Control arms connect a vehicle's suspension to the frame. The connection to the frame uses:
bushings |
|
pins |
|
knuckles |
|
ball joints |
Control arms (upper and lower) connect a vehicle's suspension to the frame. The connection to the wheels is through ball joints which allow the control arms to turn and move up and down simultaneously. The frame connection uses bushings.
The fuel injector is regulated by the __________ which is the main computer that controls engine and transmission functions.
vehicle control module |
|
computer control module |
|
powertrain control module |
|
transmission control module |

Which of the following is not a function of a car battery?
delivers current to the ignition system to start the engine |
|
acts as a supplemental source of energy to moderate engine performance |
|
delivers supplemental current when the alternator can't handle high electrical system loads |
|
acts as an electrical reservoir for excessive current |
The lead-acid battery is the core of the electrical system, providing current to the ignition system to start the engine as well as delivering supplemental current when the alternator can't handle high electrical system loads and acting as an electrical reservoir for excessive current.
