ASE - A2 Questions
You are using a diagnostic symptom chart to diagnose an electronically controlled 5-
speed automatic RWD (rear wheel drive) transmission with a strange noise in drive.
Technician A says the control valve could be the cause and is an OFF-vehicle
procedure. Technician B says the oil pump assembly could be the cause and is an
OFF-vehicle procedure. Who is right? - answer Technician B is correct because the oil
pump assembly could be the diagnostic item and is an OFF-vehicle procedure.
Technician A is wrong because the control valve is likely to be the cause in an ON-
vehicle procedure, NOT an OFF-vehicle procedure.
On an electronically controlled 4-speed automatic transaxle, you experience a "shock"
when shifting from "N" to "D." Which of the following will require an OFF-vehicle repair?
- answer The only OFF-vehicle repair listed for a vehicle that exhibits a shock when
shifting from "N" to "D" range is the FORWARD clutch. All of the other distracters are
ON-vehicle repairs.
Preliminary diagnosis on an electronically controlled automatic transmission/transaxle
consists of all the following tests: - answer Line pressure test, Fluid Check and Stall
Test
Technician A says engine, suspension and driveline problems may appear to be caused
by the transmission or transaxle. Technician B says you start with the simple
inspections first to ensure that you have not overlooked something and you can use the
scan tool for further clarification. Who is right? - answerBoth technicians are correct.
Tech A is right because many suspension and driveline concerns and noises may
appear to be caused by the transmission or transaxle, when they are caused by the
suspension. For diagnosis, you put the transmission in neutral and see if the concern
changes or goes away. If it goes away, the automatic transmission should be
investigated. Tech B is right because you always do the easy and simple inspections
first to make sure that you have not overlooked something and you can use the scan
tool for further clarification
You are checking fluid color on an automatic transmission/transaxle. Which of the
following will cause the fluid to be varnished with a light to dark brown color? -
answerOxidation from under or overfilling will cause the fluid to be varnished with a light
to dark brown color.
DTC (Diagnostic trouble code) P0705 PNP (park/neutral position) switch circuit is being
diagnosed. Technician A says this code sets when the TCM (Transmission Control
Module) or PCM (powertrain control module) does not receive the correct voltage signal
from the park/neutral position (PNP) switch. Technician B says the park/neutral position
(PNP) switch circuit could be open or shorted. Who is right? - answerBoth technicians
