High voltage injector drivers work differently than those used in sequential injection systems. They use the same principle used to power diesel injectors use to produce high voltage. Watch to learn more.
A fuel pump module can be tested reasonably well with just a meter that can measure frequency and duty cycle. However, just measuring the voltage can lead to replacing perfectly good parts.
The ability to explain even the most basic of concepts of automotive service, such as why oil wears out and needs to be changed, is an extremely useful skill to have for communicating with new customers.
Generic OBDII scanners have their uses, but they cannot identify a problem with the same level of accuracy that an enhanced scan tool can.
When removing a high voltage part from a hybrid vehicle, the live dead live test is useful to make sure the vehicle did in fact power down properly.
