While discussing working on hybrid vehicles: Technician A says to make sure that the high- voltage system is shut down and isolated from the vehicle before working near or with any high-voltage component. Technician B says that when working on or near the high-voltage system , even when it is de - powered , always use insulated tools. Who is correct ?
While discussing what is indicated by a vehicle’s charge indicator: Technician A says that any positive reading on an ammeter shows that the generator is in working condition. Technician B says that if the voltmeter reading does not increase immediately after starting the engine, the battery is bad. Who is correct?

Which of the following statements regarding the “Pre-Emission Inspection Check” Of a diesel powered vehicle that is subject to Opacity (Smoke Meter) testing is not true?
The governor (if equipped), the exhaust system, and the emissions control devices must all be checked.
The exhaust system must be checked for any missing sections which would prevent collection of a valid exhaust sample.
Vehicles not meeting requirements cannot be inspected. This is not considered an inspection or rejection and no fee is to be charged.
The governor, if originally equipped, must be checked for presence, connection, and operation.

- Which of the following statements about the SRS warning lamp is not true? When the ignition is first turned on, the indicator should turn on and remain on for approximately 6 seconds. If the system seems to be able to work correctly, the lamp will stay lit as the engine runs. If the lamp flashes or turns off and then turns on again, low source voltage may be indicated. A system problem is indicated when the lamp does not turn on when the ignition is initially turned on.arrow_forwardThe yellow electronic throttle control warning lamp comes on occasionally while the vehicle is driven; Technician A says that this means there is a problem with the system.

CO2 levels are highest when the air-fuel ratiois slightly leaner than stoichiometric.b. The production of CO2 is directly related tothe amount of fuel consumed; therefore,more fuel-efficient engines produce less CO2c. To reduce CO2 levels in the exhaust, engineers are working hard to decrease fuel consumption to keep CO2low.d. The concern for CO2 emissions is one of theprimary reasons for the delayed use of alternative fuels for automobiles.arrow_forwardWhich of the following statements about fuel trim is not true? a. A positive fuel trim value means that the PCM detects a lean mixture and is decreasing the pulse width to add more fuel to the mixture. b. Short-term fuel trim represents changes made immediately in response to HO2S signals. c. Long-term fuel trim represents changes made to set a new base pulse width. d. Long-term fuel trim responds to the trends of the short-term fuel trim.arrow_forward
