagnose it. Repair it. Bring in the expertise you need. Finish the job.
How Many More Jobs Can You Complete?
No shop needs to perform every possible service. But there’s a difference between choosing to outsource a job and having to give it away because your equipment can’t take you any further.
That’s the question worth asking when evaluating a professional diagnostic platform.
Not: “How many features does this tool have?”
But: “How many more jobs can we complete with it?”
Can you get through the secure gateway? Find the special function? Locate and ping an ECU to test network integrity? Communicate using CAN FD, DoIP and Automotive Ethernet? Bring in an experienced Remote Expert for programming, coding or adaptations?
Each capability removes another reason to send a vehicle—and its repair order—down the street. And when your shop can complete the service, you’re doing more than keeping today’s revenue. You’re giving that customer another reason to come back—and another reason to tell others:
“Take it to my shop. They’ll get it done.”
