Do the letters “GDI” scare you? If gasoline direct injection or GDI has you avoiding diagnostics and repairs on late-model vehicles, we have some training for you! In this 45-minute webinar, experts will help you understand GDI systems from the strainer in the tank to the nozzles in the combustion chamber.
At the end of the webinar, you will have a better understanding of how a GDI fuel system operates, so you have a solid diagnostic foundation.
Speakers Jeff Boehler, Director of Engineering/Chief Engineer, Autolite Andrew Markel, Director of Content, ShopOwner

For any electric vehicle, the alignment not only protects the tires, it helps to increase the range.
Once you pull a Tesla Model S onto an alignment rack, you quickly realize that it shares many of the same suspension components as conventional vehicles. Aligning a Model S is just like any other vehicle, and many alignment systems have the specs in their database.
The Model S has an optional air suspension package. The air struts automatically self-level, even when power is off. The system needs to be disabled before you lift the vehicle. You can put the vehicle into jacking mode using the settings menu of the touch screen.
For alignment, the suspension needs to be set to the high position. After the suspension has been put in the high position, put the suspension in the jack or service mode using the touch screen before measuring the ride height.
The secret to performing a rolling compensation alignment on a Tesla Model S is in the door latch. To be able to roll the car in neutral is to trick the door latch to think the door is closed and a driver is behind the wheel. First, buckle the seat belt before you sit in the vehicle. With the key fob inside the car, sit in the driver’s seat and press the brake pedal to turn on the vehicle. The speedometer and gear indicator should be on in the instrument cluster. Shift the vehicle into neutral and release the parking brake.
Without leaving the seat or releasing the brake pedal, open the door. Using a small pen or screwdriver to engage the door latch, push it into the second detent so the vehicle thinks the door is closed. You can now exit the vehicle while it is in neutral.
The front suspension uses a tall steering knuckle with two lower control links and a single upper control arm. Camber is adjusted using an eccentric on the inboard side of the front link. Caster can be adjusted using the inboard eccentric on the rear link.
If a significant change to the toe was made during the alignment, it may require a recalibration procedure using the Tesla factory scan tool. But small changes to the toe will not change how the AutoPilot system works.
The only factory adjustment is the toe angle. It can be adjusted with an eccentric on the upper control arm. Camber is not adjustable, but many cars suffer from excessive negative camber. If the camber is out of specification, check the ride height and condition of the bushings. Adjustable links were available from Tesla, but are no longer in their parts database. Aftermarket options are out there from specialists.
After the toe is adjusted or the thrust angle is changed, the steering angle sensor must be reset. The reset can be performed with a factory or aftermarket scan tool with the correct software. Without the reset, the driver may notice an off-center steering wheel and a slight steering pull. The driver may also comment that the AutoPilot function is not available or drops out.
The reset procedure is to put the steering system with the scan tool and go for a test drive. If the sensor is not reset, it could take several drives for the sensor to self-calibrate.
Aligning any Tesla is not rocket science. They still have the same tire wear issues as any vehicle — in fact, the Tesla is hard on tires due to the torque produced by the electric motors. Having the suspension angles properly aligned can make sure the owner gets the full life out of a set of tires.
