To cause inflation, closing of the ________ is required to provide the power-side voltage to the inflator module. - ANS Arming Sensor A(An) ________ is the time and distance between two consecutive points, either high or low. - ANS Wavelength Technician A says that FM requires an antenna whereas AM may be heard from a radio without an antenna. Technician B says that the radio antenna may be a component of the rear window glass. Which technician is correct? - ANS Tech B A defective APP sensor will cause ________. - ANS Both A and B Which of the following actions will deactivate cruise control operation? - ANS Applying breaks The force required to deploy a typical airbag is approximately equal to the force of a vehicle hitting a wall at over ________ miles per hour - ANS 10 What enables an air bag to deploy in an accident, even if the battery becomes disconnected during the crash? - ANS Back up power supply Which of these is required for XM radio reception? - ANS Both A and B What device passes AC interference to ground and blocks DC voltage, and is used to control radio interference? - ANS Capacitor Technician A says that air bag electrical terminals are copper-plated to protect against corrosion. Technician B says that pretensioners are explosive (pyrotechnic) devices which remove the slack from the seat belt and help position the occupant. Which technician is correct? - ANS Tech B On a vehicle equipped with an occupant detection system, how much weight is required in the seat before the passenger airbag deploys at full force? - ANS More than 99lbs Technician A says that a braided ground wire is best to use for audio equipment to help reduce interference. Technician B says to use insulated 14 gauge or larger ground wire to reduce interference. Which technician is correct? - ANS Tech A A radar cruise control system is designed to ________. - ANS 13. Maintain a set distance between vehicles The temperature of heated seats is regulated by ________. - ANS A seat cushion temperature sensor and seat module A remote keyless control stops working. Technician A says that the battery in the remote could be dead. Technician B says the key fob may have to be resynchronized. Which technician is correct? - ANS Both Tech Technician A says that crossovers are used to block certain frequencies to allow each type of speaker to perform its job better. Technician B says that a high-pass filter is used to block high-frequency sounds being sent to large woofer speakers, and a low-pass filter blocks low-frequency sounds being sent to tweeters. Which technician is correct? - ANS Tech A A vehicle is being repaired after an airbag deployment. Technician A says that the inflator module should be handled as if it is still live. Technician B says rubber gloves should be worn to prevent skin irritation. Which technician is correct? - ANS Both Tech An antenna lead-in wire should have how many ohms of resistance between the center terminal and the grounded outer covering? - ANS Infinity (OL) If two 4-ohm speakers are connected in series, meaning the positive (+) of one speaker is connected to the negative (-) of the other speaker, the total impedance will be ________. - ANS 8 Ohms Technician A says that the cruise control on a vehicle equipped with an electronic throttle control (ETC) system uses a servo to move the throttle. Technician B says that the cruise control on a vehicle with ETC uses the APP (Accelerator Pedal Position) sensor to set the speed. Which technician is correct? - ANS Neither Which of these is the heating element used to ignite the gas-generating material, usually sodium azide? - ANS Squib A typical radar cruise control system uses ________. - ANS All of These Two technicians are discussing dual-stage airbags. Technician A says that a deployed airbag is safe to handle regardless of which stage caused the deployment of the airbag. Technician B says that both stages ignite, but at different speeds depending on the speed of the vehicle. Which technician is correct? - ANS Neither Tech To safely install a power amplifier in-line capacitor, it must first be ________. - ANS Pre-charged Technician A says that a radio can receive AM signals, but not FM signals, if the antenna is defective. Technician B says that a good antenna should give a reading of about 500 ohms when tested with an ohmmeter between the center antenna wire and ground. Which technician is correct? - ANS Neither Tech All power windows fail to operate from the independent door switches but all power windows operate from the master switch. Technician A says that the window lockout switch may be on. Technician B says that the power window relay could be defective. Which technician is correct? - ANS Tech A If only one power door lock is inoperative, a possible cause is ________. - ANS Defective door lock motor or solenoid The electrical terminals used for airbag systems are unique because they are ________. - ANS Gold Plated More than one signal can be carried by a radio wave using a process called ________. - ANS Sideband operation Technician A says that a defective ground connection at the master control switch (driver's side) could cause the failure of all power windows. Technician B says that if one control wire is disconnected, all windows will fail to operate. Which technician is correct? - ANS Tech A When checking the operation of a rear-window defogger with a voltmeter, ________. - ANS The voltmeter should indicate decreasing voltage when grid is tested across width of glass
