Top critical review
Not very accurate and trailing the actual ASE test material
Reviewed in the United States on December 20, 2019
Author changes the names of the devices that have never been heard or read in previous automotive books and material. For example on page 68 question 29 he asks "which of the following devices regulates the brightness of the dash light"? Among the answers ...C. Dimmer switch, D. Rheostat. We know dimmer switch is a rheostat type of switch so the correct answer Dimmer switch? NO the author says rheostat and that the dimmer switch is used to dim or brighten the "headlamps" which was very mindboggling. Chapters later I realized by dimmer switch he means the high beam low beam switch.
In another question he asks " what causes the interior light to stay on all the time"? among the answers, B. defective dome light switch and this is a false answer although defective dome light switch can cause the lights to stay on for example when you move the switch from ON to DOOR. I the switch is internally bad, the selection wont take place and the lights remain on ON all the time when the switch is showing DOOR.
About 95% of the practice questions were in the Tech A / Tech B format and about 5% diagrams when the actual test that I took 2 days ago had only 2 tech A/Tech B questions and had many elaborate diagrams with open or short somewhere that needed 3 to 4 minutes just to get hold of the diagram to pick the right answer. Recertification test for A6 has 25 questions with 45 minutes time meaning 1.8 minutes for each question. I passed the test but had to rush through it and still came up short on time. This was my 4th recertification test. Toughest questions were grouped at the beginning of the test and were of the type that this book did not prepare me for it. One of the malicious questions was showing several modules communicating through CAN BUS lines which are twisted wires and in the diagrams they were also twisted making them very hard to follow and there was nothing similar in this book.
As vehicles become more complex electrically and electronically, ASE questions for A6 become more complicated and complex but the time to answer them remains the same. I had the same amount of time that I had 12 years ago.
