E$E2 GRADE A QUESTION AND ANSWER FULLY ANSWERED
When the park light switch is closed current flows from the battery through the fusible
link to the park light switch where it is fed through the fuse to the - (correct answer)front
park lights side marker lights and to the rear tail and license plate lights
Even the most basic vehicles include many electronically controlled systems If each
electronic system had its own ECU harness and sensors, the complexity and circuitry
would increase dramatically How can this be overcome? - (correct answer)By the use of
a multiplexed serial communications network to reduce the need for additional wiring
The headlight circuit consists of - (correct answer)the battery fusible link and fuses head
light switch headlight relays dipper switch head lights high beam indicator light wiring of
a suitable size and the ground circuit
The emergency flasher system operates which lights on the vehicle? - (correct
answer)Both front and rear turn signals at the same time
Tech A says that too high of charging system voltage can shorten light bulb life.
Technician B says a bad ground wire can shorten light bulb life. Who is correct? -
(correct answer)Technician A only Correct Bulb life is decreased as applied voltage is
increased High resistance in the ground circuit lowers applied voltage making the bulb
dimmer and longer lived
Bulb filaments are normally made from - (correct answer)tungsten
Drivers using High Intensity Discharge or HID lights are able to see the road
approximately - (correct answer)300 feet or 100 meters
Cornering lights are on at all times to assist drivers see the curb and any obstacles that
may not be illuminated by the headlights - (correct answer)False
