Electrical
The type of fault that results from the power wire touching ground before the load.
What is a short circuit.
What is the positioning of the condenser in relation to the radiator in a vehicle?
Condenser is in front of the radiator. Meaning air flows through the condenser first and then the radiator.
Self diagnostic systems display these to alert the technician of a trouble area.
What is a DTC.
As measured with a DMM, an NTC thermistor's resistance does this when the temperature increases.
What is decreases.
The color of high voltage conduit. (above 50v)
What is Orange.
You must never bypass a load with this diagnostic tool.
What is a fused jumper wire.
The default position on a system that has lost all vacuum supply.
What is the defrost/floor vents.
This monitors the radiant heat load that might cause an increase of the in-vehicle temperature.
What is the Sun Load sensor.
This component is full of electrical potential even though there may not be a circuit connected.
A charged vehicle battery.
The toyota prius storage tank can hold hot coolant for this number of days.
3
All of these have this result.
Too small diameter wire, internal wire corrosion, loose terminal connection.
Reduction in current flow.
Air flow enters the ducting from inside the vehicle during this cooling setting.
What is Max A/C.
The temperature fluctuates between hot and cold. Which of the following is the most likely cause?
A. blower motor
B. low refrigerant level
C. coolant temp sensor
D. disconnected aspirator tube.D. disconnected aspirator tube.
The resistance in a circuit can be measure using this specific meter.
And the current can be measure using this specific meter.
What is an ohmmeter and an ammeter.
A dual A/C compressor has this percentage of the capacity driven electrically.
15%
If a system designed with 2.0 to 3.5 ohms of resistance has a change of resistance to 1.5 ohms. This will happen.
This system type has all the incoming air flow through the evaporator first and then the heater core.
What is the reheat system.
The technician diagnosing a system that will not hold the desired temperature set at the panel should do this first. (after verifying the concern)
What is check for DTCs and read the OEM information.
The DMM is hooked into the circuit in this manner to measure the voltage dropped across a component or corrosion.
What is parallel.
This is the abbreviation for electrically driven compressor oil.
What is POE.
During heavy acceleration a vehicle has sluggish performance when the A/C is on. This system is most likely at fault.
What is the engine load A/C cut-off system.
This causes a change of air flow from center vents to the defrost vents during hard acceleration on a vacuum controlled system.
What is a faulty vacuum check valve.
(wiring diagram question)
A
A good quality DMM has high ______ ______ in the voltage measuring mode.
What is internal impedance.
This component is used to help keep the passenger compartment warm while the ICE is off during idle/stop.
What is the auxiliary coolant pump.
