Exam 21: Instrumentation and Information Displays

On most new vehicles, the action of an ECT (engine coolant temperature)sensor can be monitored on a scan tool.

The park distance control system warns the driver that the vehicle is close to an obstacle by _____.

The two types of electrical analog gauges are magnetic and ____________________.

Park distance control systems are being discussed. Technician A says that as the distance between the vehicle and an object becomes closer, the intervals between the warning tones become longer. Technician B says that some systems have both visual and audible warnings. Who is correct?

Which of the following is NOT a component of an analog gauge system?

Technician A uses a universal gauge tester to diagnose gauge problems. Technician B uses a scan tool to test the ECT (engine coolant temperature)sensor. Who is correct?

A(n)_____ coil is installed in the IVR power lead to prevent radio interference caused by pulsations of the IVR.

The correct term for a modern dashboard is ____________________.

A heads-up display projects visual images on the ____________________.

The oil change maintenance reminder on a Honda is automatically reset by a switch contact in the oil filter housing that is tripped whenever the oil filter is removed.

The vehicle speed sensor (VSS)for an electronic speedometer on an RWD vehicle is typically mounted _____.

Most digital speedometers have a speed limit. If the vehicle exceeds the speed value, the speedometer continues to display the top of its range.

An engine coolant temperature sending unit may be called a piezoresistive sensor.

All the following are items to be checked in gauge systems EXCEPT:

Analog gauges use digital displays of numbers.

All electrical gauges require an input from either a ____________________ or sensor.

Tire pressure monitor systems are being discussed. Technician A says that when the indicator light is yellow, the pressure in one of the vehicle's tires is below minimum. Technician B says that when the indicator is red, the tire pressure is excessively low or almost flat. Who is correct?

An oil pressure sending unit may be called a piezoresistive sensor.

What is a HUD system and how does it work?

Technician A says most digital temperature gauges are bar-type displays. The number of illuminated bars varies according to the current flow from the sending unit. Technician B says some warning lights are triggered by the PCM and BCM. Who is correct?
