ASE - A2 Questions
A line stress check suggests low stress at idle in all ranges on an electronically controlled
automated transmission. Which of the subsequent can be the reason? - ANS-A hassle within
the oil pump or oil pump stress regulator will reason low stress at idle in all tools ranges. Answer
option A is wrong because a misadjusted TPS can reason high line strain at idle now not low. B
is inaccurate because a problem with the ATF temperature sensor will motive excessive line
strain at idle not low. C is wrong due to the fact an open in a losing resistor circuit will reason
excessive line pressure at idle no longer low pressure.
All of the subsequent are industry-trendy methods used to reprogram the EEPROM: -
ANS-Remote, direct and off-board programming
An automatic transmission pressure test will perceive which of the subsequent? - ANS-dirty filter
out will purpose decrease line stress and the opposite selections indexed will no longer.
DTC (Diagnostic problem code) P0705 PNP (park/impartial position) switch circuit is being
diagnosed. Technician A says this code units while the TCM (Transmission Control Module) or
PCM (powertrain manage module) does no longer receive the perfect voltage signal from the
park/impartial position (PNP) transfer. Technician B says the park/impartial role (PNP) switch
circuit will be open or shorted. Who is right? - ANS-Both technicians are accurate. A because
the Diagnostic problem code sets while the TCM or PCM does no longer obtain the suitable
voltage sign from the park/neutral role transfer. B because the park/neutral role (PNP) switch
being open or shorted would additionally set a DTC.
On an electronically controlled four-pace automated transaxle, you revel in a "shock" whilst
shifting from "N" to "D." Which of the following would require an OFF-car restore? - ANS-The
best OFF-vehicle restore indexed for a automobile that famous a surprise while moving from "N"
to "D" variety is the FORWARD grasp. All of the other distracters are ON-vehicle upkeep.
Preliminary analysis on an electronically controlled computerized transmission/transaxle
consists of all the following assessments: - ANS-Line stress take a look at, Fluid Check and Stall
Test
Technician A says engine, suspension and driveline troubles can also seem like resulting from
the transmission or transaxle. Technician B says you start with the easy inspections first to
ensure that you haven't overlooked something and you may use the scan tool for further
rationalization. Who is right? - ANS-Both technicians are accurate. Tech A is proper because
many suspension and driveline concerns and noises may additionally look like resulting from the
transmission or transaxle, when they're due to the suspension. For prognosis, you put the
transmission in neutral and see if the concern changes or is going away. If it goes away, the
automated transmission should be investigated. Tech B is proper because you always do the
smooth and simple inspections first to ensure that you have not unnoticed something and you
could use the test tool for further clarification
Technician A says low line stress on an electronically controlled line pressure can motive the
transmission to slip and operate sluggishly. Technician B says line pressure varies with engine
velocity. Who is proper? - ANS-Technician A is correct because low line stress can reason the
