Power should be present at both terminals of the brake switch when the brake pedal is applied. Electrical components that use the chassis ground will suffer high resistance in the ground circuit if the mounting bolts are loose. Testing is available 12 months out of the year and there are weekend times available as well. In simple terms, a diode is a one-way check valve in an electrical circuit. When the pedal is depressed, the brake switch completes the circuit supplying power to the brake lights.
An open at point B results in no voltage input to the coil and a misfire code at both the number 1 and 4 cylinders. There is an open at point A in the system. An open at point D of the system. This type of question should be read carefully. The correct answer is the answer that doesn't fit. A short to ground at point C activates the relay causing the fan to run when the ignition is switched on, even when the engine is cold. Which of the following would result in this continuous fan motor operation? You are searching for the answer that is false.
An open at point B results in no fan operation. If you want to familiarize yourself with the interface, you can use the demo on the website to check out the actual format. Technician A says with the brake pedal depressed, there should be power present at both ends of the brake switch. You can also access an L3 practice test on the website. Advancing in your can be a challenge, but there is something you can do to increase your chances of earning a better mechanic salary and becoming more desirable to employers.
This is the engine coolant temperature sensor. . Both A and B are correct. At the end, you will receive feedback in a performance review, which tells you which questions you got right or wrong. Taking advantage of all available resources, including L3 study guides and practice tests, will help you to be as prepared as possible to pass the exam on your first try. Both A and B are correct. An open at point D will prevent fan motor operation.
There is excessive resistance at point D of the system. You purchase the vouchers at the above cited rates, and then use the resulting code to take whichever test you choose. A short to ground at point C in the system. The practice version of the test is half the length of the real thing. Neither A or B 10. This page only contains practice questions there will be a link to another Page with the answer key and explanations.
The extra questions are not marked on the test so you will still need to complete the entire thing to the best of your ability. Excessive resistance at point A of the system. The computer uses them to control different actuators, like the coils shown above, usually by grounding the control circuit. An open at point B in the system. The pedal is depressed, and there is power at the switch, but no power coming out.
Now the first time I seen this it took me awhile to figure …. This particular certification requires three years of automotive repair experience as opposed to the two required for other categories. There is an open at point B in the system. There are codes indicating a misfire in number 1 and 4 cylinders of a four cylinder engine. This is because the control module is unable to control ground the open circuit. Technician B says this condition indicates that there is an open in this brake switch.
A pedal mounted brake switch is being tested with a voltmeter. It allows current to flow in one direction without returning back. Point A is a common ground for both drivers. They are administered online and are accessible via a voucher system. This is Pre-Test is content from your Advance Scan Tool and Emissions Diagnosis Manual, to assist you with the Final Examination and hopefully answer any questions you may have had in the classroom. There is an open at point C in the system.
This changes the normal flow, because with this question the correct answer is the answer that is most likely correct. Remember as you're eliminating answers, to eliminate answers that are correct and fit the question. Resistance in this circuit will corrupt the signal from the sensor. . .
